The primary two functions of the skin is to act as a protective barrier and an immune barrier, between the body and its external environment, it keeps everything in, and prevents the entry of pathogens and allergens. Here at My Pet Nutritionist, we have heavily focussed on the skin function and allergies so let’s take a look. A defective skin barrier is a key feature of the chronic inflammatory skin disease, atopic dermatitis and it has been noted that the protein filaggrin has a pivotal role in skin barrier function. Mutations with the FLG gene, which encodes filaggrin, strongly predisposes to conditions including atopic dermatitis and secondary allergic diseases. Whilst we always find these revelations in human literature, we have found that this also applies to dogs. So, let’s take a look at filaggrin in a little more detail and how there is a possibility that the skin issues faced by your dog may have a genetic origin. What is Filaggrin The term filaggrin, derived from filament-aggregating protein, was first coined in 1981 to describe a class of structural protein that had been isolated from the stratum corneum (the outermost layer of the epidermis of the skin). Filaggrin is formed from the breakdown of profilaggrin, a protein contained in the granular layer of the upper epidermis. Filaggrin is vital for skin cells to mature properly into the tough, flat corneocytes that form the outermost protective layer of our skin known as the cornified cell envelope (CCE). It does this by binding together the rigid keratin filaments that form a structural skeleton within the cells. As a result, the cells collapse and become flattened. The CCE is constantly renewed by new cells formed in the basal layer of the epidermis. These gradually work their way to the top of the skin layers where they become corneocytes. They will then shed. Surrounding the corneocytes you will find a layer of lipids, which coat the CCE, keeping the skin waterproof, protected and supple. This also provides a protective layer, keeping out irritants and allergens. Without filaggrin, the CCE does not form correctly. Corneocytes dry out, and the lipid layer is lost. This results in dry, cracked skin and a permeability to the skin. Atopic dermatitis is characterised by these symptoms, and data has revealed an association between loss of functions of the filaggrin coding gene and this condition. In short, these conditions are more commonly noted in those with a mutant gene, than those without a mutant gene. What is particularly interesting is that the environment plays a role, not only in developing atopic disease, but also directly in FLG expression. It is regularly noted that exposure to irritants can reduce epidermal FLG levels and lead to an acquired filaggrin deficiency. The FLG deficiency, be it genetically determined or acquired, causes an altered epidermal structure and an impaired barrier function. Sadly, this allows penetration of environmental allergens into the skin, including house dust mites, pollen, bacteria, irritants, and toxicants but it also results in sensitisation of the host. The resultant alteration of the epidermis by way of increased pH, altered lipid secretion, modification of keratinocytes and reduction of antimicrobial peptides also then paves the way for the perfect environment for other bacteria and fungi to thrive, leading to recurrent skin infections, which you’ll have likely observed in cases of canine atopic dermatitis. Environmental and Inflammatory Factors known to alter the amount of Filaggrin: Humidity It seems there is a correlation between indoor humidity and disease severity. In human studies, in those children with atopic dermatitis and FLG mutations, their skin lesions are more often located in air-exposed skin areas. Interestingly, children with atopic disease experience a reduction in disease severity after one month spent in a humid climate. It seems that filaggrin and more filaggrin proteolysis is required in a dryer environment and for that reason, it is often concluded that children predisposed to atopic dermatitis should be encouraged to increase their indoor humidity. Findings here Mechanical damage Mechanical damage includes stretching, compression, and friction on skin cells. It not only affects the barrier function of the skin but also induces various immune responses, triggering inflammation at the site of the stress on the skin. For example, scratching of itchy lesions exacerbates the skin inflammation in atopic dermatitis. This increase in inflammatory mediators has been seen to down regulate filaggrin expression. Skin Irritants Studies have demonstrated that profilaggrin expression can be down regulated after application of experimental sodium lauryl sulphate (SLS). In the 6 hours post exposure, it was noted that SLS in fact induced skin barrier defects. Findings here SLS is what’s known as a surfactant. This means it lowers the surface tension between ingredients, which is why it’s used as a cleansing and foaming agent. You will find SLS in a range of human products and may find it in some dog grooming products. It is generally what makes them foam. Human Products: Hand sanitiser Makeup remover Liquid hand soap Shampoo Conditioner Styling gel Bubble baths Dental care products like toothpaste Anti-itch creams Sunscreen You may also find it as a food additive in certain products, it is used to mix acids with other liquids, or as an emulsifier or thickener. Dog