Here at My Pet Nutritionist, acid reflux is one of the most common issues we come across in our consultations. Dogs with acid reflux may have it for a variety of reasons, from allergies to BOAS, and many other reasons in between. These dogs are often less tolerable of some generally preferred diets, so require a specific diet and supplement regime, which we will discuss here! A Bit About Acid Reflux Acid reflux is formally known as gastroesophageal reflux disease (GERD). When a dog eats, a mixture is formed in the stomach, comprising of stomach acid, salts and bile; this is called chime. Those with acid reflux suffer from the chime mixture entering the oesophagus. Acid reflux is a symptom of many underlying health conditions, and can be very uncomfortable. While acid reflux itself is not life threatening, it can lead to oesophageal ulcers due to repeated inflammation of the lining of the oesophagus, as well as the potential risk of aspiration pneumonia. Symptoms of Acid Reflux include: Bad breath Regular burping and regurgitation Tenderness of the stomach (bowing is the main sign of this) Constipation or diarrhoea Lack of appetite Lethargy Wheezing and dry coughs Weight loss Acid reflux is often caused by low stomach acid, contrary to what many may assume. Proton pump inhibitors are often prescribed under the assumption that the dog has too much stomach acid, however it’s often the exact opposite issue. This may seem an odd concept, however it becomes clear that when the stomach is lacking acid, it is unable to fully digest food at a high enough rate, so the food tends to sit in the stomach, which is then regurgitated. For more information on acid reflux, read our blog here! Diet When is comes to feeding a dog with acid reflux, it’s important not to feed processed foods. Processed foods such as kibble, are very inflammatory, which ultimately reduces stomach acid. A reduction in stomach acid can be a major trigger for acid reflux, as there’s less acid to digest foods. Fresh feeding for acid reflux dogs can be raw, or lightly cooked. Many dogs with acid reflux find it difficult to tolerate raw food, as the food sits in the stomach for a long time; when it sits in the stomach in chime, gasses are released, and the chance of reflux increases. Cooked food is often the best option. When feeding a cooked food, it is incredibly important to follow a balanced recipe, such as our recipes! Sticking to the leaner protein options such as the white fish recipe may be the best option, as feeding fattier proteins may cause more issue for dogs who are unable to digest efficiently. Acid reflux is often a symptom of allergies, so it’s important to get to the bottom of the dog’s allergies, and eliminate trigger proteins from the diet. To achieve this, an elimination diet should be carried out. Why not book in with one of our team for guidance through an elimination diet? Ensure there is plenty of fibre in the diet. Insoluble fibre increases gut and stomach motility, which is essential for those suffering from acid reflux. Some great sources of insoluble dietary fibre are: Broccoli Leafy greens Cauliflower Carrots Berries Findings Here Feeding a good variety of proteins (if allergy constraints allow), and a variety of plant matter can help ensure there are no vitamin deficiencies, which could contribute to acid reflux. In the human world, bariatric surgery patients often suffer with GERD, due to the inability to consume sufficient amounts of vitamins and minerals – nutritional deficiencies can impact our dogs too! Zinc deficiencies are common among acid reflux patients as it is thought that zinc helps protect the lining of the stomach. Findings Here Findings Here Working on getting to the bottom of any allergies and intolerances is important in helping relieve your dog of symptoms too! Allergies and intolerances are largely down to gut health, which causes a knock on effect on acid reflux. It’s also very important to choose the correct supplements to give your dog when suffering with acid reflux. Supplements The first, and most important supplement, or group of supplements we will be looking at, is those that aid gut health. Mucilage Herbs Mucilage herbs include Slippery Elm, Marshmallow Root, and Declycyrrhizinated Liquorice Root. These herbs are excellent for healing the gut, as they coat the digestive system. They not only help heal the gut, but they also soothe the oesophageal tract which is great for those suffering with acid reflux. Our probiotic and mucilage herb blend, Gut Guardian, may be perfect for your dog! Probiotics Probiotics are essential for a healthy gut. They help the gut microbiome flourish, which in turn aids digestion of foods, reducing the risk of chime sitting in the gut. Our aforementioned Gut Guardian supplement contains a great variety of clean probiotics, so may be a great choice for your dog! Findings Here Digestive Enzymes Some dogs, especially our acid reflux dogs, often suffer from poor digestion, due to insufficient amounts of the required digestive enzymes. When lacking such enzymes, food sits in the stomach in the chime mixture, which is them repeatedly regurgitated. Giving a good digestive enzyme may be pivotal to your dog’s recovery, or management of acid reflux. The two enzymes as play in this situation are Pepsin and Trypsin. Findings Here Rhodiola This is a herb, less commonly known in general, which contributes to responding to physical and mental stressors. As well as aiding those with diabetes, cancer, and anxiety, Rhodiola is great at helping the body cope with the physical stressors acid reflux brings. Findings Here Theanine Theanine is a non-protien amino acid which occurs naturally in tea. It plays a role in the prevention of acid refluc flare ups by increasing GABA activity, and reduce oesophageal sphincter relaxations. Together these reduce the symptoms of acid reflux. Findings Here If your dog has acid reflux, and you are unsure what to feed
