Here at My Pet Nutritionist, we use a combination of healthy diets tailored to your pet’s needs, alongside beneficial gut-friendly herbs, and nutraceuticals. These supplementary additions often come with hosts of benefits, when used in the correct way, for a specific purpose. We often get asked about the various herbs and nutraceuticals we recommend in various blog posts and in our recipes and supplements – you can learn more about some of these here! What Are Gut Healing Herbs? Herbs high in mucilage are often known as the ‘gut healing herbs’. These herbs are usually considered to be a source of prebiotics – food for probiotics; however these herbs have another very important function when it comes to gut health! Mucilage is a soluble dietary fibre, which produces a mucus-like substance which lines the gut wall. When the gut wall is lined with this slimy textured substance, it forms a protective barrier to reduce the risk of further gut damage, and allow the gut to heal. Inflammation is then reduced due to lack of irritation. Mucilage has a fantastic soothing effect on the digestive tract too – those with acid reflux, or having recovered from illnesses like kennel cough which may cause throat irritation may find a powdered form best, due to the soothing effect of the mucilage in these herbs. As an additional benefit of these popular gut healing herbs, the mucilage can increase digestive performance resulting in better stools; this is due to the mucilage adding bulk to the stool (reducing constipation), aiding water absorption, and increasing gut motility. Some studies also suggest that mucilage rich herbs may reduce the build up of cholesterol, and aid the regulation of blood sugar levels. Frequently used mucilage herbs include slippery elm, marshmallow root, and deglycyrrhizinated liquorice root – we will look closer at these later. Findings Here Findings Here What Are Nutraceuticals? Nutraceuticals are components of foods that bring benefit to health. You may often come across plant based supplements for pets; these are packed full of nutraceuticals! Functional foods are also classed as nutraceuticals. Many nutraceuticals enhance basic nutrition, whereas some provide medicinal properties. Some benefits of using carefully selected nutraceuticals include improved overall health, prevention of chronic disease, increased longevity and all round structural support for the body. The term ‘nutraceutical’ is a combination of the words ‘nutrition’ and ‘pharmaceutical’ – meaning they share the same properties as pharmaceuticals, but are acquired through nutrition Functional herbs, antioxidants, probiotics, vitamins and minerals are all examples of the categories most commonly encountered in the world of pet nutrition. We will delve into these categories in terms of nutraceuticals later. Findings Here Findings Here When Should We Use Gut Healing Herbs and Nutraceuticals? A question we often hear at My Pet Nutritionist, is “should we be giving any supplements?” – and our answer is always “if your pet could benefit from a carefully selected supplement, then absolutely!”. It is important not to needlessly add lots of different nutraceuticals and gut healing herbs to your dog’s diet, unless they require/could benefit from it. When it comes to giving mucilage herbs, these can be incredibly beneficial in situations where gut damage is apparent. Situations a mucilage herb may be beneficial include: Allergies: due to an immune malfunction Intolerances: due to gut damage or leaky gut syndrome Following vaccines, worm or flesa treatment: these products are very damaging on the gut, so gut healing may be necessary. Acid reflux: soothes the digestive tract and reduces the risk of acid reflux Upset stomach or constipation: these herbs help to rectify loose or solid stools when needed. Great to have in the first aid cupboard! When looking at nutraceuticals, we need to look at the symptoms your dog or cat is displaying, alongside gaining a diagnosis from your veterinarian. Some types of illnesses you may use nutraceuticals for include: Joint issues Skin issues Digestive issues Cognitive health issues (anxiety etc) Vision issues As brilliant as nutraceuticals can be as part of your pet’s health regime, many do come with some contraindications with pharmaceuticals your pet may need. Contraindications are negative interactions with drugs – these interactions can often cause downregulation of the drugs themselves, leaving your pet vulnerable to disease progression. An example of this is curcumin – the active compound in turmeric. It is fantastic for joint support/arthritis, cardiovascular function, reducing inflammation, eradicating free radicals, immune support, cognitive ability and cancer prevention. The reduction in pain in those who take curcumin is vast; however some individuals may require pain pharmaceutical pain relief for their condition. Curcumin is known to downregulate the effects of some pharmaceutical analgesics, as well as various other drugs. It is always best to check with your veterinarian before starting a new nutraceutical, if your pet is on pharmaceutical drugs. Findings Here Findings Here Popular Gut Healing Herbs The three most popular gut healing herbs can all be found inside our Gut Guardian supplement, along with probiotics and chamomile. Lets take a closer look at these mucilage herbs! Marshmallow Root: this is a sweet smelling and tasting herb derived from the Althaea officinalis plant. When combined with water, it immediately forms a thick, slimy substance due to it’s high mucilage content. Traditionally, marshmallow root is used in cases of digestive or respiratory issues, and also topically to soothe skin issues. As well as being high in mucilage, it also contains high amounts of antioxidants, anti-inflammatory properties, and antibacterial properties. slippery elm: like marshmallow root, slippery elm produces a slimy substance when combined with water. It originates from the inner bark of the slippery elm tree (Ulmus rubra), and is often used to treat digestive issues, and sore throats by lining the oesophagus. DGL (deglycyrrhizinated liquorice): this herb increases mucous production in the body, which helps line the stomach, reducing the risk of harm caused by acid. DGL is thought to have properties to treat ulcers too! Findings Here Findings Here Findings Here Popular Nutraceuticals There are many nutraceuticals used in the
If you use social media, or dog health forums, you may have heard fellow pet parents mentioning ‘cool’, ‘warm’, ‘hot’ and ‘neutral’ foods. The recommendation for itchy dogs, tends to be to use ‘cool’ foods if we look at nutrigenomics and the principle of food energetics. Here at My Pet Nutritionist, we wanted to dedicate a blog to ‘cool foods’, and feeding them to itchy dogs, so we hope this blog post answers any questions you may have! Yin-Yang Nutrition Yin-Yang Nutrition is a Traditional Chinese Medicine concept which categorises foods into four pillars – Cool, Neutral, Warm and Hot. Which category each protein is linked to, depends on that food’s characteristics. Balance is the basis of Yin-Yang Nutrition, and is what determines whether an individual should eat cool, neutral, warm or hot food sources. Lets take a look at the clinical symptoms of and abundance and deficiency of yin and yang. If your dog has an abundance of Yang…they have excessive heat as they’re unable to counteract warming properties. Heat needs to be removed, so cool foods are required. Clinical signs of dogs with an abundance of yang include: Acute onset, usually at a younger age Short course No general weakness High fever Hyperactivity Elevated heart rate Strong heartbeat Tongue discolouration – usually red or purple If your dog has a deficiency of Yang… the body lacks warming properties enough to combat the normal level of Yin in the body, so warming foods are required. Clinical signs of dogs with a deficiency of Yang include: Chronic onset, usually at an older age Long course Low body temperature at the extremities Loose stools Urinary incontinence Swelling of the limbs due to trapped body fluids (Oedema) Chronic weakness and pain Generalised weakness Discolouration to the tongue – usually pale Weak heart rate Deep heart beat Infertility If your dog has an abundance of Yin… they have excessive coldness, and are unable to counteract cooling properties. Warmth needs to be gained, and cold removed, so hot foods should be given. Clinical signs of dogs with an abundance of Yin include: Acute onset, usually at a younger age Short course High pain levels No general weakness Swelling of the limbs due to fluid retention (Oedema) Loose stools Slow heart rate Strong heart beat Tongue discolouration – usually red or purple If your dog has a Yin deficiency… the body lacks cooling properties, enough to combat the normal levels of Yang, so cooling foods are required. Clinical signs of dogs with a deficiency of Yin include: Chronic onset, often at a younger age Long course Generalised weakness