Grooming Products: Shampoo Conditioner Detangler Conditioning balms Deodorising sprays Cologne It is also worth noting that some shampoos specifically prescribed or advertised for use in atopic disease also contain SLS, amongst other ingredients. The issue is that when products reduce filaggrin expression, it disrupts the skin barrier, making it permeable to other toxicants and irritants, creating a vicious cycle. What you choose to apply to your dog’s coat and skin is just as important as what you put into their body through their diet. Not only that, but whilst you may not be applying human products directly to your dog, they may come into contact with them through exposure to soft furnishings or you. In the hopes to create a mechanical barrier, without harsh chemicals being used, there are certain topical products
Have you ever noticed that the wolves found in Yellowstone are rarely obese? Even the alpha males, who in theory could have access to all the kill they choose, maintain a lean weight. Do they perfectly balance their calories in with their calories out? Whilst not impossible, it’s a slight stretch of their intuition and it demonstrates on a simplistic level, why the CICO model doesn’t really answer enough questions when exploring the concept of obesity. In our last My Pet Nutritionist blog article, we explored a range of ideas that can contribute to obesity in pets, but there are many more schools of thought, so we thought we’d explore another in a separate article. One of them being hormones. All of the fat found in cells is stored in the form of triglycerides. Fatty acids are converted into triglycerides for storage and then for fat to be used as energy, they are freed back into fatty acids. Getting fat is the process where triglycerides are created more quickly than they are broken down. This flow of fatty acids is regulated by a range of enzymes and hormones. This isn’t surprising when we consider the role of growth hormone, it is what drives the growth of children and adolescents. If you are considering bodybuilding, steroid hormones are used to increase bulk and if you take a trip down memory lane, chickens were injected with hormones in the 50’s to increase their size too! Findings here It seems that, on a simplistic level, certain hormones cause fat cells to suck up fatty acids more readily than they otherwise would or slow down the rate at which triglycerides are converted back. Both oestrogen and testosterone have been shown to decrease the rate at which certain cells take up free fatty acids, which results in keeping the fat cells relatively small (and why in humans you will notice differences in fat gain between males and females). This is why after neutering your pet, you are advised to monitor their weight as more often than not, they gain weight. This issue here is demonstrated by a study conducted in the early 1970’s. A professor named George Wade wanted to explore how animals regulated their fat supplies. He had two groups of rats and removed their ovaries. The first group then was given free access to food and they could eat as much as they desired. They subsequently ate more than they had before the surgery and became obese. The second group were restricted to the same number of calories they had eaten before the surgery. Their environment was also kept the same. But this second group too became obese it just occurred through a different mechanism. They simply became less active. With the removal of the hormones, it is thought that the uptake of the free fatty acids was unregulated, resulting in more fatty tissue. With the drop in lipid levels, group one sought to replace the circulating levels with more food, but with the absence of food in the second group, they simply became less active to account for the shortfall. The implication of hormones in fat regulation is also demonstrated when lesions in the brain disrupt the hypothalamus. The ventromedial hypothalamus is one of the most hormonally active areas in the brain, and lesions here have resulted in the development of obesity. Leptin largely exerts its influence in the hypothalamus and leptin has a crucial role in regulating food intake and maintaining metabolic homeostasis (balance). Being another hormone, leptin is secreted mainly by adipocytes. Plasma leptin levels are significantly associated with body mass index and total body fat. It is generally accepted that total fat mass is the strongest predictor of circulating leptin. The discovery of leptin made it clear that adipose tissue (fat tissue) is not only a regulator of body weight but also an endocrine organ with feedback loops between the brain and peripheral tissues. Leptin levels decrease during fasting or energy restriction and increase during refeeding, overfeeding and sometimes during times of stress. Several metabolic and hormonal factors influence the synthesis and secretion of leptin in the body such as cytokines, cortisol, catecholamines, fatty acids, glucose, and insulin. Which brings us to another hormone that is intricately involved in obesity in our pets. Insulin Insulin is deemed an anabolic hormone; it works to accelerate the rate at which nutrients are put together to make new tissues. Insulin is well known for its role in clearing glucose from the bloodstream and regulating blood sugar balance. We’ll use the dry fed dog to explore this a little further. When carbohydrates are digested by the dog, they are broken