If you’re reading this blog post, it’s quite likely that you have just become, or will soon become a puppy parent, owner, guardian, or whatever you prefer to go by! Getting a puppy can be both exciting and scary – the dog world is such a minefield when it comes to information on general health and wellbeing. To set our pups up for a life of health, we need to be super careful what we feed them! Here at My Pet Nutritionist, we bring you this blog post, where you will find out what is best to feed your new, or future addition! Dietary Requirements for Puppies Puppies require different nutrients for different functions; providing too much, or too little of some nutrients can have a detrimental effect on health, so let’s take a look at nutrients, what theyre for, and the risks of a deficiency, or over consumption of each one. Protein Proteins are macronutrients, and are the building blocks of the body! They’re formed by complex chains of amino acids, of which some are essential (which cannot be made by the body, so must be consumed in the diet), and others are non-essential (which can be made by a healthy body). Proteins make up everything from the fur, claws, immune system, hormones and many more components of the body. While the body doesn’t care where the amino acids come from, we should aim to pick good quality, amino acid rich sources for our dogs – these are found in best quality in beef, chicken, pork and lamb. Sources of inferior, poor quality amino acids include wheat and rice, which we recommend avoiding completely. Proteins build the body and aid repair as they are in a constant state of renewal and degradation. If your puppy consumes too much protein, it may be used as an energy source, but if there is still too much present, it will just be excreted safely through the faeces. If there is a deficiency of protein in your puppy’s diet, your puppy may experience reduced growth rates, anorexia, anaemia, alopecia, infertility, dull coat and brittle fur. Puppies require higher amounts of protein than adult dogs because of their need for growth of new tissues, however this does not mean that owners can safely over-feed their puppies! A small amount of excess protein can be safely excreted, but too much, and excessive weight gain, and rapid growth rates can occur, especially in larger breeds – this is terrible for joints, and can lead to major issues imminently, or further down the line! Fat Fat is another macronutrient, and is super important in a canine diet. They are used as the primary source of energy, of stored in the Adipose tissue for use as an energy source later. Fats are also essential for temperature control, as they insulate the body, as well as acting as a cushion form trauma to major organs. Fats can be saturated, mono-unsaturated, or poly-unsaturated. If you’re into the sciencey side of things, a saturated fat has no double bonds between carbon atoms in its chemical make up, mono-unsaturated fats have one double bond between two carbon atoms in its chemical make up, and poly-unsaturated fats have more than one double bond between carbon atoms in its chemical make up. Dogs have a requirement for two important families of essential fatty acids – omega 3, and omega 6. Omega 3 fatty acids have incredible anti-inflammatory properties, whereas omega 6 can be inflammatory. The modern day canine consumes far more omega 6 than needed in their normal diet and day to day life, so it’s super important to get those omega 3s in the diet, including things like raw egg, raw sprats, raw salmon, tinned sardines, algal oils, fish oils etc. Omega 3 is useful for healthy skin formation, healthy joints during growth, the transportation of fat-soluble vitamins, and modulation of the immune system. As omega 3 is also very important for healthy cognitive function, it’s especially important in puppies! Omega 3 deficiency has also been proven to be linked with aggression in dogs! Findings Here Findings Here Carbohydrates The third of our macronutrients, carbohydrates, come in two types, available, and unavailable. Available carbohydrates are those used for energy. They are digested through the small intestine. The metabolism of these carbohydrates provides glucose for brain function. As there’s only so much storage available for these carbohydrates, over consumption may lead to increased body fat. Unavailable cabrohydrates cannot be digested by dogs, such as soluble and insoluble fibre. Insoluble fibres can aid good bowel health, and keep stools bulky and firm, whereas soluble fibre does the opposite, and helps stools pass easily as it draws water to them. There is no literature available to prove this macronutrients are essential for dogs. Vitamins A, D, E and K These are micronutrients, and are fat-soluble vitamins, meaning they’re transported through the body in fat molecules. Vitamin A is essential for eye and bone health, and can be found in great quantities in eggs, oily fish, carrot, broccoli, and cantaloupe melon. Vitamin D is a hormone that promotes calcium absorption, so play a role in bone health, as well as immune function and cell growth and development. Vitamin D can only be acquired through the diet for dogs, unlike us humans who can get it from the sun. sources include salmon, egg, sardines, liver and mushrooms. Vitamin E is an antioxodiant which protects cells from oxidative stress (damage). Sources include sunflower seeds, wheatgrass, spinach, red bell pepper and pumpkin. Vitamin K contains K1, K2 and K3 – these are all categorised as quinones. These are essential for blood and bone health and development. Vitamin K1 can be found in leafy greens and beef liver, K2 is synthesised by bacteria in the large intestine, and K3 is a common synthetic vitamin. Vitamins B and C Now we move onto the water-soluble vitamins; the vitamins that are transported in water molecules around the body. Vitamin B vitamins have
Here as My Pet Nutritionist, we see customers with pets with a host of different diagnoses. Diet and lifestyle play a huge role in the management of such conditions, and this is no different when your pet has been diagnosed with Hypokalaemia. Find out more about this condition in this blog post, where you can learn what it is, how to spot symptoms, conventional treatments available, and how you can help your dog by tweaking their diet and lifestyle. What is Hypokalaemia? Hypokalaemia is a deficiency of potassium in the bloodstream. We can break the word down into three parts; ‘hypo’ meaning there is not enough of something, ‘kal’ being related to the chemical formula of potassium, and ‘aemia’ meaning in relation to the blood. Potassium is an electrolyte, and is an essential mineral, stored mostly inside cells. It plays a huge role in the body, including keeping nerve function healthy, ensuring the muscles and heart function correctly, and aiding the transport of both nutrients, and waste around the body. Those with hypokalaemia are deficient in potassium, which plays havoc on nerve, muscle and heart function as the change in concentration of potassium disrupts electrical charges and cell signals from passing through the cells properly. Nutrient absorption and waste remove may also reduce. Hypokalaemia mostly affects the nervous system, the cardiovascular system (which is as a result of hypokalaemia of the nervous system, as the lack of electric signalling from the brain to the heart causes irregular heartbeat which can ultimately lead to death), and the musculoskeletal system. This condition can happen in both dogs and cats, but is more common in dogs than it is in cats. Symptoms of Hypokalaemia There are a variety of symptoms you may see in your pet prior to diagnosis, however milder cases may be symptom-free until the deficiency is severe, when symptoms start to show. These symptoms can include: Lethargy/fatigue Vomiting Severe constipation Increased thirst Increased urination Weight loss Muscle wastage Changes to gait (stiffness, posture/head position, and walking on the back of their feet, not the sole) Irregular heartbeat If your pet is showing any number of these symptoms, it is important you seek veterinary attention as soon as possible. Causes of Hypokalaemia So what causes hypokalaemia? This certainly isn’t a straight forward, one answer fits all situation, so let’s take a look at the potential causes of hypokalaemia in pets. In the event that too much potassium is lost from the body due to polyurea (excessively urinating), excessive defecating, vomiting or other bodily fluid loss, Hypokalaemia is a risk. This is often seen as a secondary health complication to chronic kidney disease (CKD), cardiac issues, or cancer, but most commonly with CKD. Those with CKD, cardiac issues or cancer may notice symptoms after some time, as the damage caused on cells in the body causes potassium loss, which is often not replaced in the diet. Findings Here As potassium can only be sourced through the diet, the lack of a properly balanced diet, low food intake (such as those with anorexia), or reductions in the amount of food eaten by the individual each day either due to illness, or weight loss where daily food allowances have been reduced too quickly, can all lead to Hypokalaemia. The recommended amount of potassium per day for a dog is 1g per 15kg (33lbs) bodyweight. For a cat, the recommended daily amount of potassium