Everything You Need to Know About Your Dog’s Microbiome!

Here at My Pet Nutritionist, we know that a healthy gut microbiome is the most important aspect to keeping your dog healthy all round! There is so much to learn about the gut microbiome – what it really is, what it consists of, what other parts of the body it interacts with, and what happens when it’s not in tip top condition. Many of our readers will notice that most of our blogs mention the microbiome, so this blog post is a full round up of everything gut microbiome related, in one easy read! What is the Gut Microbiome? Every dog has a gut microbiome. It’s one of the most important parts of your dog in terms of digestion and overall health, from joints to skin, to the brain and immunity. The microbiome is a community of microbes, including good and bad bacteria, viruses, and fungi. The gut microbiome is very carefully balanced. Some of the microbes found in a healthy gut microbiome are ones we would typically class as ‘bad’ which have health conditions associated with them, including bad bacteria such as Salmonella, and Clostridia. Viruses and Fungi are typically classed as ‘bad’ microbes too, but are still part of a healthy microbiome. Good bacteria such as Lactobacillus, Bifidobacterium and Enterococcus are all found in abundance in the healthy canine gut microbiome – these beneficial bacteria are found in high enough numbers to outweigh the negative impact of the bad microbes found in the gut. A healthy gut microbiome means the ‘good guys’ outweigh the ‘bad guys’. Health problems begin to emerge when the gut microbiome is knocked out of balance, allowing for gut dysbiosis to occur. Gut dysbiosis can lead to a host of health problems including reduced skin and joint health, increased digestive issues, and prominent or mild negative behavioural changes. Findings Here Findings Here Interactions Between the Gut Microbiome and the Rest of the Body The health of the gut microbiome is a huge part of overall health – but why is this? You may be wondering how gut health could impact so many other parts of the body, so let’s take a closer look at these! We can look at the gut as a ‘roundabout’. Roundabouts have multiple exits – these ‘exits’ stemming from the gut are collectively called Axes; and these link to other parts of the body to form a two-way pathway/link from the gut. The main axes are: The Gut-Skin Axis: this pathway connects the gut to the skin, and the skin to the gut. If we start at the gut and work our way to the skin, we can see that poor gut health can cause or exacerbate skin conditions. Going to other way; from skin to gut, we unfortunately have the risk of gut microbiome damage caused by external exposure to toxins, whether they’re from laundry detergents, household cleaning products, external flea and tick medications, or other environmental toxins. The Gut-Joint Axis: this pathway connects the gut to the musculoskeletal system, and the musculoskeletal system to the gut. An imbalance in the gut microbiome can be connected to poor joint health, especially in cases of osteoarthritis due to the increase in inflammation around the joints. In a poorly balanced gut, there is often an increased risk of pro-inflammatory cytokines and inflammatory metabolites being produced, which are the main cause of poor joint health in dogs. The Gut-Brain Axis: this is the bidirectional pathway between the brain and the gut. This pathway has connections both physically, and chemically. In terms of physical connections, the Vagus Nerve is the main avenue for carrying signals between the two locations. Chemically, the healthy gut produces neurotransmitters and hormones, which move between the brain and gut. Mood, response to stress, and digestion are three of the main roles of the gut-brain axis. It is also important to note that around 70-80% of the immune system is found in the gut! Keeping the gut microbiome healthy, and perfectly balanced means the immune system, and therefore overall health of an individual remains stable. Findings Here Findings Here Findings Here Findings Here What Happens When the Gut Microbiome is Unhealthy? When the Gut Microbiome is unhealthy, a host of health conditions can occur. As previously mentioned, an unhealthy gut microbiome is unbalanced; and this condition is called Gut Dysbiosis. Gut Dysbiosis occurs when the ‘bad microbes’ outweigh the ‘good microbes’. Here’s some health concerns that we see a lot in those with an unhealthy gut microbiome: Food sensitivities: when the gut microbiome is unbalanced, food sensitivities are common due to increased gut permeability; known as Leaky Gut. When the gut integrity is poor, food particles leak into the bloodstream which encourages the body to create an immune response, presenting as food sensitivities. Yeast: yeast cells are naturally present in the gut; they’re called Candida. When Candida is present, and there’s not enough of the good microbes to keep these in check, a yeast infection will often occur. Symptoms include rust coloured paws, ears and groin, cheesy smelling feet, and itching among others. Digestive problems: digestive upset including diarrhoea and vomiting is common in those with an unhealthy gut microbiome, due to the abundance of ‘bad’ microbes and a lack of ‘good’ ones to keep the effects of the bad ones at bay. Many dogs also suffer with Small Intestine Bacterial Overgrowth (SIBO) which contributes to these symptoms. Bad breath: a lot of owners assume their dog’s bad breath is caused by poor dental hygiene, however this is often not the case. Bad breath can emanate from the gut, in those with poor gut health. When the gut microbiome is unbalanced, the overgrowth of harmful bacteria in the gut results in the production of VSCs; Volatile Sulphur Compounds, which cause bad breath. Inflammatory Bowel Disease (IBD): when the gut microbiome is unbalanced, inflammation occurs as a result. This inflammation often leads to chronic inflammatory conditions such as IBD. Other gastrointestinal conditions occur due to this too, however IBD
The Skinny on Gut Healing Herbs and Nutraceuticals in Pets

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
How to Choose the Best Omega Oil for Pets