down into glucose. Carbohydrates can be complex (being longer chains of molecules and taking a little longer to be broken down) or simple (broken down quickly and easily). Ultimately, when they exit the digestive tract and find themselves in the bloodstream, they exist as glucose. When blood sugar levels start to creep up, insulin is called to action. Insulin is like the porter in the hotel; it shuttles glucose out of the bloodstream and opens the doors of where it needs to go. This can be to cells or muscles to be used as energy, but if it isn’t needed there, it can be stored (in adipose tissue). Think of it like when you’ve got an early check out and leave your luggage at reception until you’re due at the airport. But what insulin also does is blocks the conversion of triglycerides back; this makes absolute sense as it wants to prioritise the use of glucose as energy to get it out of the blood stream! But what this means is that insulin is in fact a fat regulator. Now we know glucose can be generated from non-carbohydrate sources through gluconeogenesis, but the issue for the dry fed dog, is that these diets often score incredibly high on their carbohydrate content. Due to the range on the market, it can be anywhere up
It always takes a couple of years for data to start filtering through, but in 2018, a survey of veterinary professionals believed that rates of obesity are increasing year on year. It is thought that 51% of dogs and 44% of cats in the UK are overweight. That is just over half of the population of dogs and nearly half of the population of cats. These numbers are up on the last data sourced in 2015. 100% of veterinary professionals are concerned about the prevalence of obesity and the health issues it can lead to. In the words of James Smith PT, we’d love to tell you it’s as simple as a calorie deficit, but here at My Pet Nutritionist, we know that obesity is in fact a multifactorial condition, which can make it a hard nut to crack. But we also know that the health of your pet depends on it. So, we’re not about to grab a hammer, instead we’re going to take a look around the cookware store and find the right nutcracker to do the job. Fancy a trip? The Health Issues Associated with Obesity: Being overweight increases the risk factors for developing: Cancer Diabetes Heart disease Osteoarthritis and degeneration of joints Urinary bladder stones Surgery complications Respiratory difficulties Kidney disease All things considered, its easy to see why obesity significantly reduces lifespan and why it is something that really needs to be addressed. What is obesity? Obesity is defined as an accumulation of excessive amounts of adipose tissue. It is generally a state of positive energy balance. When food is ingested, it is digested and metabolised. The body uses the nutrients it needs and converts the main macronutrients to energy. All energy in the body is produced by the breakdown of ATP, adenosine triphosphate. ATP is found in all cells in all the body, but as it is a large molecule, not so much can be stored. In nearly every living thing, this energy comes from the metabolism of glucose. There are three relevant energy systems. 1. ATP-P This is where the body uses all the ATP it has stored in its cells. This is the simplest energy production process; and if we were to consider it in human terms, this is the system that your 100m sprint would utilise. 2. Glycolytic System This system runs on glycogen, which is stored glucose. In human terms, this system provides moderate power and moderate duration. Both the ATP-PC and Glycolytic system are anaerobic, meaning they don’t require oxygen to produce ATP. 3. Oxidative Syste This system, as its name suggests does involve the use of oxygen to product ATP. This system cannot produce energy as quickly as the other two, but it can produce it continually and for a longer duration. This system can use stored carbohydrates and fats for fuel. In human terms, this would be the system that the marathon runner would access! So, in short, glucose is used as energy, but unused glucose can be converted to glycogen to be stored in the liver and muscles. If there is still leftover, then it is converted into fatty acids and stored in adipose tissue. This makes evolutionary sense; there would be a reserve during periods of low food availability. However, as you have noticed, fat too can be used as an energy source, and protein can be broken down into amino acids and then converted to glucose in a process known as gluconeogenesis. This is where the calorie in, calorie out idea comes from. An overabundance of any of the three macronutrients, can be converted into fat for later use. And the idea that obesity comes from reduced activity comes from the reasoning that those reserves aren’t actually used. On a simplistic level, this makes absolute sense and for the pet who is starting to look a little more round than usual, a simple reduction to their daily intake or a longer walk, may just tuck that waist in a little more. But there are many more factors at play here. Fat is the New Norm Do you know your pet is overweight? In an 8000-household study, 68% of surveyed owners report thinking their pet is the perfect weight. 67% of surveyed owners did not see obesity as a concern. Interestingly, a recent report from the NHS in the UK identified that 67% of men and 60% women were overweight or obese. 