is 0.33g per 4kg (9lbs) bodyweight. Findings Here Findings Here Findings Here Dogs and cats with metabolic conditions may also be at risk of developing hypokalaemia. Those with diabetes mellitus are among the more common to experience a lack of potassium in the bloodstream. Findings Here The use of some medications such as most cardiac medications which are diuretics can lead to hypokalaemia too, however this is a tricky problem to solve, as the medications with the potential to cause hypokalaemia, are often life saving, and required. Findings Here Diagnosing Hypokalaemia As hypokalaemia is very often associated with other diseases, most commonly CKD, your veterinarian will run a urinalysis – this is where you take a sample of your dog or cat’s urine, which is then analysed in a lab to check your pet’s kidney function. abnormal function of the kidneys could point to hypokalaemia being the reason for your pet’s stiff gait, muscle wastage, or other symptoms commonly displayed by pets with the condition. Alongside a urinalysis, your veterinarian will take a sample of your pet’s blood, which will be analysed in a lab to determine current concentrations of potassium in the blood serum. Abnormal levels of potassium will be easily identified via this blood test. As cardiac issues often come hand in hand with hypokalaemia, due to the lack of ability to send electric signals to the muscle to encourage it to work, many veterinarians will also run an ECG on your pet to ensure their heart is in good working order. This is often carried out following diagnosis of hypokalaemia. Auscultation (listening to parts of the body with a stethoscope) will be carried out, as it should be with any veterinary appointment, regardless of reason. This will quickly check for any signs of arrhythmia, from where the veterinarian may proceed to using an ECG. Findings Here Conventional Treatment Options When treating, or managing hypokalaemia, the ‘conventional’ treatments are very much similar to the natural support you can provide your cat or dog. The ultimate goal, is to raise potassium levels! In the more severe cases, where the pet is extremely unwell, unable to walk, constantly vomiting, defecating and urinating, the pet will be given a potassium rich mixture via intravenous drip. Depending on the condition, and medical history of the pet in question, the veterinarian will be able to determine how fast the potassium drip should be administered – too fast, and the heart may be affected by an irregular heartbeat! Your veterinarian may recommend a specific diet, and will also recommend giving your dog daily potassium
Those with female dogs will most likely deal with seasons at some point in their dog’s earlier years – the recommended time for spaying is between 2 and 4 years of age, unless medically necessary prior to this age. With seasons, comes the risk of phantom pregnancy! This can be quite a trying time for both us and our perfect pooches, so we bring to you, the My Pet Nutritionist guide to phantom pregnancies in dogs! What is a Phantom Pregnancy, When, and Why Do They Happen? Phantom pregnancy in dogs is fairly common other terms you may see are ‘false pregnancy’ or ‘psuedopregnancy’. Phantom pregnancy is a term used to describe behavioural and physiological tendencies similar to those displayed in a pregnant female dog, even though the dog experiencing these changes is not pregnant. They can occur at any age, following an oestrus cycle (commonly known as a ‘season’ or ‘heat’) in an unspayed female. When your dog has a phantom pregnancy following their season, she may have another after the next season, but this isn’t definite – they can occur after every season, or just intermittently. We’ve covered the what and the when, but now onto the why! At the end of your dog’s season, her ovaries begin to produce the hormones necessary for preparing the uterus for implantation of foetuses and pregnancy maintenance. Now, if your dog has been mated, and is pregnant, these hormones are very important, and well utilised. The problem arises when your dog is not pregnant, so these hormones are not required. It takes around 4 to 6 weeks for these hormones to reduce, and for symptoms to reduce, if the dog displays behaviours as if she were pregnant. When these hormones are present without a pregnancy, changes in the body occur, which show as actions mimicking pregnancy. As the dog gets closer to the 4 to 6 weeks after the end of the season, as the levels of hormones start to reduce, false labour is stimulated, alongside mammary gland swelling. Findings Here Symptoms of a Phantom Pregnancy There are a variety of symptoms of a phantom pregnancy in dogs, such as: Enlarged mammary glands (teats); milk may be present Clingy behaviour Lethargy and fatigue Fluid retention Potential vomiting Loss of appetite Nesting Pacing Carrying and guarding toys Symptoms will vary between individuals, as well as severity of symptoms. Findings Here Findings Here Conventional Treatments In severe or extreme cases of phantom pregnancy, your dog may require veterinary attention, where they may be given a hormone treatment. This treatment stops the production of pregnancy hormones, which heavily reduces symptoms, and stops milk production. Findings Here Supplements to Help Your Dog There are a few supplements that could help your dog through her phantom pregnancy. Let’s take a look at these! There’s also one frequently recommended, which we do not recommend, so we will look deeper into why! Homeopathy is a very popular choice when it comes to those in phantom pregnancy. If you choose to use homeopathy, speak to a homeopath or supplier of remedies. The commonly given options for a phantom pregnancy are Pulsatilla and Urtica. Other remedies may also be advised for mood if the dog is in a low mood. Dogs struggling with behavioural effects of phantom pregnancy, who are just not themselves, may require some calming supplements like Scullcap and Valerian. Another supplement that can help in the event of a phantom pregnancy by aiding in the regulation of hormones, is Borage/Starflower oil. This does come with a caveat though – it must be used with caution, and in small amounts as it can cause liver damage, and may also be carcinogenic. This is due to the content of chemicals known as pyrrolizidine alkaloids. Findings Here Findings Here Vitamin B is a great supplement for those in phantom pregnancy, specifically B6, as it helps regress phantom pregnancies in dogs. Magnesium is an essential mineral for our dogs, and it is great to increase in those with phantom pregnancy, as it encourages all round health within the body, keeping all systems running smoothly, and normally. Finally, Theanine helps control arousal levels in mammals. Keeping the arousal levels in check is important in a female with phantom pregnancy, so as to reduce symptoms and keep hormone levels steady. Evening Primrose Oil – Why Should You Avoid It? We mentioned that one popular supplement isn’t one we would recommend – this supplement is Evening Primrose Oil. It can certainly help a bitch in phantom, but why don’t we recommend it? Evening primrose oil is lower in the omega GLA than Borage oil, meaning it has less of an anti inflammatory effect. This isn’t the biggest problem with evening primrose oil though! The main issue is concerning Prostaglandins; a group of fats which have hormone-like effects in mammals. Prostaglandins stimulate the uterine muscles to shed the lining of the uterus which in turn causes increased pain and worsened associated symptoms. Evening primrose oil is what’s known as ‘oestrogenic’ – meaning it promotes oestrus, and makes symptoms more harsh. Evening Primrose Oil also poses a risk to potential epilepsy patients, as it can trigger seizures, so as a precaution, we recommend avoiding it’s use. Findings Here Other Tips to Help Your Dog As well as offering appropriate supplements to your dog, there are some other things you can do to help them through a phantom pregnancy. Lets have a look at some of these: Firstly, your dog will likely be feeling a little unusual, and sorry for herself. Her body is going through some big changes at this time, so the need for more attention and TLC is common. It is so important to be there for her – it can be a bit overwhelming with your dog clinging to you more than normal, but try to stay calm, and give her plenty of love and extra attention to comfort her. Another behavioural aid during this time, possibly one of the most important