Omega oils are one of the most important components of your pet’s diet, but with such variety of products on the market, aimed both at animals and humans, how do we know which to opt for? Here at My Pet Nutritionist, we recommend a variety of different products from various different brands, and for many different reasons! This blog past aims to help you choose the right omega source for your pets, and explains how to tell one product from the next! What Are Omegas? Omegas are Fatty Acids with a huge variety of uses within the body. Cell membranes are partly formed by Omegas, which deems them an essential nutrient for all living beings. Brain and heart health are both aided by omegas, as well as weight management and cognitive development during puppyhood, and as seniors. Omegas also control part of the body’s inflammatory response, making them useful for joint health, as well as aiding the management of, prevention of, or treatment of many health conditions. Omega Fatty Acids come in three types: Omega 3 and Omega 6 fatty acids are both classed as ‘essential’ nutrients Omega 9 is classed as non-essential but is beneficial to include in the diet So how do the three types of omegas differ chemically? Each different type of omega has not only a different chemical structure, but they have a different amount of saturation of fat. Let’s take a look at their differences a bit more closely. Omega 3 Fatty Acids are ‘polyunsaturated’, which means there is more than one unsaturated carbon bond. In a diagram of chemical structure, you will see two or more ‘double bonds’ between carbon atoms, with a hydrogen atom missing. These polyunsaturated fatty acids cannot be produced by the body, and must be consumed in the diet. Omega 6 Fatty Acids are also ‘polyunsaturated’, however two of the Omega 6 Fatty Acids are able to be produced by the body, leaving the third needing to be consumed in the diet. Omega 9 Fatty Acids are ‘monounsaturated’, which means there is only one unsaturated carbon bond. In a diagram of chemical structure, you would see only one ‘double bond’ with no hydrogen attached to the carbon atoms. These fatty acids can be produced by the body, which makes them non-essential in the diet. We mentioned that some omegas play a role in the body’s inflammatory response, so let’s discuss which ones are inflammatory, and which are anti-inflammatory. Omegas 3 and 9 have some fantastic anti-inflammatory effects on the body, which aids joint health, and is also a contributor to the reduced risk of cancers. There is also one Omega 6 fatty acid which is anti-inflammatory. The names and health roles of these anti-inflammatory Omega 3, 6 and 9 Fatty Acids are as follows: Eicosapentaenoic Acid (EPA): Omega 3 Fatty Acid playing a role in general reduction in inflammation. Alpha-linolenic Acid (ALA): Omega 3 Fatty Acid playing a role in heart and immune health. Docosahexaenoic Acid (DHA): Omega 3 Fatty Acid playing a role in brain health and cognitive development. Gamma-linolenic Acid (GLA): Omega 6 Fatty Acid aiding the control of hormones. Oleic Acid (OA): Omega 9 Fatty Acid plays a large role in prevention of cancer and heart disease, and reduction of cholesterol. The other Omega 6 Fatty Acids are inflammatory, which negate the omega 3, and vice versa. It is very much a balancing act of omega 3 and 6 consumption, to receive the benefits of omega 6, but keep inflammation to a minimum. Linolenic Acid (LA): Omega 6 Fatty Acid which helps to prevent heart disease, keep a regular heartbeat, and potential to prevent blood clots. Arachidonic Acid (ARA): Omega 6 Fatty Acid which as an important signalling molecule, plays a huge role in the mediation of many cellular functions such as remodelling actin, a extremely important protein in some cells in the body, useful for protein-protein interactions. Findings Here Findings Here Findings Here Sources of Omega Where can we find these all important Omegas in order to add them into our pet’s diets? There are so many sources of Omegas, some good, some not so advisable. They are found in many forms, from fresh foods, to extracted oils which come in capsules, or in a large bottle, usually with a pump. There are meat based sources of omegas, and there are plant based sources of omegas. Some of the most popular sources of each type of Omega 3, 6 or 9 Fatty Acid we have discussed so far in this blog post, are: Eicosapentaenoic Acid (EPA): found in fatty fish and fish oils, as well as many algal oils. Alpha-linolenic Acid (ALA): found in flaxseed oil, chia seeds, walnut oil, perilla oil or oysters. Docosahexaenoic Acid (DHA): found in fatty fish , fish oils and algae oils, and eggs. Gamma-linolenic Acid (GLA): found in Hempseed oil, borage oil (to be given with caution, in small quantities only), and evening primrose oil (to be given with caution, and not to be given to epileptic pets) Linolenic Acid (LA): found in sunflower oil, some nuts, seeds, olive oil, flaxseed, avocado oil (though the amount here is low) and eggs. Arachidonic Acid (ARA): found in meat and poultry, particularly farmed. Oleic Acid (OA): found in olive oil, some fish oils, and some nuts. What to Look Out For When it comes to picking an omega source for our pets, as with anything, most of us want to make an informed decision to pick the absolute best for our furry friends! With such huge variety of Omega products on the market, how to we know what is best? How is one product different to another? As with many dietary additions, there are many qualities to look out for or avoid in different products. Not all products are equal in quality, so that’s where we come in handy – keep reading for pointers on selecting a source of omegas for your pets! Fresh Food Sources As with most things we
The Low Down on Furunculosis

Here at My Pet Nutritionist, we deal with a huge amount of dogs with skin complaints. One of the skin complaints we see fairly often is Furunculosis. As a recurring skin infection, there are things we can do to support the body; read on to find out how we can help. What is Furunculosis? Furunculosis is a deeply embedded infection of the skin, or deep rooted inflammation of the skin. it is a bacterial infection of the skin and soft tissues, and emanates from the around, and inside the base of hair follicles, reaching through the dermis, and into the subcutaneous layers of the skin (the layers just beneath the skin’s surface). Findings Here Furunculosis clinically presents as small, often pus-filled boils on, or just under the skin. There are a few types of furunculosis you may have seen mentioned in your time as a dog owner, so let’s take a look at the common ones! Anal Furunculosis What is it? Probably one of the most common types of furunculosis mentioned by dog owners, is Anal Furunculosis. As per it’s name, this is where hair follicles around the anus become infected, and chronically inflamed. Another name for Anal Furunculosis