20% of Year 6 children were also classified as obese. Findings here Whilst we acknowledge there are faults in BMI scores, it still highlights a valid point. Sadly, pet obesity has many parallels with human obesity and according to the NHS, fat is the new norm for humans. As we know, we learn from experience and so, if we are consistently exposed to something, it becomes accepted. If we are consistently exposed to round pets, without a waistline, do we accept it? But, our pets need a waistline. They should tuck-in behind their ribs, and underneath. Whilst you shouldn’t be able to see their ribs, you should be able to feel them. They should not look rectangular from any angle, side or above. What treats are you offering your pet? Whilst for us humans, a decadent chocolate pot may be a weekend treat, dog treats have somewhat lost their novelty. Treats can be a useful resource during training, and in some cases, high value are necessary, but for some, treats are used as a way to prevent feelings of guilt when pets are being left home alone. Depending on how many times you leave the house, these can soon add up! 1. Table scrap We’ve all been there, those eyes looking up at you whilst you’re eating. Whilst that cubic inch of cheese only warrants 68 calories of your daily 2500 (call it 3%), for your 9kg Scottie Dog, that’s nearly 20% of their daily calorie allowance. If begging at the table is an issue, it is possible to remove the pets to
Here at My Pet Nutritionist, we get asked about vaccines a lot. We have plenty of data and scientific, validated research on the core DHP vaccines, but then we have the supposed concern of Leptosporosis, so here is our presentation of the facts. Leptospirosis is a bacterial infection with around 250 serovars. It affects dogs, most mammals and marsupials and even humans. Leptospirosis can be found worldwide but is most prevalent in warm humid countries that experience heavy rain fall. The bacteria can be found in puddles, stagnant water and moist soil that has been infected by the urine of an infected animal. Leptospirosis is transmitted by drinking infected water, through open wounds and through mucus membranes like the eyes and nose. Symptoms can range from mild, subclinical infection with little to no symptoms at all, to multi-organ failure and in some cases death. Signs of leptospirosis are fever, muscle tenderness, vomiting, diarrhoea and jaundice to liver and kidney failure. In 80-90% of cases, leptospirosis is treatable with doxycycline. Low Phosphorus Beef {br} The leptospirosis vaccine is made by Nobivac MSD animal health, a subsidiary of Merck. There are two vaccines available, Nobivac Lepto 2 which covers two serovars and Nobivac Lepto 4, that covers four serovars. We must note that the L3 serovars is not found in the U.K., so one quarter of the vaccine is totally unnecessary. Vaccinating dose not prevent your dog from getting leptospirosis, it is only meant to lessen the severity of the illness. Interestingly a post vaccination survey done by Canine health concern, observed and analysed the history of over 3,800 dogs post vaccination, found that every single dog in the study with leptospirosis, contracted it within three months of the vaccination, which begs the question are we reducing the severity or actually making our dogs more susceptible to it!? Findings here In a 2007 study completed before the availability of the Lepto 4 vaccination, 1,241 healthy dogs, some of whom had been vaccinated and some had not, found that 24.9% of dogs had antibodies 1-6 different serovars. This shows these dogs had natural exposure to these serovars and had built some natural immunity to them. Findings here In cases of the vaccinated dogs, some showed antibodies up to 1,745 days after vaccination. Is this from the vaccination? If so, why are we annually vaccinating? If not, is this from natural exposure? If so, why is it necessary to vaccinate? In 2013, Christopher Ball from Liverpool university wrote his thesis on leptospirosis. This was funded by MSD the manufacturer of Nobivac leptospirosis vaccine. A questionnaire was sent out to 472 vet clinics all around the U.K.. They were asked how many cases of leptospirosis had been seen in the last 12 month’s. 89 clinic’s returned the the questionnaire, the majority reported no cases at all in the last twelve months, only 13 of the practises reported a case within the last twelve months, of which only 3 had been confirmed by laboratory test. None of the practises in the study reported suspecting or confirming two or more cases of leptospirosis in the previous 12 months to the study. With these figures, we need to ask ourselves how prevalent leptospirosis is in the U.K.? And does it really warrant the risks associated with the vaccine? Gut Guardian We may need to look to other means for evidence of adverse reactions, there has been a Facebook group set up called “Novibac Lepto 4 -our experiences” with 35,000 members and growing. Some of whom are professionals all sharing their experiences of this vaccine. There are some extremely harrowing and heartbreaking stories in the this Facebook group. The manufacturer’s of the vaccine and some professionals will say these stories are anecdotal, this may be so, but it reaches a point when ‘coincidence’ can’t be ignored when so many of the same stories are being shared. The World Small Animal Veterinary Association (WSAVA) say that leptospirosis is not a core vaccine and in 2013 Christopher Day said in his thesis due to