Fever, but not high fever Anxiety Increased thirst Seeks cool areas Tongue discolouration – usually red and dry Increased heart rate Findings Here Findings Here If your dog is in perfect balance, then the above clinical signs will not be apparent, and the dog will be healthy, with pink, moist tongue, normal activity levels, a formed stool, no pain, and normal heart rate and beat. When looking at the Yin-Yang theory, these dogs should eat a balance of ‘Cool’ and ‘Hot’ foods, and unlimited ‘Neutral’ foods. Findings Here You can learn more about general Traditional Chinese Medicine here. Which Foods are Cool? So, when we speak of ‘cool proteins/foods’, what do we actually mean? Which foods are cool? Protiens Duck Frog (perhaps not the easiest to source in most countries, but frog meat can be used as part of a balanced DIY raw diet) Rabbit Cod Scallops White fish Eggs Pork turkey Plants Broccoli Cauliflower Turnip Lettuce Cucumber Seaweed/kelp Dandelion Spirulina Swiss chard Wheat grass Button mushrooms Apple Banana Melon Supplements Flaxseed Sesame seeds Itchy Dogs and Cool Proteins Itchy dogs may benefit from being fed cool proteins, in some situations. It can very much depend on the reason the dog is itchy – food intolerances/allergies, or environmental allergies. The problem with food related itching, is that the immunological response to a protein can vary between sources, and isn’t necessarily down to heat in the body. In these situations, working on gut health is important, as is working out which proteins need to be eliminated from the diet. If the dog is suffering with environmental allergies however, the body’s response to an environmental allergen is inflammation, which can often be linked to imbalances in the Yin and Yang. Dogs with itching and allergies tend to have excess Yang. The main element of this, and what we will focus on in this blog, is seasonal allergies. When a dog presents with seasonal allergies, a number of conditions can occur, which can be down to heat invasions with damp elements. Conditions often coming hand in hand with seasonal allergies, as well as occurring independently include generalised itching, eczema, hot spots, interdigital furunculosis, dermatitis, and seasonal alopecia. Dryness during old age can also cause coat and skin changes which present as itching. For itchy dogs suffering with these conditions, feeding a cool diet may be hugely beneficial to getting on top of the itch. While alternative therapies are often frowned upon by the medical community, there are studies to prove the efficacy and safety of Traditional Chinese Medicine, and other natural therapies. Findings Here Findings Here By looking at the dog’s clinical signs closely, you may see some of the less obvious signs of a Yin-Yang imbalance. Once an imbalance is detected, you can tailor the dog’s diet to include more cool proteins, and eliminate any warm or hot ones. As the cooling proteins have an anti-inflammatory effect for those with inflammation in and on the body, the reduction in inflammation will help reduce itching. Ultimately, the Yin-Yang balance will align, and the body will have equal amount of both Yin, And Yang. Theoretically, this will present as perfect health, and eliminated itching. It’s important to bear in mind, that itching could be caused by food sensitivities, which can require a more western approach, and a full elimination diet to be completed. Some evidence does suggest that pruritic dermatitis,
Yeast is a problem we see very often here at My Pet Nutritionist. Owners often feel they have run out of options with regards to treating the yeast, so this guide has been made with the goal of helping you overcome yeast; you may just see something missing from your routine which could be the missing piece for success! What Is Yeast? Yeast, as we commonly call it, comes in two forms – Candida; a fungal pathogen, and Malassezia; a skin based hydrophobic yeast. Candida makes up a small portion of a healthy gut microbiome, and is naturally found in the gut, and genital tract. While candida is a very normal part of a healthy gut, if the gut is not kept in tip top condition, it can cause problems. In the healthy gut microbiome, there are good bacteria, and there are bad bacteria. The good bacteria keep the levels of bad bacteria in check, which means the bad bacteria aren’t able to wreak havoc! When the gut is impaired the opportunistic fungal pathogen, candida will take hold, and grow. Now we have too much of the ‘bad guys’ and not enough of the good bacteria to fight it off, and so candida takes over! Once candida has taken over, and the gut is not healed, we start to see the typical yeast symptoms in our pets. Malassezia often happens as a result of environmental allergies, as the skin barrier is damaged, allowing for the formation of yeast on the skin. Much like inside the gut, the skin has it’s own microbiome, in which the bad pathogens are kept in check by the good. When the good pathogens diminish, the bad ones are able to take over! This is something we see in a vast amount of customers who come to us with a dog with environmental allergies. Symptoms include: Rusty colour, mainly between toes and paw pads, ears, under the tail, and around the groin and armpit areas. It can occur in other places too, but these moister areas are prime location for it! Repetitive paw licking Licking under the tail area Ear scratching and head shaking Excessively rubbing face and body on walls and furniture Hair loss An unmistakable odour; much like a damp, cheesy smell, or popcorn-like smell Sometimes discharge is apparent in yeast cases More Information on yeast can be found here. Let’s take a look at how we can help our dogs battle Candida and Malassezia! Battling Yeast When dealing with yeast, there are many contributing lifestyle and nutrition factors, which may need to be tweaked a little, or added to combat the pathogens, and repair both the gut barrier, and the skin barrier. Diet As always, here at My Pet Nutritionist, we are very fresh food forward. Feeding a dog with yeast is no different – one of the main steps to battling yeast, is cutting out dry food as much as possible. A fresh, balanced diet would be your best option whether it’s raw, or homecooked using one of our balanced recipes. Why does diet matter for those suffering from yeast? Let’s take a look at the composition and manufacturing process of dry foods, first and foremost. Kibble is high in carbohydrates: generally speaking, most kibbles are between a whopping 30 and 70% carbohydrates! Carbohydrates are sugars – a fantastic food source for yeast! The canine body struggles to digest carbohydrates often found dry foods, which causes gut inflammation. Kibble is ultra processed: excessive processing causes the food to become inflammatory. When the gut becomes inflamed, damage occurs, which leaves the microbiome vulnerable, and causes imbalances as the bad microbes out compete the good microbes. Advanced Glycation End Products (AGEs) are produced during high heat manufacturing and extrusion of dry foods. AGEs not only speed up the ageing process, but they have many other health disadvantages too, one being that they expand the life of yeast. We need to cut out products which produce AGEs when we are battling yeast! Findings Here Why can fresh feeding help combat yeast? You can tweak the diet to ensure there’s no starchy carbohydrates. Less ‘food’ for the yeast! It’s much easier on the gut, as it’s highly digestible! This means less gut damage and less inflammation. There’s no high temperatures or vigorous processing involved, meaning no AGEs form! What do we need to include in a fresh diet for yeast sufferers? Our recipes for cooked foods are already balanced for you! However if you are raw feeding, you will want to feed 80% muscle meat, 10% bone, 10% secreting offal (half liver, half other secreting offal, preferably!) with the addition of omega 3 sources like raw eggs, fish oils and oily fish, and algal oils. Some vegetables may be suitable to be added to the diet of a yeasty beastie, but we need to be very selective, and very careful which ones we pick! High fibre, low starch veggies are ideal, if tolerated – it’s wise to start off by giving a miniscule amount of plant matter, and gradually building up to 10% plant matter. Some options are broccoli, kale, and cabbage. Try to avoid starchy carbohydrate plants such as sweet potato, carrot and squash. Supplements There are so many supplements on the market these days – it can feel quite daunting selecting the most suitable ones for your pet. Some are better than others when it comes to battling yeast. Gut healing: gut healing supplements are very important – in order to regain balance in the gut microbiome, we want the gut to be in a good, healthy, and strong state. Mucilage herbs are our friend here! Slippery Elm, Marshmallow Root and Deglycyrrhizinated Liquorice are all great for this purpose! Gut Guardian Probiotics: probiotics are essential for yeast sufferers, as they help to rebalance the gut microbiome, by out competing the bad bacteria, which in turn will aid the recovery of the skin barrier. Once there are sufficient levels of good bacteria, the ratio