Here at My Pet Nutritionist, we don’t like to leave any stone unturned – pun not intended! When it comes to a diagnosis of bladder stones/crystals, it can feel like you’re embarking on a never ending journey. You will find lots of information on each type of bladder stone found in dogs, but this blog post focusses on Struvite Stones. What are Struvite Crystals/Stones? Struvite Crystals are the most common type of crystal found in dogs, and when combined with Urease, a bacteria-produced enzyme, struvite stones are formed. Struvite crystals being present in the urine by themselves, aren’t much of a worry, however when they are combined with the aforementioned Urease, struvite stones do become a problem, and require treatment. Struvite stones also develop as a result of infection by other bacteria types including Proteus, and Staphylococci strains. There are two other names you may see for Struvite Stones, and these are due to their chemical make up; these are: Magnesium-ammonium-phosphate Triple phosphate Female dogs are more at risk of developing struvite stones, with a staggering 85% of cases being seen in female dogs! Dogs with recurring UTIs (urinary tract infections) are also among the most likely to develop struvite stones. Symptoms of Struvite Stones A range of different symptoms may occur if your dog develops struvite stones, including: Blood in urine ‘downward dog’ position indicating stomach pain Frequent urination Urinary incontinence/urinating in unusual places Difficulty urinating Regular licking of the genitals Increased thirst Nausea Findings Here How Do They Form? Struvite Stones thrive in an alkaline environment. When looking at the pH of your dog’s urine using a pH test strip, alkaline urine will show as a blue or purple tone. The healthy range of canine urine is between 6.5 and 7, which is neutral, or very slightly acidic. Anything above pH7 is alkaline. When the body undergoes bacterial infection in the bladder, ammonia is produced, which in turn causes the pH to become more alkaline, allowing the formation of struvite stones to occur. Findings Here Diagnosis of Struvite Stones The easiest way to diagnose struvite stones in dogs, is via X-Ray, however sometimes this isn’t possible due to other parts of the body getting in the way of a clear image. X-Rays use radiowaves, and produce Radiographs (hence those who take the images are known as radiographers!). Struvite stones are radiodense, which means they would show up very easily in X-Rays. In cases where X-Rays are not possible, the veterinarian may use ultrasound on the bladder area. Before scans, the veterinarian may give a coloured liquid to the dog which dyes the stones, making them more visible. The accompanying step to working out the type of stone present, is through urinalysis. Urine samples are needed to find out if any bacteria or crystals are present – this can help determine the type of stone, since bladder stones aren’t very easy to tell apart through imaging alone. If a sample of a stone is taken, this can be analysed by a veterinary laboratory for an official diagnosis of stone type. Findings Here What Can the Vet Do? Much like the removal of another type of bladder stone, the Cysteine Stone, the vet may suggest surgical removal. The surgical procedure is called a Ureteroscopy, during which a very small instrument is passed through the bladder and up the Ureter, pushing the stone out in the process. Alternatively, the pet may be opened up, and large stones causing blockages will be removed by hand. For a non-surgical, less invasive approach, the vet may recommend a procedure known as a urohyrdopropulsion. This procedure is usually most successful on medium to large dogs, and involves two catheters being placed in the dog; one up the urethra, and the other in the urethral lumen. A finger is inserted into the rectum to push against the urethra, causing a build up of pressure and a tight seal. Once a tight seal is made, saline water is flushed through the catheters, and the bladder is palpated, flushing the small stones out. Although this method requires anaesthesia, it is preferred for smaller stones as it is much less invasive than surgery. Findings Here Your veterinarian may suggest a diet change too – however they may wish to sell you a ‘prescription’ dry food diet. This is where fresh feeding is paramount, as dry foods have a low meat content, and low moisture – both of which are essential in abundance for a dog with bladder stones! Let’s take a look at diet, and supplements to help prevent Struvite Stones. Supporting the Body, and Preventing Struvite Stones When it comes to supporting the body with the aim to reduce the risk of recurring Struvite Stones, we need to look at the diet, as well as suitable supplementation. Diet Dogs with any bladder stones, require a high moisture diet! Fresh feeding, whether that’s raw or gently cooked, allows for meals to be suitably high in moisture. You may even wish to ‘float’ the food – meaning you add extra water to it. The other benefit of providing a fresh diet, is the high meat content. Feeding a predominantly meat based diet is essential for those suffering from Struvite Stones as meat naturally encourages a more acidic environment in the bladder. Some ingredients to consider including in your dog’s diet, to promote an acidic environment include: Chicken Pork Beef Eggs Fish Venison Meanwhile, it’s best to avoid more alkaline food like: Broccoli Carrot Cucumber Pumpkin Kale Sweet potato Apple Banana Cabbage Pumpkin We have two recipes balanced to FEDIAF, which are ideal for those with struvite stones – Low Fat Fish and Low Fat Venison. Supplements A number of supplements can be very useful in the combatting of Struvite Stones. Gut Health supplements are one of the most important ones to give, as with almost any condition, a healthy gut microbiome helps. When urea is excreted into the gut passage, it is broken down by the bacterial colonies in
In the modern dog world, there are so many controversies over various food items, from salmon oil to raw eggs to coconut oil to garlic. Here at My Pet Nutritionist, we like to put owners minds at ease, and help you to evaluate whether it is suitable for your pets, using both scientific and anecdotal evidence based on our professional experience. Salmon oil, raw eggs and coconut oil have all been covered within our blog to date, so now it’s time to have garlic in the spotlight! Let’s discover some myths, and truths about this powerful, often useful ingredient! What Is Garlic? This may seem a bit of an obvious section to many, but you may learn something new too! Garlic (Latin name: Allium sativum), is the bulb of a flowering plant, and is a potent addition to foods in the human world, for flavour as well as medicine. It’s closest relatives are onions, leeks, shallots and chives. Humans have consumed garlic since the times of Ancient Egypt. Originating from south and central Asia, and Iran, the vast majority of the world’s garlic production occurs in China. The chemical make up of garlic gives it it’s many beneficial uses in both the human and dog world, however there are caveats when it comes to garlic and dogs! Allicin, ajoene and polysulfides are among the most powerful sulfur containing compounds, alongside lots of useful enzymes, flavonoids (often useful as antioxidants), and saponins (which have great cancer risk reducing properties, as well as being great for lowering blood fat and blood glucose levels. Findings Here Findings Here The Controversy Around Garlic As dog owners, we only want the best for our precious pooches! And that’s where the confusion sets in – safe? Unsafe? My vet said it’s toxic! Someone on an online dog forum said it’s toxic, but another said its ok? The stigma around garlic really is huge! Some professionals will advise against it through no fault of their own – it’s often simply what is taught to them during their education. The controversy all stems from one specific study on garlic, and it’s affects on dogs. Afterall, it’s relatives onion and leek are very much toxic to our pets, so why should garlic be ok when it contains the same active ingredient, allicin? As well as allicin, members of the allium family also contain Thiosulfate. Thiosulfate, in large quantities, can cause a severe type of anaemia in cats and dogs, called Heinz Body Anaemia. If we look at onions vs garlic, we can compare the amount of thiosulfate, and therefore calculate the risk of Heinz Body Anaemia. Onions contain large quantities of Thiosulfate, whereas garlic only contains miniscule amounts, which plays very little to no risk in healthy individuals, and studies were began to work out just how much garlic is safe for our pet dogs. Findings Here So, moving on to the study. The nutrition world was taken by a storm in 2000 when Dr Osamu Yamamoto released a study called ‘Haemolytic Changes Associated with the Appearance of Eccentrocytes After Intragastric Administration of Garlic Extract to Dogs’. You can find the study here. Now, the first point to make, just from looking at the title; garlic ‘extract’ was used. Have you ever baked a cake, using Vanilla Extract? You may notice the extract is extremely concentrated, making it extremely pungent, requiring just a few drips to flavour the entire cake batter! This concept goes for any extract, including that of garlic. The garlic was administered to the dogs in the study in extract form – 1.2mls of this liquid was given to each dog per day for 7 days – likely the equivalent to much more than one would consider giving their dog of anything! More on equivalent amounts shortly. When looking at the health of the dogs in the study, it’s important to note that there was a death rate of 0% – that’s right, a big fat ZERO! No dogs died in the study, nor were there any physical changes to the dogs. When blood tests were analysed under a microscope, despite the lack of symptoms, there was a case of Heinz Body Anaemia. This was the evidence which caused the scientists to make the rather bold statement, that garlic is unsafe for dogs, sending the pet world into panic! Some of the large pet information databases and websites are still under the