the perceived low rates of infection in the U.K., the leptospirosis vaccine is not considered a core vaccine, yet recently the BSAVA (British Small Animal Veterinary Association) made it a core vaccination. We would like to know what research and data this is based off. Leptospirosis is a killed vaccine (not live) and therefore contains adjuvants such as mercury and aluminium hydroxide, to stimulate the immune response when the vaccine is administered. This may potentially make it more dangerous in terms of adverse immune events in some dogs. Adverse reactions can be instant or within 7 days of administration. Symptoms can be anything from, sickness, diarrhoea, welts and swelling at the injection site, swollen glands, hives to anaphylactic shock, seizures, auto immune responses and even death. Vaccinosis however, is a disease resulting from a vaccination. This can occur many weeks and even months after the vaccine has been administered, hence why it can be difficult to get a vet to acknowledge and report adverse reactions. Leptospirosis is a zooatonic infection which means we can contract it from other animals. Lepto is known as weils disease in humans and we are often led to believe (from our vets) that it’s very important to vaccinate our dogs due to the risk of leptospirosis to ourselves and our families. However, on the NHS website it say ‘it’s very rare” to contract leptospirosis from our pets. When we take into consideration the low number of cases of leptospirosis, in Christopher Days study, and the fact the NHS have said its very rare to contract it off our pets, this would defiantly go against the consideration of this vaccination for our dogs. Findings here Health and safety executive .gov.uk say there is are around 50 cases of weils (Lepto) disease in the U.K. per year, out of a population of 65 million people. Some of those cases are brought back from abroad, its treated with antibiotics and there is no
Whether you describe your dog as a drama queen or not, most dogs are incredibly good at hiding pain. This mechanism makes complete evolutionary sense. Showing pain, showed a weakness of which predators could take advantage of. Here at my Pet Nutritionist, when you book for a consultation, we ask certain questions to determine if undetected pain could be present, amongst other things. Whilst you may immediately consider the dog limping or struggling to get out of their bed, chances are by this point, the pain has moved past a threshold that they are unable to hide. Our best chance as owners is to notice the subtleties of pain in the canine and know when to seek further help. So let’s explore the mechanism of pain in a little more detail, signs to watch out for what we can do for our four-legged friends. What is pain? We’ve all stubbed our toe in the middle of the night or stood on a piece of lego. This is acute pain, the event, despite being painful, is in fact short lived. This can occur for our dogs too, when they run into a plant pot in the garden for example. But pain can become chronic and this is often what they hide. Chronic pain is more commonly associated with musculoskeletal issues in our dogs, in cases of dysplasia or arthritis. But it can also be associated with gut dysfunction and many other diseases in the body. The origin of all pain is inflammation. Irrespective of the type of pain whether it is acute or chronic pain, peripheral or central pain, nociceptive or neuropathic pain, the underlying origin is inflammation and the inflammatory response. So what is the inflammatory response? Inflammation is a normal response of the body to protect tissues from infection, injury or disease. The inflammatory response begins with the production and release of chemical agents by cells in the infected, injured or diseased tissue. These agents cause redness, swelling, pain, heat and loss of function. Inflamed tissues generate additional signals that recruit leukocytes to the site of inflammation. Leukocytes destroy any infective or injurious agent and remove cellular debris from damaged tissue. This inflammatory response usually promotes healing but, if uncontrolled, may become harmful. Acute inflammation typically lasts only a few days. If a wound gets hot, turns red, hurts, and swells, we recognise that inflammation is at work. In this instance, inflammation is a beneficial process, serving to immobilise the area of injury as the rest of the immune system mobilises to heal. The treatment of acute inflammation, the administration of non-steroidal anti-inflammatory agents, provides relief of pain and fever. In contrast, chronic inflammation lasts weeks, months or even indefinitely and causes tissue damage. In chronic inflammation, the inflammation becomes the problem rather than the solution to infection, injury or disease. Chronically inflamed tissues continue to generate signals that request help from leukocytes in the bloodstream. When leukocytes reach the tissue, they bring inflammation to the party. This chronic inflammatory response can break down healthy tissue in a misdirected attempt at repair and healing. As mentioned, perhaps the most understood cause of pain is joint inflammation. Repeated trauma or stress to the joint, incurred during everyday use, training, or performance, is often the cause of joint inflammation. You will notice the familiar symptoms like lameness, swelling and heat. The initial inflammation usually involves only the soft tissue