Here at My Pet Nutritionist, we deal with a huge amount of dogs with a variety of allergy symptoms. Some of our clients dogs have been diagnosed with Mast Cell Activation Syndrome (MCAS), which is an incurable disease, presented as repeated anaphylactic symptoms. What are Mast Cells? Found in the epithelial and mucosal tissues throughout the body, Mast Cells help regulate the formation of new blood cells, eliminate bacteria and parasites, and vasodilation as well as bone growth, and mineral homeostasis. Mast Cells also regulate cell function in various cell types, including: Dendritic cells Macrophages T Cells B Cells Fibroblasts Eosinophils Endothelial Cells Epithelial Cells While they’re very important parts of the body’s tissues, Mast Cells do produce and release substances which can be harmful in large quantities, including: Histamine Leukotrienes Heparin Proteases Prostanoids Cytokines Chemokines Growth factors What Does Mast Cell Activation Syndrome look like? There are a variety of symptoms associated with MCAS, including: Swelling of the body, either localised to one area, or general swelling. Nausea and vomiting Acute diarrhoea Hives Reduced/low blood pressure Difficulty breathing Difficulty swallowing Inability to stand or walk properly (may seem ‘drunk’) If any of these symptoms shows, it is imperative to seek veterinary attention immediately. If these symptoms occur regularly, then your dog may need to undergo tests for Mast Cell Activation Syndrome. What Causes Mast Cell Activation Syndrome? It is unclear what causes MCAS to develop. It is often an idiopathic condition – meaning it happens without clinical reason. As it’s a condition related to allergies and intolerances, it’s important to discover, and eliminate these triggers from the diet, to reduce the risk reaction. One study suggests a possible link to the onset of MCAS, in patients with underlying immune disorders. Findings Here How Does the Vet Test for Mast Cell Activation Syndrome? Blood tests will be carried out on your pet, to check for any elevated levels of histamines (which are released in the presence of a foreign body), tryptase (the markers of degeneration of mast cells, often produced during anaphylaxis), and prostaglandins (fatty compounds with a hormone-like effect in animals, which regulated inflammation). If one, or all of these are present in abnormally elevated amounts, a diagnosis of MCAS may be given, particularly if these episodes are regular, and any prescribed antihistamines calm symptoms down. Findings Here The veterinarian may prescribe histamine 1 and 2 blockers, mast cell inhibitors, mast cell stabilisers, NSAIDs, immune suppressants, or other pharmaceuticals, which inhibit the production of histmaines and tyrosine. One note to remember; some pharmaceuticals block DAO (Diamine Oxidase), which is the enzyme which breaks histamine down. We need histamine removed from the body as soon as possible so this is something to discuss with your veterinarian. How Can we Support the Body? Diet At My Pet Nutritionist, we are all about feeding a fresh diet, whether it be raw, or lightly cooked. Your chosen diet MUST be low histamine. Avoid fermented foods like kefir, sauerkraut, and ACV as these are high histamine, and avoid high histamine plant matter such as spinach, pumpkin, strawberry, and avocado. If making bone broth for your dog, replace the ACV with lemon juice for a lower histamine option! Read more about Mast Cell conditions, and low histamine diets here! So, why is fresh food best for those diagnosed with MCAS? Fresh food doesn’t contain unnecessary bulking ingredients, such as rice, maize/corn, other grains, legumes or nightshades. These ingredients all cause gut damage and/or are biologically inappropriate, and can be a major histamine release trigger. Fresh food is minimally processed. Ultra processed ‘dog food’ is often contaminated with glyphosate, and Advanced Glycation End-Products (AGEs), which are both damaging to the gut. It’s much easier to work on allergies and intolerances, using fresh food. This is important as we need to keep intolerances under control. Keep the Gut Healthy As with all potential allergy related issues, we need to keep the gut healthy! The gut microbiome is incredibly important to keep immunity strong, and reduce the risk of foreign particles being detected in the blood stream, having leaked from a gut with poor integrity. Any leaked particles will be targeted by histamine responses, which will increase the risk of a MCAS flare up. Some gut health supplements include slippery elm, marshmallow root, Deglycyrrhizinated Liquorice Root. These should be paired with a good probiotic. The My Pet Nutritionist Gut Guardian supplement is perfect for dogs requiring gut work! Gut Guardian Work on allergies Ensuring any potential allergies or intolerances are under control is essential! Those suffering with any Mast Cell related conditions must have their histamine levels under control at all times, to reduce the risk of a flare up. As MCAS is heavily related to anaphylaxis, it is absolutely paramount that allergens are completely eradicated from the dog’s diet, and lifestyle. In order to eradicate the allergens, an elimination diet is to be carried out, whereby one single protein is fed for numerous weeks, and is eliminated from the diet if the dog continues to worsen. Once some safe proteins are established, it’s important to stick to feeding only these proteins. Read more on elimination diets here. Supplements As well as the aforementioned gut healing supplements, there are a number of other supplements which may help support the body. CBD: mast cells have cannabinoid receptors (like most cells in the mammalian body), which when inhibited, causes their production to be downregulated. Findings Here Findings Here Findings Here Quercetin: found in various fruits, green vegetables and stinging nettles, quercetin is a natural antihistamine as it downregulates the enzyme responsible for converting histidine to histamine. Quercetin also reduces production of prostaglandins and histamines as it inhibits the cells responsible for their release. The inflammatory cytokines which cause inflammation as a large part of MCAS, are also inhibited, which decreases their production. Findings Here Findings Here Findings Here Curcumin: this is the active component of turmeric; the main anti-inflammatory part. Another fantastic benefit of curcumin is that it inhibits