is Perianal Fistula. This is an extremely painful type of furunculosis, as well as being one of the most difficult to treat, and stop from recurring. Findings Here Causes Evidence suggests it’s an immune mediated disease, as there is a strong genetic association with one specific allele, and tests show upregulated cytokine expression causing T-cell infiltration. It also tends to mostly affect middle aged dogs. Findings Here Findings Here A zinc deficiency could contribute to the onset of furunculosis too; zinc deficiencies usually present clinically in the form of a variety of skin issues. Findings Here Genetic predisposition is a common cause of anal furunclulosis, including the following breeds: German Shepherd (most common predisposition) Beagle Labrador Various Bulldog breeds Old English Sheepdog Australian Shepherd Staffordshire Bull Terrier Findings Here Symptoms There are various symptoms of anal furunculosis, but many are similar to general anal gland troubles, and not obvious until the infected boils begin to show. Some signs and symptoms include: Scooting Licking/nibbling around the anus and base of the tail Change in posture Difficulty passing faeces Bloodied stool (bright red) Lethargy Potential weight loss Interdigital Furunculosis What is it? Many of our readers will likely have seen ‘interdigital cysts’ mentioned by other dog owners – these are incredibly common in our domestic dogs. ‘Interdigital cyst’ is the somewhat shorter, almost self-explanatory term for Interdigital Furunculosis. Interdigital means ‘between the digits’ – no, not number in this sense; but the toes. Inflamed and infected boils/cysts appear between the toes, causing pain and annoyance to the dog, due to infection showing outwardly, from the hair follicles in the area. Findings Here Causes Most causes of Interdigital Furunculosis are down to trauma to hair follicles present between the toes. A variety of things can cause this, which we will discuss below, but first, we will take a look at some other potential causes of interdigital cysts. Endocrine diseases such as Cushing’s Disease and hypothyroidism can contribute to problems internally with the hair follicles around the toes. Bacterial and fungal infections in the foot areas, including yeast (for which you can read more about in our blog here), and various strains of Staphylococcus infection, can cause the onset of furunculosis in between the toes. Now on to the trauma related causes! Paw licking is a huge risk factor for hair follicle trauma between the toes. Paw licking can be caused by food sensitivities, anxiety, pain in the area, or even due to compulsive neurological disorders. Foreign bodies like the dreaded grass seed may also cause both paw licking, and generalised inflammation of the toe area, and therefore increase the risk of interdigital furunculosis. The root cause of any paw licking must be found and treated as a matter of importance! The length of a dog’s paw hair can also cause trauma to the hair follicles. When the dog walks on his or her feet, the hair between the toes may rub, which causes skin inflammation, and leaves the hair follicles vulnerable to infection. Those with longer fur between the toes, may be at a much lower risk of hair follicle damage, as the fur helps protect the follicles. Dog breeds at a greater risk of interdigital irritation due to their shorter coat length include: Various Bulldog breeds Basset Hound Staffordshire Bull Terrier Pug Great Dane Boxer Boston Terrier Beagle The shape of the dog’s foot can also have bearing on it’s potential for the onset of Interdigital Furunculosis. Those with wider gaps between their toes leave the skin in between their toes open to irritation by the environment. Those who are overweight are also more likely to have poor paw conformation whereby their toes spread, causing potential for irritation of the interdigital hair follicles. Findings Here Symptoms Early signs of Interdigital Furunculosis are a little easier to spot than Anal Furunculosis. Generally, the area will become red to start with, and slight swelling may become apparent. In cases where a foreign body is present, oozing of the area may occur. This needs veterinary treatment right away. The dog will usually lick, nibble and or favour the paw(s) affected, which is a very strong sign of a paw ailment. Once fully established, the Interdigital Furunculosis will present as a large swelling between the toes, usually warm or hot to touch, and very red in colour. It can be a shiny texture on it’s surface too, due to the swelling of a specific hair follicle, and lack of fur on it. Findings Here General Furunculosis After Grooming What is it? While there’s generally no single reason for the onset of both Anal and Interdigital Furunculosis, generalized post-grooming Furunculosis has a clear trigger, and usually crops up 24-48 hours after a dog has been groomed. It can establish in any part of the body, particularly in
How to Help My Yeasty Dog

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
The Low Down on Keratosis

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
Hotspots: What’s Causing Them, and How To Help

Here at My Pet Nutritionist, we see lots of cases of Hotspots. Those seeing a hotspot for the first time can be worrying; those who deal with them regularly may feel overwhelmed, and frustrated at their regular reappearance. In this blog we will look at what hotspots are, how they happen, their link to gut health, and how we can support the body to heal them efficiently. What Are Hotspots? Hotspots are scientifically known as Pyotraumatic Dermatitis. Another common name for them is ‘Acute Moist Dermatitis’; this name gives more of a visual impression of what you can expect to see of a hotspot case. They present as red raw, moist areas of hairloss, and can happen on both dogs and cats. There is no specific place hotspots can happen on the body, and they tend to show up very quickly. Often confused with ringworm, hotspots are wet in appearance, and often more open/raw looking than ringworm. Ringworm also tends to occur in patches, as opposed to one single spot. Are they sore for your pet? Yes! Hotspots can be very sore for your pet, so it’s important not to leave them. You may notice increased itching and licking of the area, as well as potential behavioural changes due to pain. The sore my ooze liquid, particularly if the hotspot has become infected, which would also bring an unpleasant odour. The fur around the edge of the lesion may be matted. There is no correlation between age, sex or breed