Pancreatitis flare ups are often a concerning time for pet owners. With so many associated triggers, tailoring the individual dog’s routine to their needs is very important. One of the triggers we see a lot here at My Pet Nutritionist, is food sensitivities. Read on to learn more about how food sensitivities can be linked to pancreatic flares. A bit about the pancreas The pancreas is a very important organ in the body; it is part of the digestive, and endocrine systems. It’s role in the digestive system is to produce digestive enzymes to aid the breakdown of foods, with fat and protein being the main targets. Within the endocrine system, the pancreas produces insulin; a hormone which controls blood sugar levels. The pancreas is located in the abdominal region, on the right hand side, near the stomach, and above the intestines. The pancreatic duct attaches the pancreas to the small intestine, and transports the digestive juices made by the pancreas, into the small intestine, to be able to begin breaking food down. Before reaching the intestine, however, another duct from the gallbladder joins the pancreatic duct, and transports bile to the intestine. Findings Here When the pancreas becomes inflamed it releases the digestive enzymes it produces too early, which can result in the body starting to digest the pancreas itself, as well as the abdominal cavity; this is a pancreatic flare. Acute pancreatitis happens suddenly whether it is a mild flare, or a severe flare which hospitalises the pet. Chronic pancreatitis on the other hand, tends to happen for longer periods of time, and intermittently – symptoms are generally milder, but more constant than acute pancreatitis cases. Dogs with enzyme deficiencies, nutritional imbalances or intolerances, or other endocrine conditions tend to get chronic pancreatitis as opposed to acute pancreatitis. Dogs suffering with chronic pancreatitis are often found to be deficient in Vitamins C and E, as well as selenium. The main health condition associated with pancreatic flares, is Pancreatitis. Symptoms of a pancreatic flare are as follows: Vomiting Diarrhoea, sometimes bloody Fever/high temperature Increased heartrate Dehydration Digestive difficulties Abdominal pain (the ‘downward dog’ position, are hunched over back are classic signs of this) Low appetite Pressures on the pancreas For those suffering with pancreatic flares, or pancreatitis in general, it is extremely important to recognise, and understand the triggers of a flare. Let’s discuss the major trigger of a pancreatic flare. Fats More specifically, excess fats, and the wrong type of fats! Fat reduction in the diet is one of the most common things we hear pet owners panic about when their dog has pancreatitis, or a pancreatic flare. While excess fats can be very hard on the already inflamed pancreas, some fats such as fish oils and olive oils have been shown to block cellular mechanisms involved in the development of acute pancreatitis. Massively restricting fat may not be completely necessary long term for pancreatitis patients, but short term during a flare, may be worth reducing. We tend to advise 15% dry matter fat content in the diet of a pancreatitis patient, which is around 5% crude fat. In non-severe cases, the fat content can be gradually increased. Feeding a high fat diet, where the dog is unable to fully digest the fat consumed, can put pressure on the pancreas due to high blood fat content. More digestive enzymes are required for digestion of excessive fats, which causes the pancreas to overwork in order to produce those enzymes. Overworking an organ causes inflammation, which leads to health problems associated with that organ; in this case, a pancreatic flare. Carbs A less well known approach among dog owners, carbohydrates should be kept to a minimum in all dogs, but especially in those with pancreatitis. There is a huge link between high-carbohydrate diets, and an increase in excess blood fat. This is why it is important to steer away from dry food/kibble based diets – these are high in carbs, and the high carb content leads to high blood fat content, which as just discussed causes the pancreas to overwork. Findings Here Findings Here Findings Here Findings Here High carbohydrate dry food diets also lack suitable amounts of vitamin E, due to it being an unstable vitamin, and the long shelf life of dry foods causes the vitamin E content to diminish by around 30% just 6 months from manufacture. As previously mentioned, those with chronic pancreatitis tend to be deficient in vitamin E already, so feeding a high carb, processed diet low in suitable vitamin E may not be a great idea. Vitamin E plays an important role in the removal of excess fat from the body. Less Vitamin E = More excess fat = Pressure on the Pancreas Findings Here Food Sensitivities As the main topic of this blog; food sensitivities can put huge pressure on the pancreas, linking them with pancreatic flares. It is incredibly important to work on your dog’s food intolerances so many reasons, pancreatic pressure being one of them. More on this subject later. Genetic Predisposition As with many health complaints, genetic predispositions are very much a problem with pancreatic flares. Whereas all breeds can suffer with pancreatitis, some breeds are more prone than others, purely down to their breed, and genetics. These breeds include: Miniature Schnauzers Miniature Poodles (and crosses of!) Cocker Spaniels Cavalier King Charles Spaniels Boxers Collies To find out more about pancreatitis, and how dietary changes, lifestyle changes, and correct supplementation can help, have a read of our Natural Guide to Pancreatitis! How do food sensitivities affect the pancreas? So, how do food sensitivities affect the pancreas, resulting in pancreatic flares? Food sensitivities are largely down to gut health, and immune modulation. If you are a regular reader of our blogs, you will notice us mention Leaky Gut a lot as well as inflammation. 70-80% of the immune system lays in the gut, so gut health is always paramount! Leaky Gut As per the condition’s name, leaky gut sufferers
Here at My Pet Nutritionist, we see many dog owners worrying about the condition of their dog’s skin. The appearance of keratosis, and risk of secondary infection can be concerning, but there are things we can do to help those suffering with it. Keep reading to find out what it is, and how we can help those with it. What is Keratosis? Usually referred to as Hyperkeratosis, the condition presents as hardened, thickened, and often cracked and very dry skin. The term ‘keratosis’ stems from overgrowth of keratin in the skin. When too much keratin is produced, the skin becomes less supple. Unfortunately, hyperkeratosis often leads to secondary infection when it is not treated promptly. Those with keratosis will usually find it on the paw pads, and nose. While it can happen elsewhere on the body, these are the most common places it is found in our dogs. Many owners ask if keratosis is painful for their dog. Unfortunately keratosis can be very sore and uncomfortable for them, especially those with cracked skin, and secondary infection. The areas can become very inflamed too, which adds to the pain sensation. Causes of Keratosis There are various factors which can lead to your dog getting keratosis. Let’s have a look at some of these. Age is a huge factor in those with keratosis. It is commonly seen in older dogs, of any breed, but it is most commonly seen in elderly cocker spaniels, boxers, beagles, basset hounds, and various bull breeds. Findings Here Infectious Disease Survivors can be more prone to keratosis, specifically those who have had a systemic infection (an infection which affects the whole body), such as leishmaniasis and distemper. Internal upset in the body, very often presents externally as a skin reaction. The skin is very often an outward sign of inward stress. Findings Here Findings Here Systemic Autoimmune Disease such as systemic lupus and pemphigus foliaceus can also lead to keratosis, again, as an outward sign of inward stress. Findings Here Genetic predisposition is a very common cause of keratosis. It is incredibly important not to overlook lineages/parentage of your dog. This is obviously not easily achievable in most rescue dogs, but if you are planning on buying a puppy from a breeder, a history of skin related issues in the breeding stock is very worth asking for. Labradors are particularly prone to hereditary keratosis of the nose, and usually starts between the age of 6 and 12 months, with recurrent flare ups throughout the dog’s lifespan. A lot of healthy individuals who have no other visible reason for the onset of keratosis, will be diagnosed with having idiopathic (no identifiable cause) keratosis. Findings Here Inadequate Diet Type. The method of