In Part 1, we discussed what Leaky Gut is, what autoimmunity is, and possible causes and symptoms of both. Read on to find out how they are linked, and more about the autoimmune diseases most commonly affected by Leaky Gut, as well as how we can support the body through diet, and supplements. How are Leaky Gut and Autoimmunity linked? A healthy gut microbiome is incredibly important as around 90% of the immune system is located in the gut! That’s quite a staggering figure, but it shows the importance of keeping the gut healthy and the microbiome strong. Let’s take a deeper look at some of the most common autoimmune diseases, and their link with Leaky Gut. Thyroid Issues One of the main issues with Leaky Gut and Autoimmunity, involves the thyroid. The body attacks the thyroid tissue as it recognises it as a foreign body. The reason the body sees thyroid tissue as a threat, is down to molecular mimicry. When the immune system releases antibodies to get rid of a threat, they bind at what is known as the ‘active site’, or ‘antigen binding site’. Antibodies are Y shaped proteins, and on the tips of the Y, the binding sites are found. These are a specific shape, to match the proteins on the antigens (the threatening particles). Take a look at the diagram at the top of this blog! Despite food particles clearly being very different to thyroid tissue cells, some of the attached proteins are the same shape on both the food particle and on the thyroid tissue cells. Gluten and Casein (dairy) are particularly alike to thyroid tissue cells, so when an antibody detects the protein it fits with, and binds to it, there’s a high chance it may be thyroid tissue instead of its real target; the food particle. Findings Here Findings Here Inflammatory Bowel Disease (IBD) A condition we hear a lot about, particularly on a professional basis as well as on social media posts when people ask advice on their poorly pets, is Inflammatory Bowel Disease. As per it’s name, this involves inflammation in the bowel, which can be as a result of Leaky Gut. When looking at IBD, diet is so important – many processed foods contain emulsifiers, which can include Cellulose Gum, and Polysorbate-80 (though this one is most inhuman foods, not pet foods). These have been found to interrupt interactions between the bacteria in the intestine, and the gut wall; resulting in the gut wall being less protected than it would be without the presence of these substances. This lack of positive interaction, teamed with the already permeable gut wall (due to Leaky Gut) can cause the onset of IBD. Findings Here Small Intestine Bacterial Overgrowth (SIBO), Yeast, and Candida can also contribute to IBD (and are all symptoms of Leaky Gut), which causes inflammation of the bowel, which further increases the risk of IBD onset. Studies show a huge affect on gut permeability when up-regulation of the protein called Zonulin is present. Zonulin helps regulate the permeability of the small intestine, but is detrimental in high numbers as it causes the gut to become more permeable. It is secreted by numerous organs within the body, and can be linked to Leaky Gut and the onset of IBD. Findings Here Findings Here Findings Here Immune-Mediated Haemolytic Anaemia (IMHA) IMHA is one of the more worrying autoimmune diseases, with a mortality rate close to 70%. There are many reasons a dog may be diagnosed with IMHA, including Vaccine Induced IMHA. When a dog has IMHA, the body is attacking it’s own red blood cells, which are important for transportation of oxygen from the lungs to all parts of the body for healthy muscle usage. IMHA can be caused in some rare cases, by a deficiency in Vitamin B12, which can be linked back to Leaky Gut. IMHA is also often as a knock on effect of other autoimmune diseases like Systemic Lupus Erythematosus. Findings Here Findings Here Diabetes Largely linked to Leaky Gut, Diabetes mellitus often requires lifelong medication. Similarly to the mimicry of thyroid tissues by antigens like Gluten and Casein, the onset of diabetes can be facilitated through normal cells being attacked incorrectly by the antibodies circulating the bloodstream. With diabetes cases, the immune reactions affect, and damage pancreatic beta cells (responsible for producing and secreting insulin), which then causes the over-production of cytokines, which in turn causes insulin resistance within the body. Healing the gut, and decreasing gut permeability may help relieve sufferers of diabetes symptoms. Studies show Type 1 Diabetes can be caused as a result of gut damage, but can also cause gut damage. Findings Here Findings Here Findings Here Findings Here Immune-Mediated Trombocytopenia (ITP) ITP is a platelet disorder, in which sufferers are unable to properly clot blood due to low platelet counts. Pathogenesis of ITP as a result of leaky gut has been proven to be due to imbalances in the gut microbiota, and the presence of cytokines which interfere with metabolism of fats. Patients with Leaky Gut, as we know, have a very imbalanced microbiome as bacteria leaks out through the channels in the gut wall. Certain strains of bacteria play an essential role at keeping ITP at bay, but are found to be of low levels in those diagnosed with ITP. When these helpful bacteria are leaked from the gut, cytokine production is increased, which then affects the metabolism of fats, which in turn causes pathogenesis of ITP because the lack of fat metabolism causes a lack of available fatty acids to enable the blood to clot. Findings Here Findings Here Findings Here Rheumatoid Arthritis The previously mentioned protein called Zonulin plays a part in Rheumatoid Arthritis (RA); a joint related autoimmune condition. Just like in IBD, when Zonulin is over-represented, the gut permeability cannot be controlled, and allows useful and harmful substances to enter the blood stream, which are then detected as threats by the immune system. The upregulation of