assumption that garlic is very much toxic to dogs, warning owners to avoid it. Pet food manufacturers were forced to remove garlic from their recipes once this information was released, but further studies were needed to ascertain whether fresh garlic would be safe, since the aforementioned study used the ultra concentrated garlic extract. Let’s take a deeper look at exactly how fresh garlic tolerance levels differ to that of concentrated garlic extract! What Science Has to Say About It As with many preliminary scientific studies, mass panic had set in, opening up opportunities to research the tolerance level of fresh garlic in dogs, after all in unsuitable quantities, anything can be classed as toxic – even water, and we all know water is incredibly important for all living things! When converting the amount of garlic extract that would need to be administered to a medium sized dog for adverse reactions to occur, to the equivalent amount of fresh garlic, the dog would need to consume 35 cloves of garlic every day (or 245 cloves per week!) – not something any owner would dream of doing, we are very sure! Now for the next study by Dr Osamu Yamamoto, titled ‘Acceleration of Superoxide Generation in Polymorphonuclear Leukocytes and Inhibition of Platelet Aggregation by Alk(en)yl Thiosulfates Derived from Onion and Garlic in Dogs and Humans’, published in 2004. This study can be found here. In this study, they used a fresher form of garlic to carry out their investigation, which ultimately found that garlic was in fact good for cardiovascular health, and useful for a
In this blog post, we will look in depth at a popular supplement; salmon oil. Salmon oil does come with it’s controversies among the dog community, so here at My Pet Nutritionist, we bring to you this blog, to help you understand more about salmon oil – what it is, it’s pros and cons, and how to pick a product – not all salmon oil products are equal! What Is Salmon Oil, and How is it Extracted? Salmon is a known as an ‘oily fish’. Oily fish are very high in fatty acids, more specifically Omega 3 Fatty Acids. There are various types of omega 3, but salmon oil is high in two types: Eicosapentaenoic Acid (EPA): reduces inflammation Docosahexaenoic Acid (DHA): aids cognitive health and development The body is unable to produce Omega 3 Fatty Acids, as they are polyunsaturated, so adding omega 3 to our pets’ diets is extremely important. Salmon oil is literally, the oil extracted from fresh salmon, as it’s name suggests. How is it harvested though? One may envision a salmon fillet being squeezed, however this isn’t quite how salmon oil is extracted! There are a few methods for salmon oil extraction. Most traditionally, oily fish is subject to temperatures of between 90oC and 100oC, which releases the molecules of oil to be collected. Another traditional method is through the use of organic solvents and hydrolysis. Organic solvents can be very damaging to the environment, and potentially pose as a health risk too. More recently, enzymatic hydrolysis was found to result in high yields of fish oil and can be carried out at much lower temperatures of 40oC to 65oC. A study published in 2022 found that a new technology using an immobilised enzyme called Alcalase, crosslinked with a polymer known as Chitosan which coats magnetic nanoparticles, is effective at rapidly splitting amino groups from proteins. This method is bioavailable, biodegradable, safe for consumption, and economically beneficial, with the added bonus that the Alcalase enzyme can be reused. The study proved that the oil harvested using this method was of a higher quality than oil extracted through other methods, and the oil was less prone to oxidation. Findings Here Findings Here Then we can move onto our cold pressed salmon oil – something some brands state on their packaging. Cold pressed salmon oil is extracted from fresh fish through means of mechanical force and low heat. The longevity of oil extracted this way is thought to be shorter than using Alcalase, as it can be much more prone to oxidation – we will talk more about oxidation later in this blog post. Cold pressing produces a very low yield, but a high quality oil. Findings Here Benefits of Salmon Oil There are both benefits, and disadvantages to using salmon oil for your pet. Let’s discuss the benefits first, before we move on to the disadvantages. Omega 3 is an incredibly important nutrient to add to your pet’s diet, as we mentioned earlier in this blog post! The anti-inflammatory effect is essential for everything from heart health to cognitive ability and health, to eye health, recovery and prevention from injury, skin health and more. The natural meat based diet of our dogs and cats can be naturally high in omega 6, especially when using meat from farmed sources. Two types of omega 6 (Linolenic Acid (LA) and Arachidonic Acid (ARA)) are inflammatory. Inflammation in the body is bad news – we want to balance this inflammation out or eradicate it completely by adding healthy sources of the anti-inflammatory Omega 3 into the diet. Salmon oil can massively benefit your pet’s brain health, and reduce general inflammation in the body which could be causing anything from itching to heart disease to pancreatitis. Sources of DHA are particularly important for puppies, kittens, and seniors too, as cognitive health and development is most important at these ages. The anti inflammatory properties of salmon oil are also greatly beneficial to pets requiring additional joint support. Findings Here Skin and eye health are also greatly benefited through the use of high quality fish oils and other omega sources. This is once again, linked back to the anti-inflammatory properties of such supplements. Findings Here Human based studies show that salmon oil supplementation can lower the amount of triglycerides in the blood, and increase the level of HDL Cholesterol. As with most things, these studies can be a great backbone for care of our pets too! Triglycerides are ‘bad’ fats which can be linked to heart disease, so reducing these in the blood is essential, and can help to protect the heart. HDL Cholesterol is the ‘good’ stuff, helping also to protect the heart. Findings Here While we are on the topic of blood and how the consumption of EPA and DHA rich supplements like salmon oil can improve it, we can look at blood flow rates. Findings Here As we just mentioned, blood flow can be improved through supplementing the diet with salmon oil, or other sources of DHA and EPA. This can help fertility in those wishing to breed too! The testicular blood flow of a dog has been shown to dramatically improve when given these supplements, which in turn improves semen quality and testosterone levels. Furthermore, for the owners of female pets among us who are pregnant, feeding high quality sources of DHA and EPA can improve fetal development and ultimately lead to healthier litters. Findings Here Findings Here Some animal based studies suggest that supplementation with salmon oil can help in weight maintenance, as the body is ‘satisfied’ with the fat consumption, leaving it unable to accumulate excess body fat. Findings Here Finally, salmon oil is high in Vitamin D. Around 75% of dogs are deficient in Vitamin D, which is essential for regulation of phosphorus and calcium in the body, and in turn keeping bones, muscles and teeth healthy. While offal is a great source of Vitamin D, it doesn’t contain quite enough to meet the required
Here at My Pet Nutritionist, we help customers tackle a host of different health conditions and concerns. Some diseases our customers’ dogs come to us with are common, and simple, others are not so common, and more complex. Exocrine Pancreatic Insufficiency is one of the not-so-common examples of health concerns we have helped customers with. While it is rare, and not tested for as standard, we are beginning to see more and more cases of EPI, so this blog post will be a great educational tool for those who want to learn more about EPI, as well as those who’s pet has been diagnosed with it. What is EPI? EPI, as its commonly called, is shortened from Exocrine Pancreatic Insufficiency. ‘Exocrine’ is the system to do with the body’s enzymes. The pancreas is an important part of the digestive system, and also an important part of the exocrine and endocrine systems. The pancreas is an organ, located in the right side of the abdomen, close to your dog’s stomach. There are two parts to the pancreas – the exocrine pancreas and the endocrine pancreas. The endocrine pancreas releases the hormone, Insulin, which controls blood sugar levels. The exocrine pancreas releases enzymes responsible for food digestion, particularly the macronutrient, protein. In those suffering with EPI, the pancreas is unable to produce enough of these enzymes, which leads to major malnutrition, unless treated daily. EPI is an incurable disease, and requires daily management to keep symptoms at bay. Findings Here Symptoms of EPI There are a number of symptoms associated with Exocrine Pancreatic Insufficiency. Many of these symptoms are common symptoms of other health conditions, which makes diagnosis of EPI quite tricky, but the symptoms can be severe, and in some cases life threatening. Here’s some of the main symptoms you could expect from a dog suffering with EPI include: Rapid