feeding being used can also affect the possibility of the dog getting keratosis. As always, we would recommend a fresh food diet, as these are minimally processed, and allow ingredients to provide unaltered nutrition. Zinc Deficiency can cause keratosis. Some breeds of dog, namely the husky and the malamute, cannot absorb zinc efficiently, by genetic predisposition. Many other breeds of dog who grow at a rapid rate, mostly giant breeds, may also struggle to absorb zinc efficiently. One of the main reasons we see in a variety of individuals of many breeds, large and small, is zinc deficiency, leading to keratosis – it is the second most common mineral deficiency, and can be tested for through hair analysis and blood testing at the same time. The lack of zinc can contribute to keratosis as it causes the abnormal production of keratin. Findings Here Findings Here Trauma, particularly to one particular area of the skin, keratosis is common. This is because the cells in the skin, called keratinocytes, react to the repeated trauma by producing excess keratin, with the aim of hardening the skin for protection. This is often why many dogs suffer with keratosis on their paw pads; from repeated walking on hard surfaces. Elderly or overweight dogs who sleep or lay frequently on hard floors often struggle with keratosis due to repeated pressure on certain parts of the body. Findings Here Supporting the Body Externally Recovery from keratosis is a two pronged attack, using internal, and external methods. So what can we do externally to help our dogs suffering with keratosis? As keratosis presents as dry skin, the most important thing to do, is moisturise it. Moisturising the area is imperative to healing keratosis. There are so many natural, and very effective products you can use to moisturise. Coconut oil is one of the most popular, and readily available on the market. Other products include an array of natural snout and paw balms from various companies. Look out for those which do not contain unnatural ingredients – look out for products made from one, or a mix of a couple natural oils such as seed oils and coconut oils, and often a combination of dog friendly essential oils and other seed oils. Apply your chosen moisturising product twice per day, and try to avoid letting your dog lick it off. Supporting the Body Internally The second prong of the two-pronged approach, is internal supplementation, and dietary changes. First we’ll look at diet. A fresh diet would be ideal – these give plenty of moisture, vs dry food which contains very little moisture. Fresh foods are also not ultra-processed, so are much more gut, and therefore skin friendly, as there are huge links with the gut and skin health when we look at the gut-skin axis, for which more information can be discovered in our blog. The vast majority of dry foods on the market have been shown to not meet minimum nutritional guidelines, so deficiencies linked to keratosis are very possible. Using balanced fresh food can be much easier to balance, as we know what is in it. Let’s take a look at supplements. In breeds with a zinc deficiency predisposition, it is important to supplement with zinc. Other breeds shouldn’t require this. The other
Paw biting is probably one of the most common symptoms we see among our clients at My Pet Nutritionist. It’s daunting when your dog just wont stop! The noise of paw chewing, every owner of a paw biter knows… it can be draining! Our handy guide may help you understand why your dog is biting his paws, and what you could do to help alleviate it. Exposure to chemicals Exposure to chemicals in various aspects of life, can have a massive effect on your dog’s health – especially gut health, which can lead to symptoms such as itchy paws and undercarriage. Let’s discuss the effects flea and worm treatments, household cleaners, and environmental products can have on itchy paws! Flea and Worm Treatments Flea and worm treatments may seem rather an odd cause of paw biting, as flea and worm treatments are administered either orally, or on the skin. These products are so very damaging to the body, both internally, and externally. Not only can they cause chemical burns, and sore skin, as well as neurological problems, they can also damage the gut. A damaged gut can cause a histamine response in the body, which brings with it, symptoms such as excessive itching and licking, including paw biting. We would recommend switching to natural alternatives for flea and worm prevention. Household Cleaning Products It’s important to be mindful of the ingredients used in household cleaning and laundry products. An enormous amount of the ingredients in many laundry products and cleaning products are skin irritants. Try to use as natural products as possible – some natural pet companies stock natural laundry and cleaning products, probiotic laundry and cleaning products, or you can make your own! But my cleaning product states ‘pet friendly’?! Unfortunately, this simply means that it wont kill your pet. Great, but skin irritations are still very prevalent! Dogs make nearly constant contact between their feet, and the floor or soft furnishings, meaning they are more at risk of contact allergies on the feet, causing biting. Environmental Products Navigating around environmental toxins can be extremely tricky. The vast majority of councils in the UK tend to spray weed killer on the streets. These are just one of the environmental products which can contribute to paw biting. Others include patio cleaners, professional astroturf cleaners, grit/antifreeze, and many others. Washing paws after walks is a great idea to help reduce the risk of these toxins affecting the comfort of the dog’s paws. Yeast Yeast tends to have a very familiar symptom, along with the paw biting; a rusty colour on and around the toes. Yeast has two pathways – from the gut, and purely on the skin. Most yeast we see is down to an unhealthy gut, which allows for the overgrowth of candida, however, less commonly dogs may get Malassezia; which is a yeast infection on the skin. Candida Candida is a fungus which occurs naturally on the skin, and in the gut. When it is present in the correct amount, it’s a healthy part of a well-functioning microbiome. The issue comes when candida out competes good bacteria – this leads to a yeast infection. This predominantly occurs in the small intestine, and is aptly named Small Intestine Fungal Infection (SIFO). Overgrowths of candida can be down to exposure to the aforementioned toxins, poor gut health (and therefore a weakened immune system), allergies and intolerances, and antibiotics. As antibiotics not only attack bad bacteria, they also attack the good bacteria, which allows for the growth of fungi such as candida. As yeast thrives on sugar, its important to cut out any high carb, starchy, and sugary foods. Dry food can contain anywhere between 30 and 70% carbohydrates! This means that feeding a balanced fresh food would be the best option. It is also very important to keep on top of, or get to the bottom of allergies and intolerances; running an elimination diet, and healing the gut with mucilage herbs and probiotics is usually the winning combo when getting to the bottom of intolerances. Vaccines, some types of fish such as tuna, and even tap water are contaminated with heavy metals – yeast also thrives on heavy metal exposure, so it’s also important to not use such products, and use filtered water. Working on gut health is very important – you may find our Gut Guardian supplement useful! Findings Here Findings Here Malassezia Folliculitis Affecting only the skin, Malassezia Folliculitis is the skin-specific species of yeast fungus. Often called Fungal Acne, Malassezia causes acne-like pimples on the skin due to the yeast infecting hair follicles. Malassezia can be harder to treat than candida, but thankfully, rarely affects the paws. Findings Here Findings Here You can fund out more about yeast in our blog here! Allergies and Intolerances Unbeknownst to many, allergies and intolerances are very different from one another, and intolerances are often mistaken for allergies. Intolerances are the digestive inability to break down certain foods, specifically proteins. The inability to digest proteins properly, causes intolerances to develop. They can be worked on and improved through gut-work using mucilage herbs, and probiotics such as our Gut Guardian supplement. Allergies are much more severe, and are down to immune modulation – true allergies cannot really be improved. In some cases, allergies are life threatening. An interesting fact, is that in food reactivity cases, on average 10% are true allergies, whereas 90% are intolerances. Food Food allergies and intolerances can affect paw biting, due to poor gut integrity which causes a histamine response by the body. When the body reacts to a sudden influx of histamine, one of the most common symptoms is itching. Irritation can, and often does happen all over the body. Red sores, constant scratching, restlessness, and frustrated panting can all show your dog is itchy. Paw biting is one of these common symptoms too – this shows the dog’s paws are itching, as part of the immune response to foreign particles in the bloodstream. Contact Contact allergies