At My Pet Nutritionist, we regularly help people with their pets suffering with Leaky Gut Syndrome. There is a lot of evidence to link Leaky Gut with a variety of autoimmune diseases; issues we so very often offer support for. Read on to learn more about Leaky Gut, and the role it plays in autoimmunity. What is Leaky Gut? The condition is growing more and more common in both us humans, and our canine counterparts, and can lead to some pretty serious health issues, long term. The name ‘Leaky Gut’ does somewhat give the game away, but let’s look deeper into what actually happens in the gut of a normal dog,compared to one with Leaky Gut. In healthy individuals, after eating, the food passes through the gut. The gut consists of the stomach followed by the small intestine, followed by the large intestine (known as the ‘colon’), through which nutrients from the digested food are absorbed, before the waste is pushed out through the rectum, then anus. To enable a large surface area, for optimum nutrient absorption, the small intestine is lined with small finger-like structures called villi, which themselves are covered in even smaller finger-like structures, known as microvilli. The gut also houses lots of good bacteria to aid digestion – the colonies of good bacteria, along with yeast cells, any viral particles, or parasitic burdens, are collectively known as the ‘microbiome’. The gut wall is extremely thin, to allow efficient nutrient absorption. The cells lining the gut stay close together, and are supported by the interactions of immune cells, and good bacteria in the gut. In those suffering with Leaky Gut, inflammation occurs in the gut for various reasons, which causes the tight intestine wall to permeate, creating microscopic channels between the cells. Proteins/partially undigested foods then leak out through these channels and are detected by the immune system as a threat, causing a histamine response to occur, which is why one of the most common symptoms of Leaky Gut, is food intolerances. Other symptoms of Leaky Gut include: – Autoimmune Diseases – Issues with stools or sickness – Joint issues – Yeast – Problems concerning other major organs in the body – Hypothyroidism – Changes in behaviour; often anxious behaviour and short tempered behaviour Possible Causes of Leaky Gut include: – Over-use of vaccines; the adjuvants damage the gut flora – Use of certain pharmaceuticals ^ Flea, tick, and worm medications; they disrupt the gut microbiome by not only eradicating the visiting parasites (or often lack thereof), but the good bacteria too. ^ Antibiotics; these wipe out the good and bad bacteria ^ Antihistamines; these can interfere with the production of mucus in the gut, and can also interfere with the proper functioning of Diamine Oxidase (DAO), which is the enzyme responsible for breaking down, and removing histamine from within the gut. ^ NSAIDs and Steroids; these can cause ulcerations in the gut and interfere with mucosal production. – SIBO and Yeast overgrowth; Small Intestine Bacterial Overgrowth and Yeast damage the gut lining – Diet; feeding a dry food diet can put stress on the gut. Kibble often contains Glyphosate, which is an antibiotic herbicide and is toxic, as well as very damaging to the gut. Diets inclusive of legumes and other high-lectin content pulses, nightshades and vegetables may contribute to Leaky Gut as lectin causes poor gut integrity. Microscopic moulds often found on kibbles, known as mycotoxins are also detrimental to gut health, contributing to Leaky Gut. – Stress can have a huge effect on the gut integrity, as stress leads to inflammation – Ageing; as our dogs age, the microbiome becomes less diverse which leads to gut damage. Findings Here Findings Here Findings Here Findings Here Read our full Gut Dysbiosis blog here What is Autoimmunity? To better understand the link between Leaky Gut and Autoimmunity, we need to understand more about autoimmunity, what it is, and how it affects our pets (and us too!). Autoimmunity is sadly fairly common in both humans and pets and is often overlooked. When an individual has an autoimmune disease, the immune system releases antibodies and T-Killer Cells (cells of the immune system which target and kill cells infected with viruses and cancers) even when they are not in the presence of a necessary target, which causes them to attack normal, previously healthy parts of the body. In layman’s terms, the body attacks itself! There are more than 80 different autoimmune diseases in existence, though not all of these affect dogs. Some of the most common autoimmune diseases we see in dogs are: – Hypothyroidism – Inflammatory Bowel Disease (IBD) – Immune-Mediated Haemolytic Anaemia (IMHA) – Diabetes – Immune-Mediated Trombocytopenia (ITP) – Rheumatoid Arthritis – Hypoadrenocorticism (Addison’s Disease) – Periodontal Disease – Degenerative Myelopathy – Immune-Mediated Polyarthritis (IMPA) – Systemic Lupus Erythematosus (SLE) – Discoid Lupus Erythematosus (DLE) Symptoms of Autoimmunity These will, of course, vary depending on which autoimmune disease an individual has, but general signs and symptoms of autoimmunity, which may spark a look into further investigation with your veterinarian, include: – Constant lethargy – Racing, or very slow heartbeat – Weight loss (often dramatic) – Increased panting – Collapse – Excessive drinking and urination – Seizure activity – Discolouration of gums and skin – occasionally yellowish as a result of jaundice. – Hair loss or coat texture changes – Regular vomiting and diarrhoea – Increased temperature – Behavioural changes, including aggression or depression Findings Here Read Part 2 here to find out more on the autoimmune diseases affected by Leaky Gut, and how we can support the body, naturally. If you feel your dog may be experiencing Leaky Gut, or an autoimmune disease, seek veterinary attention, and book in for a consultation with one of our team! Team MPN x