weight loss Lack of ability to put weight on Insatiable appetite Chronic diarrhoea Mucus in the stool Vomiting Lethargy/fatigue If your dog has a number of these symptoms, it is extremely important you have your dog assessed by a veterinarian, as EPI dogs can go downhill very quickly. Findings Here Diagnosis of EPI Exocrine Pancreatic Insufficiency is rarely routinely tested for upon first signs of symptoms, and is regularly misdiagnosed. As the disease is quite rare, and little is taught about it in initial veterinary qualifications, dog owners who suspect this disease often have to specifically request for testing for EPI in their initial consultations. So how is EPI diagnosed? There are two tests carried out in those with suspected EPI. A fasted blood test, and a faecal test. Once the sample has been taken, the test used is called a Canine Trypsinogen-like Immunoassay (or cTLI for short!). For this test, pets must be starved for a minimum of 6 hours – this is usually best done overnight. Trypsinogen is a non-activated enzyme; known as a proenzyme. The pancreas of healthy individuals secretes Trypsinogen into the small intestine with other enzymes in the mix, where it converts to Trypsin – the activated form, which is used to digest proteins. It is very much normal for Trypsinogen to be detected in blood tests of healthy animals, because a little Trypsinogen leaks into the blood stream where it is circulated around the body. How do cTLI results differ for those with EPI? The results from a cTLI of a dog with EPI will show as low to no Trypsinogen when analysed. This is because those suffering with EPI have a reduced functionality of the pancreatic tissues, resulting in less Trypsinogen being secreted into the intestine, and therefore less leaking into the bloodstream, if any. Findings Here Another blood test is usually carried out in cases where EPI is suspected, to test for levels of Vitamin B9 (Folate) and Vitamin B12 (Cobalamin). While these vitamins aren’t directly related to the pancreas, they can easily be affected by a poorly functioning pancreas due to the affect EPI has on the microbiome of the gut. Blood serum analysis for Vitamin B12 will be low, as EPI can lead to B12 deficiency, whereas serum analyses for Folate will usually come back in excess. You can read more about high Folate and it’s relationship with low Vitamin B12, and how these are affected by the pancreas in our blog here. Findings Here Let’s move onto the faecal testing side of EPI diagnosis. The test carried out is called a Faecal Elastase Test. This test is for another of the pancreatic enzymes used during digestion, called Elastase. As with all enzymes, Elastase performs a specific job – it’s role in digestion is to help break down fats, carbohydrates and proteins, for use by the body for energy, growth, and cell maintenance. Healthy individuals with a well functioning pancreas will have elastase in their stools, however those with EPI will not produce as much elastase due to damaged pancreatic tissues, so elastase would be lacking in faecal samples. Findings Here Causes of EPI There are various reasons a dog may have EPI – it can be congenital (present from birth), hereditary (genetically inherited), or acquired (through trauma or disease). Congenital and hereditary causes are self-explanatory – it’s important to source puppies from health tested breeding pairs, with no history of EPI in their immediate or extended genetic lines. If you are opening up your heart and home to a rescue dog, there is a small chance of congenital or hereditary EPI, as you don’t know the history of the dog’s genetic lineage, however it is a rare disease, so it wouldn’t be on the forefront of our minds when considering a rescue dog. Should you experience the symptoms listed in this blog post, hopefully our guide will help you and your rescue dog should the need arise. As with many diseases we write about here at My Pet Nutritionist, there are some breeds which are genetically predisposed to EPI, including: West Highland White Terriers German Shepherds Akitas Border
Internal parasitic burdens can be quite worrisome for pet parents – they can affect both our pets, and us humans too, so they’re certainly something to be one step ahead of! Here at My pet Nutritionist, we aim to put your mind at ease, and to help you fully understand the ins and outs of parasites, giving you lots of options to help prevent and control infestations. You can read part 1 here! Welcome to part 2 – Internal Parasites When looking at internal parasites, there are various parts of the body targeted, which we need to look at, including the intestines, (where you can find nematodes, cestodes and protozoa), the lungs, and the heart. Some of these parasites can be life threatening, so it’s important to understand symptoms, prevention, and treatment options. Intestinal Parasites Intestinal parasites are usually referred to by pet owners, as ‘worms’. While some are worms, not all intestinal parasites are worms, nor are all worms equal! Nematodes differ from Cestodes, which differ from Protozoa, so we will delve deeper into each type here in this blog post. Nematodes Nematodes are from the phyla Nematoda, and are your typical worm – they usually look similar to your garden earth worms (though are not actually related!); long and thin, with a squashable texture, and tapered ends. This, of course, is a generalisation, and there are various physical and mechanical differences between the different parasitic nematodes. Here’s the strange thing about nematodes – they can be harmless, and actually beneficial, or they can be parasitic – it’s a very broad phyla! Beneficial nematodes are often used as a means of environmental flea, tick and ant control. These are sold online or from some environmental/gardening shops, and are mixed with water before being sprayed onto the affected area. The microscopic nematodes, now sprayed all over the area, target, and eat the larvae of their target species, which controls pest population! Anyway, getting back to the parasitic kind! Let’s take a look at the intestinal nematodes pet owners may face during their time with pets. Roundworms (Toxocara canis and Toxicaris leonina) Roundworms, also known as Ascarid worms, are very easy to identify in their matured form. If a pet has a burden of these worms, which have matured from their larval stage, they will be very obviously present in the animal’s faeces, or vomit. They are white in colour, usually long (between 4 and 6 inches), thin, and curly – they are often expelled from the body in spirals. The main method of transmission of roundworm to our pets, is through coming into contact with contaminated faeces. Those carrying roundworm, shed microscopic eggs into their faeces, leaving others to come into contact with it. Some insects and other animals, including cockroaches, earthworms, and birds can also carry roundworm eggs, which if eaten by your pet, can pass onto, and mature inside your pet. Puppies can also be born with roundworms, and shed live eggs in their faeces. A question owners often ask, is if they can catch roundworms from their pets – and the answer is yes! Accidental oral contact with your pets faeces can pass roundworms on to you, if your pet is carrying roundworm eggs. Symptoms you may see if your dog has a mature roundworm burden include: Diarrhoea Vomiting Changes to skin and coat Weight loss Bloated appearance to the stomach Visible worms in faeces and/or vomit If your dog has recently contracted roundworm, and it is still in it’s larval stage, it’s unlikely there will be many symptoms, apart from perhaps some loose stools. Findings Here Hookworms (Uncinaria stenocephala and Ancylostoma caninum) The next intestinal nematodes we will look at are Hookworms. As per their name, matured hookworms look like very small, but not microscopic, hooks. They are very thin, no longer than 2cm long, and are white in colour. They can be seen in faeces when they’re matured, but can be confused with undigested food particles, or even small pieces of string. In order to stay inside the intestine, where they are fed and housed in those infected, they have small mouthparts which latch onto the intestine walls where they feed directly from blood vessels surrounding the intestine. There are a few methods of transmission for hookworms in pets – pets can contract them through their mother’s milk as puppies or via the placenta before birth, and they can be orally ingested, or even be contracted through the skin. Hookworm larvae can lay dormant, and reactivate during pregnancy too, so it’s important to run regular faecal samples during pregnancy. Can hookworms transmit to humans? Yes, and no. Larvae can be transmitted in unsanitary conditions, but are rarely transmitted as adults. There is one exception to this however! This may make you shudder, but matured Hookworms can work their way into the human body through the skin, most commonly through bare feet in unsanitary conditions where pets have shed larvae in their faeces. While Hookworm infestations aren’t generally life threatening, they can cause anaemia if left untreated – this is more common in young animals than in adults though. Some symptoms you may notice if your pet has Hookworms include: ‘downward dog’ position in dogs (showing gastrointestinal discomfort) Diarrhoea Vomiting Bloodied stools (due to blood loss when Hookworms detach from the gut lining, as they inject anticoagulants into the localised feeding area) Changes to skin and coat Anaemia, especially in young animals Physical development impairments in young pets Small string like worms visible in faeces Coughing in severe cases If your dog has Hookworms in their larval stage, you may see diarrhoea, but may not see other symptoms, as eggs are microscopic. Findings Here Findings Here Whipworms (Trichuris vulpis) Whipworms, the third nematode sometimes found in our pets, get their name from their shape, much like the other nematodes discussed in this article. If you think of a whip, carried by movie heroes like Indiana Jones, and reduce it’s size to 0.5-5cm – you’ll have