structures of the joint, and cartilage damage is often not present at this stage. This inflammation allows leukocytes, or white blood cells, which are normally filtered out of the joint, to invade the joint space. The inflamed synovial membrane and the leukocytes release destructive enzymes such as free radicals, cytokines, and prostaglandins, all of which are potentially damaging to the cartilage. This is primarily what anti-inflammatory medications work on, they generally inhibit the production of prostaglandins. Joint degradation is an unfortunate side effect of ageing, but this can occur a lot sooner in those working or particularly active dogs. Degradation can also occur as aside effect in cases of dysplasia; as the bones are not sitting in the joint correctly, friction results in excessive degradation and subsequent inflammation and pain. In these cases, treatment is more relating to pain management and making your dog more comfortable. There are a number of practitioners that specialise in musculoskeletal concerns in the canine. Specialist Vets Chiropractors Vets Qualified in Acupuncture Canine Massage Therapists Hydrotherapists Physiotherapist Whilst there are breeds that are genetically predisposed to conditions like hip or elbow dysplasia, being mindful of appropriate nutrition during development along with appropriate exercise during growth is essential. Large breeds undergo a rapid stage of development and so essential nutrients to bone mineralization should be included in the diet; namely whole food sources of calcium and phosphorus along with vitamin D. Weight should also be monitored in the growing puppy. The bottom line? Count the nutrient dense, fresh food additions to your puppy’s diet, not the calories. As an aside, there is a lot of attention paid to the calcium: phosphorus ratio in the growing large breed. The note to make is that organic sources of both minerals are slowly and less efficiently absorbed; so, in fresh fed dogs this is less of a concern in terms of excess. Phosphorus found in meat products however is more efficiently absorbed than that found in plants. Findings here Gut Pain As humans, we are familiar with tummy aches, well, this can also biochemically occur in the dog as well. They just can’t tell us about it. As we have noted, pain is inflammation, and there are certainly plenty of things that can result in inflammation. Inflammation in the gut can be a result of things getting to places they shouldn’t really be, and so the immune response is summoned. Potentially harmful substances can find their way into the gut, but anything that is identified as non-self, kicks up the immune system. This can simply be a poorly digested protein. If
Whether you are a seasoned raw feeder, rather new to the journey, the Gordon Ramsey of the home-cooked dog food world, or simply want in to add some fresh food to your commercial pet food, here at My Pet Nutritionist, we have a few favourite fresh food additions. Try saying that on a Friday night! Anyway, they all pack a fair punch in terms of nutritional value, so we’ve decided to let you in on our secrets. 1) Green Leafy Vegetables! Top of the list for a reason. Green leafy vegetables include spinach, kale, watercress and broccoli. In green leafy vegetables you will find vitamins A, C, E and K along with many of the B-vitamins. These vegetables also contain carotenoids. Carotenoids act as an antioxidant, deactivating free-radicals and limiting the damage they can cause. There are two broad classifications of carotenoids: carotenes and xanthophylls. The latter containing oxygen, whilst the former do not. Xanthophylls include lutein and zeaxanthin, which are both primarily associated with eye health. They are often indicated in cases of macular degeneration. Beta-carotene one of the carotenes is turned into Vitamin A and is found in those green leafy veg like spinach and kale. Vitamin A is important in maintaining healthy skin, mucous membranes and supporting a functioning immune system. Vitamin A is regularly implicated in abnormal hair cycling, both deficiencies and toxicities can cause issues. For that reason, it is generally deemed that a whole food diet is more than capable of providing healthy levels. Green leafy vegetables also contain a rich source of folate, this is after all, where the name came from. Folate comes from the Latin folium, because it was first found in leaves! Folate functions as a coenzyme in many processes in the body. It is needed to make DNA and other genetic material and is essential in cell division. In short, it helps tissues grow and makes cells work. Folate is also involved in neurotransmitter synthesis, so it is implicated in mood and subsequently behaviour. And, one particular study showed a reduced rate of bladder cancer when leafy veg was added to the dog’s diet! Findings here So, lightly steam your kale or spinach, or blitz it up in a blender, pop it in a freezer mould and add them to your dog’s bowl! 2) Mushrooms! There are literally thousands of species of mushrooms on the planet, so it can be a challenge to know where to start. But they are incredible in terms of the benefits they can provide. Mushrooms can be involved in the prevention of certain disease, the regeneration of damaged cells, the protection of tissues and cells and used during treatment of existing conditions. The bioactive compounds of mushrooms include polysaccharides, proteins, fats, ash, glycosides, alkaloids, volatile