when it comes to the likelihood of s dog getting a hotspot. Findings Here What Causes Them? Hotspots are caused by bacterial overgrowth, or are secondary to another underlaying health issue. The biggest trigger for hotspots, is repeated itching of an area on the body. This can make hotspots a secondary health problem to allergies and intolerances, flea infestations and other insect bites, ear infections, grass seeds, stress and anxiety, and poor grooming husbandry when matts are close to the skin. The constant itching and licking of an area makes the perfect growth site for bacteria – moisture and warmth are bacteria’s favourite conditions! Findings Here Findings Here Hotspots and Gut Health As with most skin related problems, there is a huge link with poor gut health. We need to look closely at the Skin-Gut Axis. The skin and gut barrier share many qualities, as they’re both highly vascularised and innervated due to their role in both immune function, and neuro-endocrine function. When looking at the inside of the gut and the surface of the skin, to the naked eye they may seem worlds apart, but both are covered in epithelial cells which both make direct contact with the corresponding environment (the skin contacts particles in the air, things we touch etc, and the inside of the gut touches everything moving through the gut). The biggest similarity between the skin and the gut, is that they both possess their own microbiome. I’m sure you’ve heard us talking about the microbiome on many occasions; but that is because the microbiome is so incredibly important for health and proper functioning of various systems and organs. The microbiome is made up of all microbes the relevant organ uses, and makes contact with, including good (and bad!) bacteria, viruses, fungi, protozoa and other parasites. Gut Guardian There are many studies which prove positive links between probiotic supplementation and skin quality, which can be found in our blog about the gut-skin axis! Metabolites from the gut are shown to link directly to the skin’s ability to fight off ‘nasties’ which would in turn, reduce the risk of hotspots. An important neurotransmitter called Acetylcholine also plays a role in the functioning of the skin’s barrier, and how it deals with overgrowth of bacteria. Supporting the Body for Healing If your dog currently has a hotspot, it’s very important to treat it as soon as possible, as it won’t go away on it’s own. If the hotspot is oozing a yellow or creamy colour, you will need to seek veterinary attention, however it is important to work on the gut following use of antibiotics your vet may prescribe. Step 1: Shave the Fur Gently shave the fur around the hotspot – this enables you to see the full extent of the hotspot, and gives you a clean area to treat it, without the risk of fur getting into the wound. It also allows the hotspot to ‘breathe’, which is imperative in helping it dry up. Step 2: Clean the Area Using either boiled and cooled salt water, colloidal silver, Leucillin/Dew, or probiotic wound spray, gently clean the area to ensure there’s no bad bacteria on or around the hotspot. Pat it dry gently with a cotton pad. Step 3: Apply Green Clay With a clean, soft brush, such as a clean makeup brush, lightly dust some green clay on the hotspot – green clay is an excellent ‘staple’ for the dog cupboard (come on, everyone has a dog cupboard or drawer)! Green clay helps remove toxin from the skin, and helps dry the wound out. When purchasing your clay, ensure the product is 100% green clay, as some products contain added ingredients, including fragrances, which we definitely don’t want to use on our dogs! If you spot the hotspot getting wet through the clay, pop a little more on. Reapply the green clay once or twice per day, and keep the area dry at all times! Step 4: Prevent the Dog from Licking or Itching It’s important to not let the dog lick the wound, or get it wet. Itching the wound can aggravate it too, so don’t let them do this! You may need to resort to the cone of shame (Elizabethan collar, lampshade, or whatever you might call it!) for a few days to achieve this. Depending on where on the body the hotspot is, you may be able to use a clean t-shirt or sock to help cover it. Step 5: Wait! Hopefully
The Low Down on Pyoderma

Here at My Pet Nutritionist, we see a lot of worried puppy parents, struggling with pyoderma. Skin conditions are a very common topic at MPN HQ, so let’s take a dive into pyoderma, what it is, what causes it, and how to support the body with it. What is Pyoderma? The word pyoderma, literally translates to ‘pus in the skin’ (‘pyo’ = pus, ‘derma’ = skin). The condition presents as acne-like spots on the skin, often in the chin area, and around the lips. Pyoderma is a bacterial skin infection, the most common bacteria affecting it being Staphyloccocus intermedius. When there is too much of a specific bacteria present on the skin, the risk of pyoderma is significant. Pyoderma can happen at any age, but is particularly common in puppies – known as puppy pyoderma. Pyoderma can spread between humans and dogs, so it’s important to clean your hands thoroughly when you touch the affected areas on your dog. Findings Here Findings Here Causes of Pyoderma A common contributing factor of pyoderma is environment. Dogs living in warm, humid environments may be at a higher risk than those living in cool, dry environments. Humidity and warmth are essential for bacterial growth. Items in the environment can also contribute to the onset of pyoderma; the biggest culprit being dog bowls! Plastic bowls are particularly good bacterial breeding grounds because they scratch very easily (even if you cant see the scratches to the naked eye), which leaves crevices which are difficult to fully clean, allowing for bacterial growth. When the dog touches the bowl, the bacteria rubs onto the skin, causing pyoderma. An unhealthy gut is also a huge contributing factor to the overcolonisation of bacteria, which can cause pyoderma. 