Parasites are always a worry with our pets – let’s face it, our pets touch all sorts on the ground during their walks, sniffing sessions, and play time! It’s inevitable that they come into contact with faeces, urine, slugs, snails and so much more, giving many opportunities for parasites to be picked up, both internally and externally. Here at My Pet Nutritionist we want to help you understand more about parasites, how we can test for them, and how we can help the body rid of them. This is a bumper two part blog, providing you with all the need-to-know information regarding parasites! You can read Part 2 here! Welcome to part 1 – External Parasites Fleas Fleas can be identified as tiny black insects, moving in a hopping form. They jump and crawl around your dog, using a long feeding tube to suck blood from under your dog’s skin. they are very much visible to the naked eye, and another sign of fleas being present, is the dirt they leave behind – this can be identified as black matter in patches across the skin of the dog, at the base of hair follicles. Fleas can be picked up out on walks, or from communal dog establishments when in contact with another dog with fleas, or wildlife with fleas. There are different types of fleas, which target different animal species, some live happily on dogs and cats too, but others can only survive on their intended species, for example hedgehog fleas can only survive on hedgehogs. Cat fleas and dog fleas are the ones most commonly seen in pet households. They can also bite their humans too! If flea infestations are left for too long, the pet can become anaemic (particularly common in puppies), and also suffer with hair loss. Later in this blog post, we will discuss the dangers of using isoxazolines (chewable pest treatments) and spot-on treatments for our pets. Sometimes severe infestations do require one of these products to get them under control, as well as professional house exterminators, but we recommend avoiding these products unless it is as a last resort. Naturally, you can help prevent fleas through the use of selected essential oils (take extra caution with cats when using EOs) and neem oil on the pet, and feeding fresh garlic to dogs (though avoid feeding garlic to puppies under 6 months, and any Japanese breed as these are susceptible to allicin poisoning), as well as another herbal flea prevention supplement. There are many natural topical and internal products on the market, specifically for their target species, whether that’s cat or dog, so using these in a layered approach may give you the best chance of staying flea free! If your pet was to get some fleas, rubbing a thick layer of shampoo onto their dry coat, and leaving for 10 minutes before rinsing out using a comb can really help control the infestation. You can also purchase electric flea-zapping combs which can have great results! In severe cases, food grade diatomaceous earth could be sprinkled onto the coat, however this is extremely drying on the skin, and can be lethal if inhaled. You will also need to focus on steam cleaning your soft furnishings, carpets etc, and clean the house regularly, making extra sure to clean any small, potentially moist nooks and crannies, and wicker items as fleas seem to love these areas! Findings Here Findings Here Ticks Ticks get a really bad reputation – and for good reason, especially in some countries outside of the UK. Ticks can be identified as having a bulbous body, with very small head, and 8 legs, protruding from the head area. When they’re attached to your pet’s skin, you will be able to see the large rounded body (the larger the body, the more the tick has fed), with some legs seen very close to the skin. Ticks need to be removed as soon as possible, as they can carry a range of diseases – anything from Lyme disease (which is the most common tick bourne disease in the UK, though isn’t very common I itself) to disease leading to Alfa Gal Syndrome in humans, and paralysis in the host in other countries. They really can be nasty little creatures! To remove a tick, simply grab a tick removal tool and follow the basic instructions. They’re usually fail safe, and easy to use. If by chance, you do get the head stuck in the pet, these usually work their way out in time. To transmit Lymes Disease, ticks have to be attached for 36-48 hours, however some species of ticks carrying more sinister diseases in countries outside the UK can transmit disease quicker, so it’s super important to check your pets twice a day, and after every walk. You can read more about types of ticks, tick removal, and tick prevention in our blog dedicated to ticks here! Mites Mites come in various forms. The most common ones we see, are Mange (of which there are two types), harvest mites, and ear mites. Let’s take a look at some of these. Mange Mange presents as large areas of hair loss and scabbing. In severe cases, dogs can become completely bald. To test for mange, your veterinarian will take a skin scrape – a sample of the skin’s microbiome, which is analysed under a microscope for mite activity. Each type of mite is a different shape, so the type of mite can easily be diagnosed. Sarcoptic mange is often referred to as Scabies. Sarcoptic mange mites tend to live on the skin’s surface, and tend to be contagious. Ivermectin is the treatment often prescribed by veterinarians to battle sarcoptic mange, however there are some potential complication to using this, which we will discuss later in this blog. Some medicated, anti-seborrheic shampoos, are often used too. There are some natural options that may work in helping fight sarcoptic mange mites, including neem oil, turmeric, and some select essential
Malabsorption is something we see fairly frequently in dogs here at My Pet Nutritionist. It can be quite scary for pet owners to witness, but there may be some things we can recommend to help these pets. This blog post will explain what malabsorption is, what causes it, and how you can support the body through diet and supplements. What is Malabsorption? Malabsorption is a condition that affects the patient’s ability to efficiently absorb nutrients from food sources. The dog may be consuming a perfectly balanced diet, but still unable to benefit from the nutrition it provides. This is down to underlying problems between the small intestine, and the pancreas; these underlying problems can be a multitude of ailments, so further investigation into potential underlying issues is paramount and working with your veterinarian to discover these, is important. Regular visitors to our blog, may notice we often list breeds who are commonly predisposed to each condition we talk about, however when it comes to malabsorption, there is no specific breed predisposed. This is down to the fact that different breeds will be predisposed to different underlying conditions, and it very much depends on the condition diagnosed, which is causing the malabsorption. Symptoms of Malabsorption There are a variety of symptoms you may notice if your dog has malabsorption. Here are some of them: Pica (consumption of unusual/inedible items) Weight loss, often rapid Lethargy and fatigue Insatiable appetite/extreme hunger Loose stools and gurgling stomach Flactulance Nausea and vomiting Reduced coat condition If these symptoms are present in your dog, please seek veterinary advice as soon as possible as investigations are the important first step in helping your dog with malabsorption. Findings Here Causes of Malabsorption There are many underlying conditions which could lead to malabsorption. We will go through some of these, and give a brief description of each one. You may wish to take this article with you to your veterinary appointment as some of the conditions are not routinely tested for. Inflammatory Bowel Disease (IBD) Inflammatory Bowel Disease is something we talk about, and see a lot here at My Pet Nutritionist. It seems to be very common in lots of dogs who have poor gut health. Those with IBD have inflamed bowels due to the penetration of cytokines and inflammatory cells to the gut and stomach, causing an abnormal immune response. This then has an effect on the lymphatic system, which in severe cases causes Lymphoplasmacytic Gastritis. When the digestive system is inflamed, nutrient absorption becomes very difficult, causing malabsorption. You can read more about severe IBD here. Findings Here Small Intestinal Bacterial Overgrowth (SIBO) We see a lot of patients with SIBO. Those suffering with bacterial overgrowth in the small intestine will often suffer with