oils, tocopherols, phenolics, flavonoids, carotenoids, folates, ascorbic acid enzymes, and organic acids. Reishi mushrooms are adored for their immunomodulating benefits. In short,they have regularly been used successfully in chronic autoimmunity and allergy cases. Maiitike mushrooms have been used for their antibacterial function and cordyceps have been seen to inhibit inflammatory responses throughout the body. Findings here Certain species have been seen to stimulate natural killer cell function, supporting the innate immune system in the body. Mushrooms are widely accepted a having anti-cancer properties. The bottom line? Mushrooms have been seen to be: Anti-inflammatory Anti-microbial Antioxidant Prebiotic Anti-diabetic If you are looking to add mushrooms to the bowl, cook them fully, lightly sauteed is fine. If you are looking to use them therapeutically, then please feel free to get in touch for advice and guidance. 3) Eggs! There’s a reason eggs are the protein reference. They contain the full essential amino acid profile. Eggs contain essential lipids, proteins, vitamins, minerals and trace elements including vitamin A, iron, vitamin B12, riboflavin, choline, zinc and calcium. Egg proteins are distributed equally between egg white and egg yolk, whilst lipids, vitamins and minerals are essentially concentrated in the egg yolk. The yolk is a rich source of linoleic acid and as we know, LA is abundant in the epidermis of the skin, so eggs are a great source of food to support skin health. The one thing that eggs are rarely associated with is being anti-microbial. But there are a range of proteins found in the egg that exhibit antibacterial, antiviral, anti-fungal and anti-parasitic activity. Avidin is seen to target bacteria, lysozymeis seen to target bacteria, virus and fungi, and cystatin targets the above with parasites included! Chicken eggs also contain a range of antioxidant compounds that include vitamins, carotenoids, minerals and trace elements. They have demonstrated reductions in pro-inflammatory cytokines in vitro. Conclusions suggest the supplementation of egg yolk proteins to reduce intestinal oxidative stress. Findings here Lysozyme, an enzyme found in eggs has been indicated in the treatment of inflammatory bowel disease; it has been seen to protect in cases of colitis. Largely from its anti-inflammatory properties. Findings here Where you source your eggs from is essential, free-range birds produce more nutrient dense eggs than caged. Free-rearing results in much higher levels of tocopherol, alpha-tocopherol and lutein content. The anti-microbial function of the egg white is also modulated when hens are exposed to environmental microbes. Findings here So, if you want to add egg to the bowl,source free-range and organic. You can feed raw or cooked, and the egg shell is perfectly safe to feed too! 4) Berries! If you’re in the middle of a yeast or gut healing protocol, then berries may not be the first thing to add to your bowl, but for the typical dog, they are a beautiful addition. Berries contain many vitamins but that also have an impressive antioxidant profile. Anthocyanins (Greek anthos =flower and kyáneos = blue) belong to the flavonoid group of polyphenols, which are responsible for the red and blue colour of plant organs such as fruits, flowers, and leaves. Many studies have linked these compounds with antioxidant, anti‐inflammatory and anti-carcinogenic properties, protection against both heart disease and cancer, as well as a
As we look at photos or videos of dogs devouring their food, when we are dealing with a fussy eater, the question we always sit with is; why won’t my dog do that? Being a fussy eater can be technically defined as an eating disorder, and there are a number of causes. From behavioural to biochemical, let’s take a look at the complex world of the fussy eater and we’ll share our top 5 tips for dealing with them. Eating Behaviour Appetite and hunger are largely controlled by the brain and a range of hormones. In the brain the hypothalamus receives information from the digestive system like stomach extension, chemical nature of ingested food and the metabolic activity of the liver and uses it to maintain energy balance. It also receives information from the emotion/reward system. Food is a rewarding object that induces pleasant emotions. Studies have demonstrated that when the reward value of food decreases, so too does eating motivation. Sadly, these studies often include the injection of lithium after eating, which causes discomfort, but it does give us food for thought, pun intended, if our dog is eating food which may be causing them discomfort. The most discussed hormones when we are looking at appetite and hunger are leptin and ghrelin. Leptin is produced in adipose cells, or fat cells. So, the more fat cells there are, the more leptin is produced. In short, the more fat that is available in reserves, the less you need to eat. Ghrelin is predominantly secreted in the stomach, and it too modulates cells found in the hypothalamus by increasing excitatory inputs and decreasing inhibitory inputs. Here we are talking about neurotransmitters. Ghrelin is seen to have a large influence on the release of dopamine via increases in cell excitability. As dopamine is involved in reward and motivation, ghrelin is thought to target the motivational functions geared to gaining food and to select those which are more