A common issue presented among our clients, readers, and followers here at My Pet Nutritionist is low stomach acid (hypochlorhydria).There are numerous signs and symptoms that your pet may have low stomach acid; let’s discuss the most common ones! Acid Reflux Low stomach acid will usually result in Acid Reflux, or it’s most severe form, Gastroesophageal Reflux Disease (GERD). When a dog has GERD, there is a backflow of stomach acid. Dogs presenting with the below clinical signs, are often prescribed Proton Pump Inhibiting drugs (PPI’s), which suppress acid secretion in the stomach, and can provide temporary relief, but can cause more implications in the longer term, and will not erase the cause of the low stomach acid, or its symptoms. Most commonly seen in brachycephalic dogs and cats, and those with shorter a oesophagus, low stomach acid is being seen more and more often in the animal health and nutrition industry. Read our Guide to Acid Reflux here Regurgitation Probably the most common sign of low stomach acid is regurgitation (bringing up partly digested food), bringing up bile (clear, yellow substance produced in the liver, and stored in the gallbladder for use during digestion), and sometimes bloody vomit. These various nauseating problems occur due to the mixture of digesting/partly undigested food, known as chyme, sitting in the stomach for prolonged periods of time. When it sits in the stomach for so long, inflammation worsens in the area, which ultimately causes food or bile to come back up, since it is unable to go down! A popular supplement used as part of many dogs’ battles against regurgitation, is Deglycyrrhizinated Liquorice (DGL)which is a great anti-inflammatory for the stomach, and helps heal the gut. Findings Here Indigestion Dogs and cats fed a raw diet while suffering from low stomach acid, will often be unable to properly digest meat and bone. Pets with indigestion will often have pieces of bone and fresh-looking meat in their vomit. In order to digest bone and meat (or other sources of protein), the gastrointestinal juices must be acidic. If there is little acid available, the pet will be unable to digest and utilise the bone and meat. During fasting (between meals), the dogs gastrointestinal juices are around pH 7.3, which is almost neutral. In anticipation of food, during eating, and during the process of digestion, the gastric juices drop to a very acidic pH of 1 to 2 – that’s not too dissimilar to the pH level of battery acid! Findings Here We often recommend a gently cooked diet as per our balanced recipes for those suffering with low stomach acid, as cooked meat and bone substitutes are much easier to digest. Lip/Air Licking Another very common sign of low stomach acid is lip licking, often called ‘lip smacking’, as well as licking the air. These are not only signs of pain, but also signs of nausea in both dogs and cats. Drooling and lack of appetite are also signs of nausea in both species. Stomach Pain, Bloating and Gas Due to the inability to digest food properly and efficiently, stomach pain (particularly after eating) is common in those suffering with low stomach acid production. Dogs especially, often display unusual behaviours like bowing (just like the ‘downward dog’ yoga position!) when their stomach is sore. This position can help relieve the pain. Some pets will look sharply at their stomach when in pain, which is a very subtle sign, so often one missed. Cats will often become more vocal when in pain, or lose their appetite. Stomach pain can also be caused by bloating, and excessive gas. The inflammation of the stomach can lead to visible bloating. The gasses produced by the chyme mixture in the stomach will also further add to the bloating. In order to release these gasses, owners of pets suffering with low stomach acid will often notice more passing of wind through the anal passage, or through burping. Probiotics and gut healing protocols can help reduce these symptoms. Another cause of bloat and excessive gas is bacterial overgrowth in the gut. Known as SIBO (Small Intestine Bacterial Overgrowth), the overgrowth of bacteria alters not only gut motility, but also affects the gut-brain axis. Findings Here Findings Here Burping/Empty Swallowing Burping and empty swallowing (regular swallowing despite the pet not eating or drinking beforehand) are signs the pet has low stomach acid. Due to the low stomach acid content, the chyme will produce gasses which will cause burping and the feeling of sickness, hence the swallowing. Dogs and cats may also swallow when they have regurgitated, which would appear as empty swallowing. Constipation and Diarrhoea Irregular bowel movements and consistency of bowel movements can be a sign of low stomach acid in dogs and cats. Due to the lack of appropriate levels of stomach acid in these individuals, their metabolic rate decreases, meaning that important parts of the diet will take differing times of absorption, which can play havoc on the bowel. Pets who struggle with indigestion of raw bone may struggle with diarrhoea. A large part of the problem when it comes to irregular bowel issues, is down to bacterial overgrowth in the gut. As previously mentioned, SIBO has a huge impact on the gut-brain axis, as well as gut motility, leading to malabsorption of nutrients which can ultimately lead to both chronic and non-chronic diarrhoea and constipation. Conditions such as IBD may be diagnosed following SIBO in dogs with low stomach acid. Findings Here Bad breath As the chyme is stuck in the digestive system for such along time, it can lead to bad breath. Many pet owners associate bad breath with oral hygiene/dental issues, which is absolutely a possibility. These owners are often startled to see their pets have perfect oral health; yet are still suffering from bad breath. Digestive issues are a very common cause of bad breath, so it’s important to look into these too, especially SIBO. Focusing on the gut health should dramatically improve bad breath.