malabsorption. This major imbalance in the microbiome means that some bad bacteria out-competes the good bacteria required as part of a health microbiome. The bad bacteria, of which there are too many in those with SIBO, often release toxins, and massively interfere with the absorption of nutrients. Findings Here Findings Here Intestinal Blockage Blockages of the intestine are a very common cause of malabsorption. These often go unnoticed, especially if owners don’t realise their dog has swallowed something undigestible, or if the dog is unable to tolerate bone as part of their raw diet. When the bowel is obstructed, food is unable to pass through the intestine, and therefore nutrients are not absorbed from the food, leading to severe weight loss, as part of malabsorption. Blockages causing malabsorption require surgery for removal. Findings Here Exocrine Pancreatic Insufficiency (EPI) This disease is a severe one, and is often not checked for routinely by veterinarians. It may be something to bring up with your vet during your appointment, as though its relatively rare, we are starting to see a few more cases here and there. Your vet may need to do some reading up on it before advising. EPI is occurs due to the pancreas producing less digestive enzymes than needed. Because there is a deficiency in digestive enzymes, foods consumed are not appropriately digested, and therefore nutrients are not absorbed, causing rapid weight loss, large volumes of poor stools, pica, and a variety of other symptoms of malabsorption. This condition is not curable, and dogs diagnosed with it will require regular veterinary check ups, and daily enzyme supplements. Findings Here Findings Here Parasitic Burdens Parasites are another fairly common cause of malabsorption because the parasites compromise the health of the gut, and also syphon nutrients for themselves. Severe infestations of intestinal parasites, or severe cases of giardiasis (where cysts form on the gut following infection from the protozoan parasite Giardia) can lead to malabsorption and severe malnutrition, causing many of the symptoms listed above. It is important to send a faecal sample to a faecal testing laboratory on a regular basis, preferably every 12 weeks, to catch any worm eggs or juvenile worms before large infestations are able to occur. Regular natural worm prevention is also essential for those who tolerate it. You can learn more about natural pest control in our blog here. Findings Here Food Sensitivities Food sensitivities are probably the most common ailments in our customer’s dogs. We deal with a huge number of dogs with food sensitivities, many of which have weight loss as a symptom. Food intolerances are generally coupled with poor gut health, especially cases linked to Leaky Gut Syndrome, whereby the integrity of the gut wall is compromised. When the gut is in bad condition, the microbiome becomes unbalanced, making nutrient absorption tricky. Findings Here Intestinal Growths and Tumours Much like those with an intestinal blockage due to consumption of inedible items, growths and tumours in the intestinal tract are a blockage risk. When these growths or tumours develop and grow, they can create a total blockage of the intestine, which stops nutrients from being absorbed efficiently. While these can be removed by surgery in many cases, some require part of the bowel to removed
The humble blueberry; small, sweet, juicy … and incredibly beneficial! Here at My Pet Nutritionist, we are big fans of feeding fresh, and adding beneficial, fresh ingredients to the dinner bowl. Blueberries are one of those tiny powerhouses we often recommend adding to your pet’s bowl. Find out all about the brilliant blueberry, and all it has to offer in this blog post. The Blueberry – Nutrition Let’s take a look at the nutrition, appearance, and texture of the blueberry. Blueberries are small, dark blue-purple coloured, round berries. They are very juicy, as they’re 85% water! The skin is soft, smooth and digestible, with a little crown on the top, where a stalk would have once attached them to the plant. They are quite sweet to taste, however some can be a little tart – generally speaking, the smaller the blueberry, the more tart it is, so if your dog prefers the sweeter fruits, aim for the larger berries! As well as being super high in moisture, blueberries are a great source of dietary fibre compared to other berries, high in Vitamin C, high in Vitamin K, and high in both Potassium and Manganese. Blueberries are 9% carbohydrates in the form of naturally occurring sugars, so it’s important to feed in moderation. All in all, the blueberry is a relatively low calorie fruit choice, with added benefits, which we will discuss next! What Benefits Does the Blueberry Bring? There are many health benefits to feeding blueberries – these go for us humans too, so why not share them with your dog?! Fantastic Antioxidants The biggest benefit to feeding blueberries, is their incredibly powerful antioxidant complex! Blueberries are one of the best antioxidant foods. To understand a little more about antioxidants, and why they’re important, we need to learn about Free Radicals. Free Radicals are unstable molecules found in the body – if you want the nitty gritty science stuff, a free radical is an atom, molecule or ion which has an unpaired electron in it’s orbital. Due to the lack of a paired electron, the molecule becomes extremely unstable and volatile, which in turn has major negative effects on the body. Free radicals cause damage to healthy cells through oxidisation, which leads to cancer, premature ageing and can be linked to many other diseases within the body. Now you know a bit about free radicals, you can probably see why it’s important to rid the body of them. This is the job of antioxidants! Findings Here Findings Here The term ‘antioxidants’ is actually quite broad. There are various types of antioxidants, but the one most prominent in blueberries, giving them their awesome properties, is the ‘flavonoid’ family. When looking at flavonoids in blueberries, we can be even more specific! The group of flavonoids in blueberries is the ‘anthocyanins’. Studies show that consumption of wild blueberries directly increases antioxidant levels in the body! Findings Here Findings Here Findings Here Anti-Aging and Anti-Cancer Properties Now we understand the general benefits of antioxidants, we can look at other parts of the body which need antioxidant action to stay healthy! Free radicals cause oxidative stress, which affects DNA health! Damaged DNA is bad news – this occurs naturally to nearly every cell in the body, all day, every day … it’s a part of ageing! Not only does DNA damage lead to general ageing, it also leaves the body more vulnerable to cancer. Here’s where our important antioxidants come in – we want to reduce the free radicals in the body, to reduce DNA damage, slow ageing, and reduce the risk of cancer. Findings Here Findings Here Heart Happy Berries – Cholesterol Protection Cholesterol in the body plays an important role, but high cholesterol, or oxidised low density lipoprotein (LDL) cholesterol can lead to heart disease. So how does protecting cholesterol help, when most of the body’s cholesterol is the ‘bad’ LDL type? Well, protecting it from damage makes it less of a risk! As oxidised LDL cholesterol is what leads to heart disease, and free radicals are what causes the oxidisation, providing a good quality antioxidant reduces the risk of damaged LDL cholesterol, and in turn reduces the risk of heart disease. Findings Here Findings Here While there is not many studies into the heart failure rate in dogs, with data on the reduction of heart attacks in those being fed anthocyanins, there is a human based study with quite staggering results! Study participants with a higher intake of anthocyanins had a 32% reduced risk of heart attacks! Cognitive Function You may have seen other My Pet Nutritionist articles regarding cognitive function, and the importance of omega 3 in the diet to aid this by reducing inflammation on the brain. This is incredibly important, however the destruction of free radicals is also incredibly important for brain health and cognitive function. As all cells in the body are affected by free radicals, and subsequent oxidation, brain cells are no exception! Different parts of the brain have different uses. Antioxidants tend to have the greatest affect in the health of areas associated with intelligence, and also act on ageing neurons, which causes greater general brain function as individuals age. Some studies show an improved memory too! Findings Here Findings Here Findings Here Findings Here Muscle Recovery and Function The final part of the body commonly affected by oxidative stress through damage by free radicals, is the musculoskeletal system, specifically the muscles. During, and after strenuous exercise (for example after a long walk, or dog sport like agility or flyball), oxidative stress occurs in the muscles due to inflammation. This is how muscular soreness happens. Reducing oxidation of the muscular cells may help to reduce muscle fatigue, and stiffness post exercise. This is an area which still needs further research, and more studies, but one studies so far show positive data, supporting antioxidants being useful for muscle recovery post exercise!