Haematomas are one of the more common soft tissue issues we tend to see here at My Pet Nutritionist. The most frequently occurring Haematoma is the Aural Haematoma; a subdermal haematoma found on the ear, however these benign masses can also be found on the spine, the brain, the heart, or anywhere else in the body. This blog will look at some of the types of haematoma, symptoms, diagnoses, and how we can offer support when a dog has a haematoma. What is a Haematoma? Similar to a bad bruise, a haematoma is a collection of blood which has formed in an organ or body tissue, typically as a result of a ruptured blood vessel. Haematomas are often mistaken for a tumour, due to their tumour-like appearance. Haematomas present as hard, raised lumps, which are usually very painful, whereas a bruise is a flat, malleable discolouration of the skin which may be a little sore to the touch. Where bruises usually heal with no additional medical help, haematomas sometimes require surgical intervention, such as drainage as they can become so large, they can cause life threatening issues due to the inability to get sufficient blood flow to a certain area, or they may become infected. Types of Haematoma Let’s discuss a few of the more common haematomas, their symptoms, and causes. Aural Haematoma As previously mentioned, haematomas of the ear are the type we see most often. These usually present on the flap of the ear (scientifically known as the ‘pinna’). When the blood vessel in the ear is damaged, blood leaks into the area between the skin and cartilage of the ear, which causes a pool of blood to form. Depending on the severity of the bleed, the ear position may change as the pool of blood may interfere with the muscles in the ear, as well as the ear canal, due to swelling. Aural Haematomas are extremely painful to the touch, so avoid touching the ear too much so as not to cause pain and distress in your pet. Aural Haematomas happen when there’s trauma to the ear, usually caused by dogs shaking their heads during ear infections and ear mite infestations, or by excessive itching of the area in allergy dogs, or dogs with insect bites on the neck or head areas. Aural Haematomas are also fairly common in dogs who have been a victim of a dog attack when the dog bite hasn’t broken the skin. Studies suggest that Aural Haematomas are not as a result of autoimmunity, but could be caused by other immunological events, such as infection control in the presence of a pathogen, or histamine responses in the presence of an allergen. Findings Here Aural Haematomas can heal on their own, however they often result in ‘cauliflower ear’ – the pinna appears crumpled/intricately folded. The science behind this malformation of the ear following a haematoma, is down to the substance released during the trauma of the area. The fluid which leaks between the cartilage and the skin, is a fibrotic rich serum. When the haematoma heals, the body reabsorbs the leaked fluid, which leads to fibrosis in the pinna. When fibrosis occurs, the fibrotic tissues in the area contract, which causes the folds often seen. Findings Here Haematomas on the Brain Haematomas can be found on the brain, and can be Subdural or Extradural Haematomas. Subdural Haematomas are often associated with underlying brain injuries, whereas Extradural haematomas are usually down to skull fractures, and damage to a meningeal artery (the main blood supply for the brain). These are generally the most dangerous type, and have a variety of symptoms, including vomiting, lethargy, paralysis on one side of the body, confusion, and uneven pupil sizes. In cases where the haematoma is located on the brainstem, upper (cervical) spinal pain is common too. Haematomas on the brain are most commonly seen following trauma to the head from vehicle accidents. Findings Here Findings Here Findings Here Findings Here Studies show Cerebral Haematomas can also be caused by an infestation of French Heartworm (Angiostrongylus vasorum). This is just one of the ways the parasite causes major neurological problems. Findings Here While the prognosis for those diagnosed with any subdural haematoma may be a scary one, there is evidence to suggest a veterinary treatment plan is available, and successful for the condition. A study carried out on a large breed dog, kicked in the head by a horse, shows a full recovery within 15 months of intercranial surgery, antimicrobial therapy, and corticosteroids. Findings Here Spinal Haematomas Spinal Haematomas can be present for a number of reasons, and can be debilitating during recovery. Intervertebral Disc Disease (IVDD) patients may suffer from a spinal extradural haematoma, as a result of trauma during the herniation of the affected vertebrae. Spinal compression caused by Pneumorrhachis (air bubbles stuck in the spine) can also lead to haematoma formation. Findings Here Findings Here Findings Here There is also evidence to suggest that bites from venomous snakes may also contribute to haematoma formation on the spine. The other most common cause of spinal haematoma is trauma during spinal surgery. Findings Here Findings Here Tracheal Haematomas Haematomas in the trachea can cause acute (sudden) respiratory difficulties/blockages, due to the airway being blocked by the raised haematoma. These are most commonly discovered following surgery, and are caused by the intubation tube used. When the wrong type, or size of intubation tube is used, or the tube is not handled carefully, trauma occurs in the trachea which can cause bruising, or damage to the blood vessels, resulting in the formation of haematomas. Trauma following neck surgery may also contribute to the formation of Tracheal Haematomas, but there are studies to suggest this is the case, and others to suggest it isn’t the case so more research needs to be carried out to determine a definitive answer. Findings Here Findings Here Findings Here As with other types of haematoma, trauma from non-surgical events can also cause haematomas. A
The term allergy is commonly used within the pet nutrition realm. Whilst allergies to cleaning products or compounds in the environment do occur, the true incidence of food allergy in dogs is quite low. Whilst allergies do exist, we tend to see a higher number of intolerances, so what’s the difference and do we need to approach them differently? Let’s take a look at allergies and intolerances in dogs. What is a food allergy? A food allergy or other allergic response is caused by an IgE antibody reacting towards that allergen. IgE binds to mast cells to promote histamine release. In short, the immune system has sensed the particle and wants to get rid of it at all costs. You’ll know the hallmark signs of an allergy if you are unfortunate to suffer with hay fever, but the common symptoms of an allergy include: Itching Hives Swelling Coughing Sneezing/wheezing Watery eyes Anaphylaxis What is a food intolerance? In the case of a food intolerance, we tend to discuss it in terms of IgG. IgG is the work horse antibody; it is the soldier, the memory antibody. This is what gets drafted when your dog is exposed to something they have already figured out a response to. Symptoms usually begin within a few hours of eating the food that your dog is intolerant to but it’s important to note that symptoms can be delayed by up to 48 hours and last for hours or even days, making the offending food especially difficult to pinpoint. IgG’s are mostly raised from the barrier mucosa in the digestive system. After a meal, there are both antibodies and complexes of food antigens bound to specific IgG’s. These complexes are quickly cleared by the reticuloendothelial system. Clinical observations suggest that due to gut inflammation and permeability (leaky gut), the digestive system is unable to digest the proteins effectively which subsequently raises IgG response to certain foods. Chronic intestinal inflammations and permeability are related to and possibly responsible for food IgG sensitivity. A point to note is that 90% of food reactivity comes from IgG’s. Intolerances can be changeable, but allergies tend to be for life and only account for around 10% of food reactivity. The common signs of an intolerance include, and are not limited to: Poor growth in young pets Itching Vomiting Diarrhoea Flatulence Recurring ear issues Acid reflux SIBO Pain or discomfort Loss of appetite As you have gathered there is a glitch in immune function in both allergies and intolerances, but we must also consider the function of the digestive system when we are tackling intolerances. It’s important to note that IgG’s come in different categories but to keep it simple, they are generally defined as cyclic or fixed. A common IgG reaction is cyclic and can take