70-80% of the immune system lays in the gut. When the gut is damaged, through the use of chemicals, pest control pharmaceuticals, poor diet or ingredients, or any other cause of gut damage, this can have a severe effect on the body’s ability to get rid of the over-colonised bad bacteria. This leaves the dog more vulnerable to pyoderma. Secondary infection is also one of the major causes of pyoderma. It can be a secondary infection arising from a poor skin barrier, poor gut flora, intolerences to food, and contact allergies from the environment. As well as these common health complaints, there is also a genetic mutation called the Fillagrin mutation – this is much like eczema in humans. Findings Here Breed predisposition may also be a factor in the onset of pyoderma, however more research in this field is needed. Breeds thought to be at higher risk of pyoderma include: Spaniels (ususally lip fold pyoderma) Pekingese Pugs Boxers Bulldogs Shar Pei Read more about genes and skin health here! Finally, stress could contirbute to a dog getting pyoderma. Just like in us humans, stress-spots are very much possible. This is down to the skin having developed it’s own HPA axis. When the body is under stress, the adrenal glands release, and flood the body with stress hormones. This sudden burst of hormones can cause pyoderma to form on the skin. Read more about the skin’s HPA axis here! How to Prevent Pyoderma Prevention of pyoderma is something that may be overlooked by many pet owners, but it can happen to any dog at any age, so it’s something to be mindful of. Using the Right Bowls In order to reduce the risk of bacteria against the skin on the face, and around the mouth, we need to be mindful of the bowls being used for food and water. Glass (modern Pyrex is great, but avoid vintage Pyrex due to the potential for lead contamination!) bowls are a fantastic option, but beware if your dog is likely to pick it up and drop it. Stainless steel bowls are also a good option. Avoid plastic bowls, and be cautious using ceramic bowls, due to the ease of cracking of the glaze, which could then harbor bacteria. Keeping the Gut Healthy As previously mentioned, 70-80% of the immune system lays in the gut, so keeping the gut healthy is incredibly important. There are many avenues to keeping the gut healthy. Feed a fresh diet where possible – dry food is very drying on the gut, and often contains ingredients that can contribute to Leaky Gut. Fresh food, whether it’s raw or cooked using one of our recipes balanced to FEDIAF, is high in moisture, so is better for the gut. Avoid using worm and flea pharmaceuticals – these act a lot like paint stripper on the gut, and contain damaging ingredients, not to mention the risk of seizures, ataxia, and other nasty side effects. Don’t over-vaccinate! The adjuvants used in vaccinations can be detrimental to gut health due to the content of heavy metals. Use a probiotic, and if needed, a mucilage herb. Our product Gut Gurdian is a great choice, combining three mucilage herbs, calming chamomile, and some good quality soil based probiotics. Keeping the Skin Clean Keeping skin clean and dry is very important – focusing on the chin and mouth area, wrinkles/folds in certain breeds, and armpits and groin areas. You may wish to use a hypochlorous based product, of topical probiotic product to clean with, such as Leucillin or Dew (Hypochlorous based), or Provilan LUCAA+ probiotic products. Ensure areas are thoroughly dried. Keep On Top of Allergies Allergy symptoms usually include itching – constant itching of an area will irritate the skin, and leave it open to bacterial infections, especially in the hair follicles. It’s important to work on finding your dog’s triggers, and eliminating them. Keep the Environment Clean Try to keep the dog’s living environment clean! A clean environment, means less risk of bacteria. Less bacteria in the environment, reduces the risk of transmission to a host. How to Support the Body If your dog has pyoderma already, there are some things you can do to support the body through recovery. Let’s take a look at some
5 Reasons for Alopecia in Pets

The fancy way of saying hair loss, alopecia affects more pets than we may think. It may be congenital or acquired and for it to be managed effectively, we really need to understand it. So, let’s take a look at 5 reasons for alopecia in pets. What is Alopecia? Alopecia is the partial or complete lack of hairs in areas where they are normally present. We can imagine our pet’s hair (and skin for that matter) as a report card for the body. If it’s looking a little worrisome, we need to investigate. As we mentioned, alopecia can be both congenital and acquired. Congenital means the animal is born with the condition. Congenital hair loss may or may not be hereditary. It’s caused by a lack of normal development of hair follicles. It may be apparent at, or shortly after birth. Your pet may be born with a normal coat, and patchy or widespread hair loss occurs when they become a young adult. In acquired hair loss, your pet is born with a normal hair coat. It has or had normal hair follicles at one time and is or could produce structurally normal hairs. Subsequently, any disease that can affect hair follicles can cause hair loss. Certain diseases may destroy the hair follicle or shaft or interfere with the growth of hair. Some diseases can cause discomfort, leading to self-trauma (scratching and biting) and loss of hair. It’s important to remember that acquired hair loss can be inflammatory or non-inflammatory. What diseases can Interfere with the growth of hair? Diseases that can directly cause destruction or damage to the hair shaft or follicle include bacterial, fungal, or parasitic infections. It can also include inflammatory diseases of the skin along with skin trauma. These diseases tend to be inflammatory. Parasites and What You Really Need to Know But there can also be factors that inhibit or slow down follicle growth resulting in alopecia. Let’s take a look. Nutritional Deficiencies We are seeing more and more data around specific nutrients in hair growth and health. For example: – Low vitamin D status has been implicated in cases of alopecia, – Over-supplementation of Vitamin A is associated with alopecia – In a Biotin deficiency, signs include hair loss – Folate deficiency can result in hair, skin and nail changes – Vitamin C is known to aid iron absorption, the latter being implicated in hair loss – Hair loss is a common sign of zinc deficiency – Hair loss can be seen in Iodine deficiency as it’s a mineral that aids thyroid function (we’ll share why this is relevant next) We advocate a fresh food diet, rich in nutrients to support overall health. Check out our range of blogs on different nutrients if you would like to learn more. Hormonal imbalances So much of a factor, there is a condition deemed hormonal alopecia in dogs. This can be linked to neutering with many owners reporting hair loss or thinning post neutering. But when we say hormones, we are also considering thyroid hormones. The thyroid gland is active in the initiation of hair growth and