If you use social media, or dog health forums, you may have heard fellow pet parents mentioning ‘cool’, ‘warm’, ‘hot’ and ‘neutral’ foods. The recommendation for itchy dogs, tends to be to use ‘cool’ foods if we look at nutrigenomics and the principle of food energetics. Here at My Pet Nutritionist, we wanted to dedicate a blog to ‘cool foods’, and feeding them to itchy dogs, so we hope this blog post answers any questions you may have! Yin-Yang Nutrition Yin-Yang Nutrition is a Traditional Chinese Medicine concept which categorises foods into four pillars – Cool, Neutral, Warm and Hot. Which category each protein is linked to, depends on that food’s characteristics. Balance is the basis of Yin-Yang Nutrition, and is what determines whether an individual should eat cool, neutral, warm or hot food sources. Lets take a look at the clinical symptoms of and abundance and deficiency of yin and yang. If your dog has an abundance of Yang…they have excessive heat as they’re unable to counteract warming properties. Heat needs to be removed, so cool foods are required. Clinical signs of dogs with an abundance of yang include: Acute onset, usually at a younger age Short course No general weakness High fever Hyperactivity Elevated heart rate Strong heartbeat Tongue discolouration – usually red or purple If your dog has a deficiency of Yang… the body lacks warming properties enough to combat the normal level of Yin in the body, so warming foods are required. Clinical signs of dogs with a deficiency of Yang include: Chronic onset, usually at an older age Long course Low body temperature at the extremities Loose stools Urinary incontinence Swelling of the limbs due to trapped body fluids (Oedema) Chronic weakness and pain Generalised weakness Discolouration to the tongue – usually pale Weak heart rate Deep heart beat Infertility If your dog has an abundance of Yin… they have excessive coldness, and are unable to counteract cooling properties. Warmth needs to be gained, and cold removed, so hot foods should be given. Clinical signs of dogs with an abundance of Yin include: Acute onset, usually at a younger age Short course High pain levels No general weakness Swelling of the limbs due to fluid retention (Oedema) Loose stools Slow heart rate Strong heart beat Tongue discolouration – usually red or purple If your dog has a Yin deficiency… the body lacks cooling properties, enough to combat the normal levels of Yang, so cooling foods are required. Clinical signs of dogs with a deficiency of Yin include: Chronic onset, often at a younger age Long course Generalised weakness Fever, but not high fever Anxiety Increased thirst Seeks cool areas Tongue discolouration – usually red and dry Increased heart rate Findings Here Findings Here If your dog is in perfect balance, then the above clinical signs will not be apparent, and the dog will be healthy, with pink, moist tongue, normal activity levels, a formed stool, no pain, and normal heart rate and beat. When looking at the Yin-Yang theory, these dogs should eat a balance of ‘Cool’ and ‘Hot’ foods, and unlimited ‘Neutral’ foods. Findings Here You can learn more about general Traditional Chinese Medicine here. Which Foods are Cool? So, when we speak of ‘cool proteins/foods’, what do we actually mean? Which foods are cool? Protiens Duck Frog (perhaps not the easiest to source in most countries, but frog meat can be used as part of a balanced DIY raw diet) Rabbit Cod Scallops White fish Eggs Pork turkey Plants Broccoli Cauliflower Turnip Lettuce Cucumber Seaweed/kelp Dandelion Spirulina Swiss chard Wheat grass Button mushrooms Apple Banana Melon Supplements Flaxseed Sesame seeds Itchy Dogs and Cool Proteins Itchy dogs may benefit from being fed cool proteins, in some situations. It can very much depend on the reason the dog is itchy – food intolerances/allergies, or environmental allergies. The problem with food related itching, is that the immunological response to a protein can vary between sources, and isn’t necessarily down to heat in the body. In these situations, working on gut health is important, as is working out which proteins need to be eliminated from the diet. If the dog is suffering with environmental allergies however, the body’s response to an environmental allergen is inflammation, which can often be linked to imbalances in the Yin and Yang. Dogs with itching and allergies tend to have excess Yang. The main element of this, and what we will focus on in this blog, is seasonal allergies. When a dog presents with seasonal allergies, a number of conditions can occur, which can be down to heat invasions with damp elements. Conditions often coming hand in hand with seasonal allergies, as well as occurring independently include generalised itching, eczema, hot spots, interdigital furunculosis, dermatitis, and seasonal alopecia. Dryness during old age can also cause coat and skin changes which present as itching. For itchy dogs suffering with these conditions, feeding a cool diet may be hugely beneficial to getting on top of the itch. While alternative therapies are often frowned upon by the medical community, there are studies to prove the efficacy and safety of Traditional Chinese Medicine, and other natural therapies. Findings Here Findings Here By looking at the dog’s clinical signs closely, you may see some of the less obvious signs of a Yin-Yang imbalance. Once an imbalance is detected, you can tailor the dog’s diet to include more cool proteins, and eliminate any warm or hot ones. As the cooling proteins have an anti-inflammatory effect for those with inflammation in and on the body, the reduction in inflammation will help reduce itching. Ultimately, the Yin-Yang balance will align, and the body will have equal amount of both Yin, And Yang. Theoretically, this will present as perfect health, and eliminated itching. It’s important to bear in mind, that itching could be caused by food sensitivities, which can require a more western approach, and a full elimination diet to be completed. Some evidence does suggest that pruritic dermatitis,