around 3 months to disappear/change. A fixed Intolerance tends to linger for longer and can take around 6 months to disappear/change, what this means is there is no quick fix to support your dog who suffers with intolerances, we’re in it for the long haul. How to Support the Intolerant Dog First of all, we prime and reset the digestive system, and this includes starting with an elimination diet, but also includes gut healing and immune balancing protocols. We follow the 4 R’s. – Remove – carry out an elimination diet. Raw or lightly cooked is the best way to do this. Cooked foods can take pressure off the digestive system, which in these cases is beneficial. Start with novel proteins (proteins your dog’s immune system has not seen before) for example, horse, ostrich, kangaroo and hare are generally well tolerated. Horse is lean too, so a great option if digestive function isn’t where it needs to be, yet. Feed this novel protein for 4-12 weeks. Ideally if you land on a novel protein that helps the itch/digestive discomfort or doesn’t make it any worse, we recommend remaining on this protein for 12 weeks. As we noted this is the time it takes for an intolerance to change. We then introduce other novel proteins – but at no more than one per week and sticking to single source. Treats need to match too! If there are signs of intolerance, then remove that protein and go back to a protein you believe is best tolerated. Notice that it’s called an elimination diet, and not an elimination lifestyle. The overall aim is to eventually maintain a strong diversity in the diet as we know this supports optimal gut health. We would be looking to reintroduce more common proteins as time went on – but this takes time. We also practice the same process when reintroducing any fruit or vegetables – one at a time, over time. It can also be worthwhile opting for a low-histamine approach when reintroducing too. – Repair – support immunity and gut healing. Include ingredients like slippery elm, de-glycerised liquorice, glutamine, and N-acetyl-glucosamine. It is also important to consider how existing medications are affecting gut healing for example, steroid use impairs intestinal absorption which is linked to several gastrointestinal dysfunctions. But, because of their anti-inflammatory and immunosuppressive activities, they are often prescribed in cases of allergies or intolerance. Findings here – Restore – optimise microbiome health As the microbiome is key in the development of the immune system, supporting this is essential. However, the introduction of specific pre and probiotic foods or supplements is sometimes best left for a few weeks into your plan, especially when carrying out an elimination diet. There may be probiotics on the market that contain protein sources not indicated on the label – always check with the manufacturer what is contained in their product and indicate that you are carrying out an elimination diet, so you need accurate information. – Replenish Indigestibility of food proteins can also contribute to their antigenic nature, so consider any long-term medication use including proton pump inhibitors which affect gastric acid secretion. Ensuring HCL, pepsin and digestive enzymes are in good
For some dogs, their sensitivities can be year-round. In this instance we are considering their exposure to environmental toxins, the food they eat and how their immune system matured and subsequently functions. For other dogs there is a direct correlation with the time of year. Whilst the sun is shining and anything feels possible for us humans, it can be a miserable time for our seasonally itchy dogs. Many dogs have a sensitivity to grass sap and keeping them off the freshly mown lawn for a couple of days can help keep pesky irritation at bay, but some allergies are a little more complicated. As always, we are available to help you manage any chronic irritation suffered by your dog, but we thought we would give you some of our top tips that can come in handy when managing your seasonally itchy dog. If you would like to understand more of the mechanism of an allergy or sensitivity, then check out the wealth of information in our other blogs: Why Do Allergies in Dogs Develop? Does My Dog Need an Allergy Test? Your Pet’s Immune System Why Allergies and Itching Have Become Such an Epidemic Now, on to our top tips: 1) Support the Gut! As you will know if you read our articles on the immune system and the lymphatic system, in the gut you will find GALT, or gut-associated lymphoid tissue. The digestive tract is heavily laden with lymphocytes, macrophages and other cells that participate in immune responses. An allergy, in essence is an immune response gone bad, so we need to support immune function and that includes the part of the immune system found in the gut. In addition, in a poor functioning digestive system, rogue particles can end up leaking through the barriers. This can be in cases of periodontal disease (bacteria getting into the blood stream from plaque formation) and damage in the tight junctions in the intestinal tract. When this happens, the immune response is called to the area of the rogue particle to get rid of it. These systemic responses can lead to hypersensitivity, leaving the immune system a little too eager to do its job on a body wide level. It is therefore essential to support the barriers in the mouth; ensuring good dental hygiene but also to support the barrier of the gut. Look to lovely gut healing ingredients such as Slippery Elm, De-Glycerised Licorice, Glutamine and N-Acetyl Glucosamine. 7 Steps to Optimal Gut Health for Pets Gut Guardian 2) Consider the overuse of pharmaceutical flea and worm treatments! Whilst there is sometimes a place for the use of pharmaceutical products in high burdens of parasites, we would always advocate the use of wormcount kits to establish any burden of worms before treatment and also the use of flea repellent products over any spot-on or tablet flea treatment. The overuse of certain pharmaceutical products can place an unusual burden on many pathways in the dog’s body, compromising optimal function. It also pays to consider how often you vaccinate your pet. Vaccinosis: Damage Vaccinations Can Cause Your Pet Does My Pet Need to Detox? Natural Flea and Worming Treatments Supporting the liver and lymphatic system is essential during these times, Liver Guard can be great in this instance. Liver Guard 3) Limit Stress! Mast cells have a key role in allergic response; when they detect a substance that isn’t liked by the body, they release histamine and other chemicals into the bloodstream. Histamine makes the blood vessels expand and the surrounding skin itchy and swollen. This is known as degranulation and what’s super interesting is that stress can result in degranulation too! This may explain the red face you feel as you are getting stressed, or if you break out in hives when you’re facing a particularly stressful time in work. If you are working to tackle allergies in your dog, then it is important to remove as many stress triggers as possible, for your dog, but also you. There is this idea of co-regulation of species, that dogs can pick up when we are stressed and we’ll admit, there is nothing more stressful than seeing our dogs suffer and feeling that we aren’t getting anywhere with fixing it! It can pay to establish our own levels of stress when we are managing a poorly pooch. Check out our perceived stress scale in the following blog to help you understand your own stress levels. 5 Tips For Dealing with a Fussy Eater Calm Complex br] 4) Rinse your dog, but not wash! If you suspect your dog may have sensitivities to certain grasses or pollen, rinse their paws, undercarriage, and chest after walks. You can also wipe their muzzle, ears, and face with a damp microfibre cloth when you get home too. But avoid over-shampooing your dog. Whilst you may opt for non-toxic products, washing can skew the microbiome found on the skin of your dog and this provides a first line of defence for the immune response. The skin has its own community of microbes that can engulf and destroy pesky ones before they have chance to cause problems; frequent bathing can alter this community. So, rinse your dog to remove potential irritants, but keep the shampoo for special occasions, like fox poo events. Your Puppy’s Microbiome 5) Essential Fatty Acids Are Just That! Allergies and sensitivities are an immune response and inflammation is the hallmark of an immune response. Inflammation is a necessary process in the body, but we need just enough to solve the problem at hand. We have compounds necessary to kick start the inflammatory response, and we have compounds that reign it back in again. What we often find is that there are more compounds around to perpetuate inflammation, and not enough to reign it back in! Therefore, it can help to fill up on foods to regulate the inflammatory response. Omega-3 is a fatty acid that has regularly been linked inflammation regulation.