replacement. Located in the neck near the trachea or windpipe, this gland produces hormones which regulate metabolism. Both hyperthyroidism and hypothyroidism can result in hair loss in the dog although hypothyroidism is likely the more commonly occurring form of hormonal alopecia in dogs. Initially hair loss is patchy, the coat is dry, the hair is brittle and easily pulled out. Quite often hyper pigmentation occurs. In some cases, secondary pyoderma and seborrheic dermatitis may follow. Ultimate Guide: Hypothyroidism Stress Hair loss can follow months after a traumatic event often making it difficult to connect the dots. Hair cycles through different phases and all follicles can be at different stages at any one time. What we now know is that high levels of stress can cause shifts in those cycles. This results in balding or thinning of hair. Stress also depletes nutritional resources along with impeding the digestion and absorption of them and as we’ve already mentioned, sufficient growth relies on a great supply of nutrients. Can Stress Affect My Dog’s Digestive System? Irritation When your dog scratches or bites because they are irritated, it can result in hair loss. Causes of irritation include: – Infection – Pain – Parasites – Sensitivities/allergies Itchy Dogs and Cats Naturally Things to Think About: Skin Health in Dogs Overgrooming Overgrooming can be a calming behaviour employed by your pet. This may be in response to stress or being overwhelmed. Its important to notice any change in grooming behaviour and establish the potential trigger. Stressors may include: – Change in routine – Addition of a new pet – Our own stress – Change in health – Time of year – holidays/fireworks/weather change If you think hair loss may be associated with stress, check out the following blogs for more information: The Pet Owner’s Stress Load Using Nutrition To Support The Stressed Dog Why Dogs Need To Chew 5 Nutrients to Support Your Anxious Dog Overgrooming can also be linked to pain and digestive issues, so check out our blog on licking behaviour for more information. Why Does My Dog Keep Licking Signs of Hair Loss Signs of hair loss may be obvious or subtle, depending on what’s causing it. Congenital or hereditary hair loss can be symmetric (appearing similar on both sides of the body) or located in one area only. It is not usually accompanied by inflammation. Signs of acquired hair loss are influenced by the underlying causes. Hair loss may affect an isolated spot or multiple areas; it may be symmetric or widespread. You may also notice inflammation, thickened skin, colour change, scaling, excessive shedding and/or itching. In addition, some causes may lead to the development of secondary skin diseases like infection or fluid discharge. Some questions to ask when establishing the cause of your pet’s alopecia? Are they getting the nutrients they need from the diet they are offered? Could stress
Does My Pet’s Skin Have Its Own HPA Axis?

Would you be surprised to know that the skin has developed its own local HPA axis to regulate its exposure to stressors? Recent mapping has found that all regulatory elements found in the central HPA axis are expressed in skin! Could this explain why skin issues tend to worsen when us humans are stressed? More importantly, when skin issues are the top issue facing the majority of dog owners we see here at My Pet Nutritionist, is this something we need to consider? The short answer is yes. So, let us take a deeper dive at what the HPA axis is and how this can influence our pet’s skin issues. The HPA Axis Most of us have heard at one time or another the mention of the HPA axis when we talk about the stress response. It stands for hypothalamic-pituitary-adrenal axis. In short, the hypothalamus in the brain receives a message that we are being exposed to a stressor, it then sends a message to the pituitary gland which then sends another message to the adrenal glands. It is the adrenal glands that release the hormones we typically associate with stress, like cortisol and adrenaline/noradrenaline. These stress hormones flood the body, and help it deal with whatever the stressor may be – and then when it has passed, the hormones stop being produced; the body then returns to homeostasis. This exact response also occurs in our pets when faced with a stressful situation, and so our pets too have a HPA axis. Now we know what the HPA axis does, let’s see how the skin has developed its own local axis. The Skin’s HPA Axis The skin is the largest organ of your dog’s body. It consists of three major layers: The Epidermis – (Epi – upon or above) this is the outer layer of skin, the protective layer. The Dermis – the dermis supports and nourishes the outer layer. It provides strength and elasticity. Here you will find collagen fibres, sweat glands, sebaceous glands, and hair follicles. You will also find cells that release histamine and other inflammatory mediators when faced with an allergy or injury. The Subcutis – (sub meaning under or below) this in the innermost layer of the skin, where you will find fat and muscles. Subcutaneous fat provides insulation, padding and storage for reserve energy. Not only does the structure of the skin prevent water and electrolyte loss to help maintain body homeostasis, but it forms a protective barrier which helps protect against infections, parasites, and the environment. This is the often-forgotten role of the skin – that it forms part of the immune system. When we think of the skin as the first layer of defence in the immune system, and therefore a type of radar, it makes absolute sense that it should have its own response to stress. It seems that skin cells, known as keratinocytes, can produce the same hormones and neurotransmitters that the “internal” stress response does. These include: corticotropin-releasing-hormone (CRH) cortisol adrenaline noradrenaline dopamine histamine acetylcholine All of these compounds help the body deal with a stressor, they include increasing heart rate, upregulating energy conversion and redirecting resources to those functions that are necessary. So, the skin, we can think of like a radar. It constantly senses the environment and reacts to various stressors like humidity, temperature, changes in the skin microbiome and of course injuries. CRH is possibly the most studied hormone and in the skin, it is involved in the proinflammatory response. When exposed to a stressor, CRH brings an inflammatory response to help manage the threat. If your dog scratched himself, the inflammatory response would be a