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
Whether you are purchasing for your own pet, or for a friend or family member, buying pet products, just like food, can be a bit of a minefield. When more and more of us are trying to live sustainably, can we do this with our pets too? We’ve popped together some things to consider before you buy that next toy, chew, grooming product or bed! The Problem with Plastic It’s clear that the majority of pet products on the market are unfortunately made from plastic. Not only have we got the global issue of too much single use plastic, but it is actually harmful to health (yes, that includes our canine companions too)! A common chemical used in the production of plastic is bisphenol A, also known as BPA. We’re sure you’ve heard of it. Studies have shown that BPA affects the reproductive systems of laboratory animals suggesting it disrupts hormones, and many more body functions. Not only that but you will often find phthalates in plastic toys too. These are what makes the toy more flexible and durable. These too are known as endocrine disruptors. We know that plastic doesn’t break down (you only have to look at the poop of a post-toy-assassination) so when your dog has gotten bored of that particular toy, you’ll dispose of it, but it can’t be recycled, so it will just end up in landfill for hundreds of years! If you are looking to raise a plastic free pooch, it’s not as hard as you think. Opt for toys made out of natural materials like cotton, rope, canvas, wood, wool or bamboo. You can even make your own out of old T-shirts or towels (reusing and recycling is much better for the environment). The other thing to check when you purchase, is how durable the product is. You want to make sure it is safe; that it doesn’t have small parts that can be chewed and swallowed. Squeak toys are the worst! Dogs instinctively want to get to the squeaker, but it’s easily swallowed and can cause an obstruction. You want an item to last, so if your dog is a toy-assassin, then it’s just a waste of money buying one you know will be killed in a matter of seconds! Whilst toys are often gifts of choice, chews and treats are firm contenders too! But this can be even more of a minefield for dog owners! It pays to look at the labels of chews or treats. You need to recognise the ingredients listed. Ideally, the first ingredient should be a meat protein. View chews and treats like you would when searching for a new dog food. Whilst it’s a complementary addition to their diet, it still needs to be beneficial to their health! Look at where it is made and source as local as possible. If you are raising a plastic free pet, then opt for packaging that is totally recyclable or biodegradable too. If you choose natural chews, they often don’t even need packaging! If you are considering buying grooming products for your pet or family member pets, again reduce plastic where possible. Shampoo bars are becoming increasingly popular. They are often cruelty free and do not contain parabens, phthalates or sulfates. Most shampoo bars come in paper packaging which is 100% recyclable. Choose brushes with natural bristles and wooden handles. Perhaps bedding or blankets are your next purchases? Choose items that are machine washable, so you can keep them for a longer period of time as opposed to disposing of them when they get too dirty! When you are washing them, pop them in a guppybag. This acts as a microfilter, stopping tiny plastic particles from getting into the water system. This is especially important for fleecy items as they are made from plastic (albeit recycled). Whilst you may be trying your best to buy safely and sustainably, it can become an issue when friends or family buy for your pet. Many of us have accepted gifts knowing they will just end up in the bin. This is sad for a number of reasons. The sale has already taken place, so there has been indication of demand and secondly, it’s another item in landfill. Consider setting up a wish list for your pooch, with safe and sustainable items on. Or, start buying these products for friends and family and explain why you are so excited about them. Hopefully, they’ll too see the benefits and pass them on the next time they buy a gift. As Bernadette Jiwa suggested “…in a world where it’s easy to be cheaper and faster than the competition, we now recognise the limitations…humans are wired to do what feels good and what feels good to customers right now is to use their choices and purchasing power to support the building of a better tomorrow.” Thanks for reading, MPN Team
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
Time and time again we see that our pets are contaminated with a range of chemicals and toxins, but recent data indicates that they boast even higher levels of contamination than us humans. Let’s take a look at the data and see how we can reduce contamination. How Contaminated Are Our Pets? In a recent study, dogs and cats were contaminated with 48 of 70 industrial chemicals tested, including 43 chemicals at levels higher than those typically found in people. The chemicals included: plastics and food packaging chemicals heavy metals fire retardants stain-proofing chemicals Average levels of many chemicals were substantially higher in pets than people, with 2.4 times higher levels of stain- and grease-proof coatings (perfluorochemicals) in dogs, 23 times more fire retardants (PBDEs) in cats, and more than 5 times the amounts of mercury. Dog Contamination Blood and urine samples have shown contamination with a range of chemicals, including 11 carcinogens, 31 chemicals toxic to the reproductive system, and 24 neurotoxins. Cat Contamination Cat samples contained 46 chemicals altogether, including 9 carcinogens, 40 chemicals toxic to the reproductive system, 34 neurotoxins, and 15 chemicals toxic to the endocrine system. Endocrine system toxins raise particular concerns for cats, since they include the thyroid toxins and fire retardants, PBDEs. Thyroid disease (hyperthyroidism) is a leading cause of illness in older cats and it is regularly linked to fire retardant exposure. Hyperthyroidism in Cats Let’s look into individual exposure in a little more detail and some evidence backed links to certain health issues. Potential Exposures: – A dog eating scraps from the floor may swallow dirt and dust tracked in from the outdoors and contaminated with heavy metals and pesticides. – Dogs and cats often eat food processing and packaging chemicals that contaminate their food, day after day and year after year, resulting in cumulative exposures. – Chew toys might contain plastic softeners. – Foam beds might be infused or coated with fire retardants and stain-proofing chemicals. – Plastic water bowls might leach