Possibly one of the most common ailments that we find in the dog world – some dogs just seem to react to everything! But, if we know how allergies and sensitivities develop, is it something we can tackle? Let’s take a look and consider some top tips to support your dog’s health. What is a dog allergy? An allergy is an unnecessary immune response to an innocuous substance. True allergies are often fatal. More often than not we are faced with sensitivities – which are still an immune response. What is the immune system? The purpose of the immune system is to defend itself and keep microorganisms like bacteria, viruses, and fungi out of the body and then destroy any if they happen to get in. It has three lines of defence. The innate immune system provides the first line of defence; broadly divided into physical/chemical barriers. The physical barriers include the skin and the lining of the digestive and respiratory tract. You can think of the body like a sausage; the skin, keeps everything in, but also things out. Chemical barriers include tears and saliva along with gastric acid. But also, the microbiome – which is the community of microbes found in the mouth, lungs, gut and on the skin. We then have the innate immune system – which is for want of a better phrase a row of white blood cells (and other participants) that engulf and destroy invaders. The third defence is acquired or adaptive immunity – this is the memory bank. The cells involved in this response help the body remember antigens that it has encountered before – so it can mount a quicker response before the harmful pathogen causes any damage. The immune system is trained to recognise its own cells as self and leave them to do their jobs. It is trained to recognise anything that isn’t self and attack it. When it works, it works brilliantly and, well, us and our dogs survive. But, it can get a little too enthusiastic and start responding to things it doesn’t really need to. This is what we see as autoimmunity, but also allergies and sensitivities and there are a number of reasons for this. Allergies and Sensitivities First of all, we may be dealing with an immature immune system, and this all starts back in puppyhood. When we talk about immune responses, we tend to reference Th1 and Th2. They are both necessary responses, but a Th2 response is more commonly associated with allergy. During pregnancy, a strong Th2 response is present to reduce the risk of miscarriage. What this means is that puppies are born with a Th2 dominance. This then needs to be balanced and the way in which this occurs is through microbial exposure. This is what we know as immune tolerance – the immune systems develop through exposure to controlled challenge. The immune system is like a computer; it has software, but it needs data. The microbial ecosystem in various mucosal sites is important for the development of the immune system. The young gastrointestinal tract is colonised soon after birth by a variety of commensal bacteria that influence the development of the immune response both in the gut and systemically. The mucosal immune system in the gut must avoid adverse immune responses to dietary antigens and commensals in the new microbial ecosystem while remaining able to mount an effective response to pathogenic organisms. In an ideal world, our pets will develop a heathy immune system, and they will have sufficient immune tolerance but also eliminate threats when necessary. But we don’t always live in an ideal world. Gut Guardian br] So what else can cause issues with immune responses? Often allergies and sensitivities are associated with poor barrier function; so there may be damaged or broken skin, a poor microbiome, or damage to the integrity of the gut. Think of it like an army. If you have a row of soldiers who are standing shoulder to shoulder, you stand a good chance against the enemy. Once soldiers start falling, opportunities arise for the enemy to get through. When skin is damaged, antigens spot their opportunity and sneak in through the gaps. The same occurs in the gut. Cells sit tightly together, but when cell integrity fails, under digested food particles and pathogens see their opportunity and sneak out into circulation. The immune system spots these particles – realises they shouldn’t be there, so mounts a response. Inflammation is a key part of this response. The issue is when the barrier remains compromised, more particles sneak through and so you end up in a chronic state of inflammation. Barrier dysfunction can occur for a number of reasons: Genetic glitches Microbiome dysbiosis Long-term use of medication Toxins Environmental exposure Detoxification Pathways The more inflammatory compounds you have in the presence of a response, the more anti-inflammatory compounds you will need to counter this response. There will also be a heightened need for compounds that break down inflammatory molecules like histamine. Those suffering with allergic disease often have a higher baseline of histamine, and so clearance of this is important too. What this means is that detoxification pathways need to be running as smoothly as possible. Liver Guard Detoxification of dietary histamine normally occurs in intestinal epithelial cells via the enzyme diamine oxidase (DAO) as well as histamine-N-methyltransferase (HNMT) in the liver. What’s interesting is that there are polymorphisms in the genes that code for the DAO enzyme, but certain medications, including over the counter products are seen to inhibit the activity of DAO enzyme too. They include: Analgesics – morphine, NSAIDs Antiarrhythmics Antibiotics Antifungals Antimalarial Diuretics Motility agents Muscle relaxants Vitamins – ascorbic acid, thiamine In addition, detoxification pathways in general are nutrient demanding and they also produce a high number of free radicals. Sufficient levels of key vitamins and minerals like vitamin A, C, E, B1, B2, B3 and iron, along with cysteine are essential. Does My Pet Need To
We sometimes talk about intolerances and allergies like this is the only thing that can cause your cat or dog’s itching. There can be so many reasons, layered reasons and some more serious than others. Here we explore some of the undetected and misdiagnosed reasons for your dog being itchy. Adrenal function The adrenal glands are located just in front of the kidneys. You will recognise them from when we discuss the stress response more often than not. The adrenal gland has 2 parts—the cortex and the medulla. The adrenal cortex is subdivided into 3 layers, and each layer produces a different set of steroid hormones. The outer layer produces the mineralocorticoids, which help regulate sodium and potassium salts. The middle layer produces glucocorticoids, which are involved in metabolising nutrients and reducing inflammation and immune responses. Finally, the inner layer produces sex hormones such as oestrogen, progesterone, and androgens. The adrenal medulla plays an important role in response to stress or low blood sugar levels in the body. It releases adrenaline and noradrenaline, both of which increase heart rate and blood pressure, increase blood sugar and slow digestion; the hallmark responses when us or our dogs are exposed to a stress trigger. The adrenal glands are part of the endocrine system – which is simply a system of glands that release chemical messengers called hormones. The endocrine system influences almost every cell, organ, and function in the body. So, if there is any issue in any part of it, things can start to go wrong. The two most common ways in which adrenal glands cause health issues are by producing too little or too much of certain hormones, which leads to hormonal imbalances. Hyperadrenocorticism (Cushing’s Disease) due to an excess of cortisol production frequently causes dogs to itch, lose hair, have thin skin with dark pigment, drink excessively and have recurring skin problems. But this raises another point, even if there are no physiological issues with the adrenal glands, high cortisol levels due to daily stress can also lead to itchy skin! Thyroid Function We’ll continue with the hormones for a minute and look at thyroid function. The thyroid is a butterfly shaped gland found in the neck. One of its main functions is to produce hormones to regulate the body’s metabolism, the process that turns food into energy. This too can produce too many hormones, or too few. These conditions are known as hyperthyroidism and hypothyroidism respectively. Hypothyroidism Hyperthyroidism Hyperthyroidism in Cats Skin issues are regularly noted in times of thyroid dysfunction, and this includes itchiness. Kidney Function Intense itchiness often accompanies late-stage kidney disease, and whilst the jury is out on the exact reasons behind it, it is thought that it’s relating to the build up of toxins in the body. This leads us nicely into the same itchy symptoms associated with early-stage liver disease, and this is considered for similar reasons. Detoxification Detoxification is carried out by a range of mechanisms, and this comes in particularly handy if one pathway is overwhelmed, another can pick up the slack. The Liver