normal part of healing. However, a natural by-product of this process is that it increases skin permeability which isn’t great long term. The skin serves as a protective barrier and if it becomes permeable, harmful compounds can sneak in, which can cause further problems around the body. Acute Vs. Chronic Stress Like everything, moderation is key – acute stress is manageable, the issue is when it becomes chronic. Where this becomes even more problematic is that animal studies have suggested that skin stress can initiate a central HPA axis response. When researchers exposed rodents to UVB radiation, they found increased stress responses in the adrenal glands. So, not only can the skin respond directly to a stressor, but it can bring the central response to the party too! What this means is that skin stress can cause body wide stress, and again this becomes an issue in chronic skin issues – leading to chronic activation of the “internal” stress response. To add insult to injury, psychological stress increases the production of “internal” stress hormones which then affects skin cell growth and function, compromising structure and altering skin permeability. So not only can skin stress cause psychological stress, but psychological stress can cause skin stress. You can see how this can become a challenging cycle to break. But what we must remember is that most functions in the body serve a necessary function and this mechanism (although challenging) is no different. HPA Axis and Skin Barrier The HPA axis in the skin responds to various stressors to regulate homeostasis – it serves to counteract any threat so normal function can resume. The compounds produced and released all serve important roles in maintaining a healthy skin barrier. ACTH (adrenocorticotropic hormone) is involved in melanin production which protects the skin from ultraviolet radiation. In dogs, it is melanin that contributes to skin and hair colour. In autoimmune conditions, melanocytes can be destroyed which results in depigmentation. This is also why if you have a dog who has repeated skin trauma (scratching etc) they develop visibly darker skin in those areas. Keratinocytes with more melanin display superior barrier function – which is why the body attempts to achieve it in repeated trauma. Endorphins are also released during skin stress. This enhances epidermal turnover rate, again to protect skin function. This could be why
Things To Think About: Skin Health in Dogs

Sadly, there are a colossal number of dogs that suffer with their skin, whether seasonal, or 365 days of the year. So, what on earth is going on? Let’s take a look at the skin in a little more detail, what it is, what its function is and what can go wrong. The skin is actually the largest organ of your dog’s body. It consists of three major layers: The Epidermis – this is the outer layer of skin, the protective layer. The Dermis – this layer supports and nourishes the outer layer. It provides strength and elasticity. Here you will find collagen fibres, sweat glands, sebaceous glands, and hair follicles. Here you will find cells and compounds involved in inflammatory response and therefore allergies. The Subcutis –this in the innermost layer of the skin, here you will find fat and muscles. Subcutaneous fat provides insulation, padding and storage for reserve energy. Not only does the structure of the skin prevent water and electrolyte loss to help maintain body homeostasis, but it forms a protective barrier which helps protect against infections, parasites, and the elements. In dogs, their hair also forms a barrier, therefore hair health is synonymous with skin health, and a dog’s coat type can actually influence skin status. Could My Dog’s Coat Type Contribute to Skin Issues? This protective barrier in fact forms part of the immune system. It is the first line of defence. It does this in two ways: – Through its physical structure – Through its microbiome Gut Guardian The Physical Structure As we have noted, the skin has three layers. Keratinocytes are produced in stem cells and they push their way up through the layers; being smothered in lipids as they go. When they reach the epidermis, they harden and form a tight structure. These eventually shed, and new cells make their way up. Issues arise when this tight structure becomes fragile. We can think of it in a similar thread to leaky gut. What Is The Gut Barrier? In cases of leaky gut, it becomes permeable to larger proteins or pathogens. In short, things from the gut get to places they shouldn’t really be. In leaky skin, the tight structure hasn’t formed, and so potentially harmful compounds can get through the skin layers and go to places they shouldn’t be either. When ours, or our dog’s immune system senses non-self-compounds (those that have gotten through its first line of defence), it mounts an inflammatory response resulting in swelling, itching, pain and so on. If we consider the itchy dog, they gnaw at their paws because they are itchy, this then compromises the skin structure causing further inflammation and so the cycle continues. The other way in which the skin serves to protect is through its microbiome. Not surprisingly when there is dysbiosis in the microbiome of the skin, conditions like atopic dermatitis often ensue. Dysbiosis simply means out of balance. There are good bugs, and bad bugs, and the aim is to keep them in balance. Tackling Atopic Dermatitis In Pets We know that in the canine, there are different species found on different areas of the skin. We also know that the populations found differ between allergic and healthy dogs and that lower diversity is often observed in recurring skin issues in the canine. So, what affects the diversity in the skin microbiome? Colonisation occurs during and immediately after birth. As the newborn puppy moves through the birth canal, he is exposed to a variety of bacteria from the Dam. Once puppy is born and grooming begins, Mum passes even more over to her offspring. What is important to note is that grooming behaviour is significantly reduced in the stressed Mother, and so less microbes are therefore shared with the offspring. This again demonstrates the need to fully research where you have your puppy from. In humans it is thought that the microbiome stabilises somewhat in the first 2-3 years of life, but there isn’t yet a clear answer on this time frame in the canine world. Given the development of a puppy compared to a human child, we can say for certain that those first few months of life are incredibly important. There is also a