hormone disruptors. Evidenced Links to Health Issues: – “Teflon toxicosis” has been the cause of death for hundreds of pet birds nationwide whose lungs filled with blood after they breathed in toxic fumes from overheated, non-stick pans – what may this be doing to our pets? – Studies show bladder cancer at a higher rate in dogs living near industrial areas or if their owners use lawn and garden weed killers and insecticides. – In addition, in a case-control study of bladder cancer in household dogs, the cancer risk was significantly increased by the use of topical insecticides. For 1-2 topical applications per year, bladder cancer risk was increased by 1.6 times, whilst more than 2 applications per year the risk was 3.5 times greater. – Lead toxicosis has been found in dogs and cats in homes with chipping lead-based house paint. – Malignant lymphomas are found in dogs whose owners use certain lawn pesticides. – Mouth cancer (oral squamous cell carcinoma) has been found in cats exposed to certain flea repellents. We must also consider the foods that we are feeding our pets. A massive recall was initiated in March 2007 after many pets became sick or died after eating certain brands of pet foods. Poisonings of pets were traced to the presence of melamine and cyanuric acid in imported wheat gluten that was used for pet food production. Findings Here According to the Environmental Working Group: “These events highlight the vulnerability of pets and their owners who, due to insufficient government oversight over chemicals present in pet food, are left to trust that the pet food industry will regulate itself.” The list of potential contaminants is endless, which can leave us a little disheartened as pet owners. But, information is power, and if we know what could be compromising our pet’s health, we can take steps to mitigate the damage. We can limit exposure to contaminants as much as possible by opting for a low-tox lifestyle. What does a low-tox lifestyle look like? Plates instead of plastic bowls Non-toxic grooming products Steam mops White vinegar and baking soda for cleaning Wooden floors or tiles with washable rugs instead of carpets Natural flea and worm options Fresh food diet Filtered water Natural garden care and insect repellents Air purifiers – machines or bamboo charcoal bags Safe plants (for both cats and dogs) The thing to remember is that many of us have become accustomed to sweet smelling homes, but all we really need is a clean home. Wash rugs, blankets and beds frequently (in white vinegar to keep wet dog smells at bay) and if you have guests coming over, pop a vase of (safe) flowers on the table. We regularly see how a high-tox lifestyle has compromised pet skin health, along with their gut and liver function. And as we can see from the evidence, contaminants are implicated in many more health issues in our pets.

Whether it’s a trail of slobber across your face or you’re sitting in wonder at your dog licking the slate around the fireplace, dogs like to lick. Everything. We find it endearing and a sign of affection when we get a tongue to the ear, or we just assume they’re practicing good hygiene when they are licking their paws. More often than not, only your dog knows why they are licking that rock in the garden. But there are occasions when there is more to licking behaviour. Let’s delve into the world of allergies, stress, pain and just good old-fashioned grooming. Why do dogs lick their paws? If you made a tally of a day in the life of your dog, licking paws would come in pretty high. More often than not, dogs will lick their paws to groom themselves. So, if they’ve come in from their walk or even just from a mooch around the garden, you’ll find them preening themselves and even having a little nibble. This is generally expected behaviour. However, this can become excessive if your dog is irritated by something they walk through or on. Grasses, pollens and toxic chemicals can all cause irritation to their sensitive paws. You also run the risk of salt or antifreeze exposure during extreme weather. Not only does this irritate them externally, but through grooming, they ingest it and can cause subsequent damage internally. It’s always best to rinse your dog’s paws when returning from a walk and give them a towel dry. In extreme climates you can even apply an all-natural paw balm or simply some coconut oil. Dogs will also lick parts of their body that are painful or stiff; so, if your dog has strained or sprained their leg, they may start licking their paw of the affected leg. Long nails can cause pain too, so check your dog thoroughly if the licking is a new behaviour. Dogs In Pain Excessive licking is usually identified by a reddening of the hair on the area being licked, so it’s pretty easy to notice. This is thanks to a protein found in the saliva which stains the hair. It’s not blood, don’t worry. However, excessive licking can cause trauma to the hair and skin, leaving inflamed, red and sore patches. This is why the underlying issue needs to be tackled as soon as possible. Why do dogs lick people? Some dogs lick people, some dogs don’t. How they have been raised plays a huge part in this. Quite often, if a dog has been allowed to lick their owner, they may lick other humans. If, however, an owner doesn’t want this behaviour, then they will ignore it. The dog won’t get a response and often will cease to do it. Those of us crazy dog owners who couldn’t care less whose canine slobber we get covered in, usually become jovial, we smile or laugh. The dog, even in the absence of a “food” reward, is receiving positive reinforcement. Dogs can read human emotion and, maybe, if they think we like being licked, they figure it’s just something they should keep doing. Why do dogs lick faces? It’s impossible to know for certain why dogs like our faces, but we think it comes from their puppyhood. If you notice how Mum Dogs behave with their puppies, they spend a huge time licking them, grooming them. The great thing is, the more a Mum Dog does this, the more resilient her puppy is as they grow. They are also less reactive to stress. It is believed that this behaviour reduces the amount of stress hormones in the puppy’s body. So, we could argue that our dog licks our face because they are imitating the behaviour they experienced. We could also argue that our dogs do it to help soothe us (do they do it more if we are stressed?) The less endearing explanation is that actually, as a dog’s sense of smell is so great, they’ve sniffed out a crumb or remnant of food/drink around our mouths and actually just want a taste. Why do dogs lick your feet? Most will agree, feet are the smelliest part of the human body. In terms of biology, this is pretty accurate. Human feet have more sweat