The liver neutralises a range of toxic chemicals, both those produced internally (waste from used hormones or neurotransmitters for example) and those from the environment, like air pollution, pesticides, and food additives. It does this by filtering the blood to remove large toxins, synthesising, and secreting bile and lastly enzymatically disassembling unwanted chemicals found in the body. Liver Guard Enzymatic Detoxification This enzymatical detoxification occurs in three phases. Phase I directly neutralises chemicals and changes them into new metabolites. These are then processed by phase II enzymes. This is known as the conjugation phase, which in short, liver enzymes attach small chemicals to the toxin. There are many ways in which this is done, it all depends on the type of chemical the liver is trying to manage. Phase I results in high levels of reactive oxygen species so antioxidant levels are key in modulating potential damage. Phase II is nutrient demanding and sufficient levels of key vitamins and minerals like vitamin A, C, E, B1, B2, B3 and iron are essential. Phase III is the elimination phase. For optimal excretion of toxins through the digestive system, gut health is vitally important. Maintaining the mucosal barrier is key for gut health along with supporting motility. The kidneys will also filter and process toxins from circulation, excreting them as urine. The skin also forms as an elimination pathway. This is why detoxification issues can result in skin issues. In cases of liver disease, it is considered that bile salt deposits under the skin, which results in itchiness. The most important thing to do to support detoxification is to avoid exposure in the first place, so consider how much you and your dog are exposed to: Pesticides Heavy smoke Phthalates Mould Medications like steroids, antibiotics, and painkillers Heavy metals Cleaning products Air fresheners Eating foods cooked at high temperatures (most commercial dry foods) This list is not exhaustive, but it is a place to start. This mechanism also applies to vaccines. There is increasing evidence that over-vaccination is associated with the development or aggravation of immune-mediated disorders and chronic diseases in individual pets that are genetically predisposed. The primary role of the immune system in dogs is to protect against foreign invaders, or abnormal cells that invade or attack. The immune system must distinguish between self and non-self. Substances that stimulate a response are antigens. These can be contained within bacteria, viruses or microorganisms or cancer cells. They may also exist on their own, like pollen or food particles. There are three lines of defence, physical barriers, nonspecific immunity, and specific immunity. But the immune system does not always function properly, it can be underactive and overactive. An underactive system puts the animal at risk of infection, but an overactive immune system can attack parts of its body that it misidentifies as being foreign. This is what happens in autoimmune conditions. The immune system can also overreact
Amongst the foods marketed for pets, grain free is sitting front and foremost. Whilst we specialise in a range of health issues here at My Pet Nutritionist, we also consult on the most appropriate diets for pets. One of the questions we have been asked, does my dog need a grain free diet? Well, we see huge benefits to a whole or cooked fresh food diet, which is technically grain free, but we know this isn’t what you mean, so let’s take a look at where grain free diets came from and how they have found their way into many homes around the world. Grain Free Diets The concept of a grain free diet likely came from human literature. Grains are in fact a staple in many traditional diets, but a number of books appeared on bookshelves resulting in people cutting this food group out. Grains include wheat, spelt, rye, corn, millet, rice, sorghum, and oats. You’ll notice that both gluten and non-gluten grains are included. In addition, many people opted to cut out products derived from grains like rice syrup or high-fructose corn syrup (which is actually great!). There were a number of reasons for the demonisation of grains. Firstly they were thought to contribute to inflammation in the body, and therefore be a causative factor in many inflammatory conditions. This could be due to the lectin content found in grains. Lectins are often described as an antinutrient and as they are found in potatoes, beans, lentils, peas, soybeans, nightshade vegetables and you guessed it, grains. Lectins are carbohydrate binding proteins present in most plants, especially seeds and tubers like cereals, potatoes, and beans. Their original purpose was protection. They would produce an inflammatory response in the animal that ate them – so they wouldn’t eat them again. Humans and Dogs are largely unable to digest them, but friendly bacteria in the gut can lend a hand. At high dietary levels, it is thought that lectins cause damage to the structure of the brush borders of the small intestine. In lectin fed rodents, the mucosal membrane in the small intestine was stripped, compromising the gut integrity. This compromise has also been linked to abnormal bacterial proliferation. Findings Here Furthermore, some bacteria responsible for urinary tract infections contain lectins specific for the sugar mannose and use these lectins to bind tightly to mannose-rich tissue in the bladder walls – therefore initiating infection. D-mannose supplementation provides a decoy for these bacteria. Lectins also cause discharge of histamine from gastric mast cells which stimulates acid secretion – and as you know, we obviously need stomach acid, but in the right amounts – not too much, or too little. In addition, animal and cell studies have found that active lectins can interfere with the absorption of minerals, especially calcium, phosphorus, and However, lectins are most potent in their raw state, so cooking can inactivate most lectins. They are also water-soluble, so soaking also removes them too! Grains have also been linked to: Anxious and depressive behaviour Chronic pain However, most studies to date have considered these issues alongside gluten containing grains. Researchers have therefore concluded that the issue may in fact be relating to gluten as opposed to the grain. Grain free diets have been linked to weight loss, reduced inflammation, and modulated blood sugar levels. However, to fully understand the role of grain free diets, it’s pertinent to pick this apart a little further. Many grains contain a carbohydrate content, when grains are refined and processed, like those found in many commercial foods, they become a calorie-rich but nutrient poor food. With the removal of the grain, by default, the calorie content is reduced. This same premise applies to inflammation. It is well established that refined grain intakes have been positively associated with risk of metabolic diseases as well as with inflammatory protein concentrations. Refined grains are milled, a process that strips out both the bran and germ to give them a finer texture and longer shelf life. The refining process also removes many nutrients, including fibre. Refined grains include corn flour and white rice. Whole grains on the other hand haven’t had their bran and germ removed by milling; therefore, all of the nutrients remain intact. Whole grains are sources of fibre and other important nutrients, such as selenium, potassium, and magnesium. Whole grains include millet, bulgur, buckwheat, barley, and oatmeal. This is relevant when we consider how grain free diets have been linked to modulating blood sugar levels. Grains are naturally a source of carbohydrates. As we know, when carbohydrates are ingested, without naturally occurring fibre, they are digested very quickly, and pass into the blood stream. This results in a spike in blood sugar, which insulin must come and manage. Refined grains are devoid of fibre. Whole grains on the other hand are rich in fibre which may help stabilise blood sugar levels. The take home here is when we are looking at the benefits touted in grain free diets, we must consider the grains that are being referenced. Grain Free Diets and Dilated Cardiomyopathy You will have come across the FDA link between grain-free dry dog foods and dilated cardiomyopathy (DCM). The issue is suggested to be related to a taurine deficiency. Cats and humans are among the few mammals whose bodies do not make taurine, and therefore must obtain it from their diet. In humans, taurine deficiency is rare because taurine is common in meat and fish food products. In the 1970’s, Quinton R. Rogers of UC Davis showed that a taurine deficiency could cause degeneration of the retina in cat’s eyes. Kittens born to taurine deficient mothers are often blind and show many abnormalities such as impaired gait. For this reason, in the 1980’s new cat feeding guidelines were introduced, stating a minimum level for taurine in cat food. But, in later years it was also found that taurine plays a role in regulating calcium entry into heart tissue every time it beats. Researchers