clear distinction between male and female microbiome, therefore suggesting hormonal influences. This poses food for thought in the neutered pet and how their microbiome is subsequently affected. The environment has a huge impact on the microbiome of the skin. There are noted variations in skin microbial communities between those living rurally and those in urban areas. There is also an increase in chemical use associated with urban living, which also influences the composition of the microbiome. Diversity is significantly reduced with the use of detergents and antibacterial cleaning products. Potentially pathogenic taxa is also increased as there are fewer good guys to keep the bad guys in check. This is why skin issues like acne or dermatitis are deemed western diseases; they simply just aren’t found on the skin of indigenous tribes or on that of individuals from non-industrialised societies. Findings Here Unnecessary use of antibiotics also affects the microbiome, along with excessive use of grooming products and of course nutrition. Does My Dog Have a Gut-Skin Axis? Skin Dysfunction When the physical barrier is broken, non-self-compounds can invade the body, kick-starting an inflammatory response. This results in redness, swelling and so on. These can be pathogens, but they can also be irritants. These irritants need to be managed by the body, but in some cases the burden can be too high and so the body remains in a state of chronic inflammation. This is why removing environmental exposure to toxins is so important in managing skin issues. Does My Pet Need To Detox? Skin issues often go hand in hand with food sensitivities, and so an elimination diet here is essential. Elimination Diets For Dogs But skin issues can also be a result of pain. Some dogs will nibble and chew at
Nutrients for Skin Health in Dogs

Skin issues are one of the most common issues we are faced with here at My Pet Nutritionist. The reasons are multifactorial and complex which is why we undertake a full assessment of pet health to establish what may be contributing to the issues. That said, we notice patterns, and so we’ve decided to share some of the nutrients we consider when supporting challenging skin issues. Vitamin D Despite its name, Vitamin D is actually a hormone that promotes calcium absorption. In human health, you will have heard it referred to as the sunshine vitamin as it is produced in the skin in response to sunlight (UV) exposure. In studies of hip fractures in humans, there appears to be a seasonal variation; more occur during winter months and fracture patients often have low vitamin D status. When supplemented with Vitamin D and calcium, incidences of fractures often reduce. Findings here So, vitamin D is particularly important in bone health, but we also appreciate its role in skin health. Vitamin D is a modulator of the sensing dendritic (Langerhans) cells and reduces inflammatory mediators. What’s super interesting is that Vitamin D levels are inversely associated with atopic dermatitis severity. What We Know About Atopic Dermatitis In addition, maternal vitamin D status is often linked to development of allergy. Vitamin D in Cats and Dogs Dogs are entirely dependent on dietary sources of Vitamin D as they are unable to synthesise it sufficiently through the skin. Food Sources of Vitamin D: Flesh of fatty fish (salmon,tuna and mackerel) Fish Liver Oils Beef Liver Egg Yolks Vitamin E Vitamin E includes several compounds, of which the most biologically active and widely distributed is alpha tocopherol. Vitamin E functions as an important antioxidant within cells, protecting lipids, particularly the polyunsaturated fatty acids in cell membranes against oxidative damage caused by free radicals and active forms of oxygen that may be generated during metabolic processes. The dietary requirement for vitamin E is influenced by the intake of selenium because of its role in glutathione peroxidase, with one nutrient partially able to spare a deficiency of the other. It is also influenced by the PUFA content of the diet and increasing this leads to an increase in vitamin E requirement. It has been recommended that the dietary ratio of alpha tocopherol:PUFA (mg/g) of 0.6:1 is maintained as a minimum to protect against PUFA peroxidation. Vitamin E therefore supports the health of skin tissues and protects it from damage. It accumulates in the mitochondria within skin cells and promotes collagen and fibroblast synthesis and decreases MMPs (compounds which can break down proteins like collagen). It also protects essential fatty acids from oxidation. Vitamin E is absorbed from the small intestine by non-saturable, passive diffusion into the intestinal lacteals and is transported via the lymphatics to general circulation. Sources of Vitamin E: Plant based oils Nuts Seeds Dark green veggies Pumpkin Red bell pepper Mango Rancid fats are particularly destructive of vitamin E, so these should be avoided in diet. Zinc The skin has the third highest abundance of zinc in the body. Its concentration is higher in the epidermis than the dermis. Zinc stabilises membrane structure which is key to skin health and is regularly used in a range of skin conditions including infections, inflammatory dermatoses, pigmentary disorders and neoplasias. What is particularly interesting is its role in allergic and inflammatory responses. Mast cells play an important part in adaptive immunity, they are found in the skin and many other places including the mucosal linings of the gut and lungs. Mast cells contain many granules which are rich in histamine, heparin and, you guessed it, zinc! Zinc is crucial to correct mast cell function and deficiencies are linked with the development of allergic disease. Findings here Zinc is crucial to effective wound-healing too – which is particularly important if through scratching your dog suffers trauma to their skin. MMPs are zinc dependent, and whilst their role does involve breaking down proteins, this is a necessary process to ensure skin health – like goldilocks, we want just enough turnover of cells in the skin for optimal health. Why Zinc is Important For Your Dog Essential Fatty Acids (EFAs) We’re likely preaching to the converted, but in ensuring skin health it’s essential to provide essential fatty acids for skin lubrication, sebum production and immune function. In atopic eczema there is evidence of a lack of conversion of LA to GLA, suggesting an abnormality in EFA metabolism. This may explain why some respond to GLA supplementation instead (GLA is found in hemp seeds/oil).