glands per inch than anywhere else on the body. Wearing tight fitting socks and shoes also keeps moisture and heat in, providing a great environment for bacteria to multiply. Dogs have a great sense of smell, so when there could potentially be a great mixture of water, ammonia, potassium, nicotinic acid, magnesium, chloride, sodium, creatinine, uric acid, ascorbic acid, thiamine and riboflavin (also known as sweat) and then a whole host of different bacteria, why wouldn’t your dog have a lick and see what they could find? Dog’s explore their world through smell and sight. Maybe they’re just drawn to the smelliest part of the human body? (we’re not saying you have smelly feet, they can just find more information there). Why do dogs lick the air? Whilst dogs do explore their world through smell, and smell contributes massively to taste experience, it’s unlikely that when your dog is licking the air, they are trying to “taste” the air. They are more likely, stressed. Licking is a stress behaviour for canines. Notice when your dog is licking the air; what is happening in their environment. Is someone touching them? Has someone new come into the home? Are you near their food? Is someone near their toy? Are kids nearby? Have you made a fuss and touched a certain part of their body? This could indicate pain. It’s important to notice the trigger and also watch for other stress behaviours like; drooling, panting, yawning, pacing, head flicking or turning away from the stressor/trigger. Find the trigger and remove it. Licking is a warning signal; ignorance often leads to escalation. Why do dogs lick their nose? Like we mentioned above, this is most likely a sign of
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
If you have followed us here at My Pet Nutritionist for any length of time, you’ll know that we’re great advocates for the inclusion of veggies for their prebiotic and fibrous benefits. But there are also times where we would avoid certain veggies. Keen to learn more? Read on. Nightshade Vegetables and Arthritis Some believe that the solanine contained in nightshade vegetables like bell peppers, tomatoes and potatoes may increase levels of inflammation in the body. Whilst there is disagreement over the mechanism, humans suffering with arthritis often report a worsening of symptoms after eating nightshade vegetables. There is one school of thought that it could be more to do with a sensitivity to the food, which results in an inflammatory response, contributing body wide circulating cytokines. Whilst nightshade veggies are a great source of certain nutrients, there are other foods which can provide these and so if you notice a worsening of arthritic symptoms, it’s an easy change to make. Natural Arthritis Guide Lectins and Should My Dog Eat Them? Goitrogenic/Cruciferous Veggies in Thyroid Issues The thyroid gland produces three important metabolic hormones, thyroxine, triiodothyronine, and calcitonin. Thyroid stimulating hormone (TSH) produced by the anterior pituitary gland controls the production of these hormones. Iodine, derived mainly from sea-foods or consumed in the form of iodised salt, is utilised for producing T3 and T4 hormones. T3 and T4 hormones affect every cell and organ in the body. They regulate the rate at which the body uses energy, which subsequently affects weight loss or gain. They raise or lower body temperature. These hormones influence the speed at which food moves through the digestive system. They affect brain development and also control the way muscles contract. Common thyroid disorders in our pets include hypothyroidism and hyperthyroidism, meaning the thyroid is either under-active or overactive. Ultimate Guide: Hyperthyroidism Ultimate Guide: Hypothyroidism Goitrogens are plant chemicals that can decrease the production or activation of thyroid hormone, meaning they slow thyroid function. These foods are commonly known as goitrogenic, which means they contain substances which slow the thyroid’s ability to uptake iodine. If eaten in excess, these foods interfere with the efficient function of the thyroid gland. The strongest goitrogens are soy products, but moderate inhibitors include: Broccoli Cabbage Kale Cauliflower Brussels sprouts All/Starchy Veggies in Yeast Issues Around 150 strains of yeast are thought to utilise starch as a sole carbon source for aerobic growth. In short what this means is starch is food for yeast! Starch, or amylum, is a complex carbohydrate that exists in many foods, including grains, vegetables, and fruits. Sources of starch are primarily: Maize Tapioca Wheat Potatoes The extraction of pure starch from food produces a white, tasteless, and odourless powder that doesn’t dissolve in cold water or alcohol. Starch is a natural polymer, or polysaccharide, meaning that it is a long chain comprising one type of molecule. Starch consists of glucose molecules. It can occur in two forms: amylose and amylopectin. You may be familiar with this wording as amylase is a digestive enzyme which helps break down starch. Yeast or candida is an opportunistic fungal pathogen but a normal part of the gastrointestinal flora and genital tracts. The issue is when there’s an overgrowth. If we are tackling an overgrowth, the last thing we want to do it continue feeding it and as you’ve now realised, starch is a great food source for yeast! Is Your Dog A Yeasty Beasty? All Veggies in the Case of An Elimination Diet When we are supporting a dog with digestive issues, we need to know exactly what is contributing to their symptoms. For this reason, we would avoid feeding all vegetables when running an elimination diet. Just like a dog can have a sensitivity to a certain meat type like chicken or beef, they can also have a sensitivity to fruits and vegetables. It’s important to remember that an elimination diet is a diagnostic tool – not a long-term lifestyle and in some cases, a means to give the immune system a welcomed break. In running an elimination diet, we follow the 4 R’s. – Remove – remove offending foods, one at a time and note changes in symptoms. Quite often, even offending foods can be reintroduced at a later stage. – Repair – support immunity and gut healing with 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. – Restore – 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 is often best left whilst we get to the root cause. – 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 supply will help get the digestive system back to doing what it does best! Elimination Diets For Dogs We can’t deny the fibrous benefits of many vegetables along with their nutrient content, but when we are tackling a specific health issue in a pet, we must prioritise. We can often get those benefits in other ways if we think outside of the box.