rewarding (high calorie). However, there are also other mechanisms in which the dopaminergic system comes into play for the fussy eater. A central feature of the dopamine neuron response is that it is triggered by unexpectancy. After receiving an unexpected reward like food (or how many likes our recent post has got on social media) a dopamine surge is elicited. For the dog who ends up with the same bowl of food every day, there is no longer unexpectancy. The other neurotransmitter that gets a little attention in terms of eating behaviour is serotonin. Serotonin has a well confirmed role in the regulation of eating behaviour. Serotonin is a key player in feelings of nausea – so higher levels could be produced in response to something not sitting quite right in the digestive system. What’s super interesting is that serotonin is metabolised largely by monoamine oxidase (MAO) so it stands to reason that MAO inhibitors can contribute to high levels in the body. Sadly, certain insecticides found on flea and tick collars contain MAO inhibitors. We must also consider the cascade of hormones that are released during the stress response. Stress is a redirection of resources, and this includes away from digestive function. If our dogs are exposed to acute or chronic stress, it could remove their desire to eat. That said, as an owner managing a fussy eater, the owner too can become stressed and anxious that the dog isn’t getting the nutrients they need to thrive. Unfortunately for us, dogs have incredible olfactory capabilities, meaning they can smell our stress! They also have this capacity to mirror our emotions. And so, when they don’t eat, we get stressed, so they get stressed and may be even less likely to eat. So what does all of this mean? If you have investigated further and there is no underlying health issue that could be causing your dog to be a fussy eater, they could: Be suffering discomfort from the food they are eating, whether this is a sensitivity, or issues with digestion. They are then less likely to want to eat it next time for fear of feeling poorly. Have an undesirable body score – there is a difference between the occasional fussy eater, and the chronic fussy eater. If your dog is only occasionally refusing food, they may well just not need it at that moment. Be bored with their food – this often applies to many commercial foods – dry food we’re looking at you. Having the same bowl of food every mealtime removes the sense of unexpectancy. Be stressed or sense our stress – have there been any recent changes to your routine? Are you more stressed than usual? Has their walking route changed? Have they had an altercation with another dog on a walk? Are there any new pets in the home? Have you moved any furniture? Have you noticed any other changes to your dog’s behaviour? Have there been any changes to your behaviour? Our 5 Top Tips for Managing a Fussy Eater: 1) Establish mealtimes! There’s no unexpected reward if a bowl of food is always laid out. 2) Ditch the dry! What is more boring than the same bowl of pellets every mealtime? Offer fresh food with a range of tastes, aromas, and textures. In addition, variety is the spice of life – use novel proteins – what’s more unexpected than novelty? This can also be helpful if you are concerned your dog may have a sensitivity to certain foods. Finally, cooking alters the aroma and texture of many foods so this can be a great way to entice if needed. 3) Use mealtimes as opportunities to enrich your dog’s life! Offer food in bowls or plates, or even on wooden boards. There is no categoric link between height of feeding and gastric torsion in dogs, so consider at what level you offer their meals; do they need to be raised if they are struggling with any musculoskeletal issues. If they are in pain whilst eating,
Gone are the days when you could walk into a pet shop and have the choice of three types of food: the cheapest, middle of the road and the most expensive. Thank goodness! But we now have a new problem. What on earth do I feed my pet? Do I feed dry kibble? Quite simply, NO. But what about the rest? Canned? Dehydrated? Commercial Cooked? Home Cooked? Commercial Raw or DIY Raw? At My Pet Nutritionist, we can help guide you. In an age of choice, is there a “best diet”? Obviously human research demonstrates fresh feeding over processed foods is far healthier for us and can prevent disease. this applies to our pets too however our job is to look at the pet, holistically and consider all constraints involved. Whilst we know there are rules of thumb for optimal health, much like for us humans, all pets are different. There may be a perfect diet for your pet, but that same diet may not be perfect for your neighbour’s pet. So let’s explore the different foods available to you, what we like about them and what considerations need to be made, if in fact they are your foods of choice. Raw Feeding Raw feeding is just that, when you feed meat, fat, bones etc in their raw state. Within raw feeding there are a number of approaches. You may come across phrases like BARF which stands for biologically appropriate raw feeding, or RMB which stands for raw meaty bones, you may also come across PMR which is prey model raw and more will no doubt appear over the coming years. The basis of a raw diet comes from considering the evolution of the dog. Dogs came from wolves, and before domesticated by humans, would largely fend for themselves; eating whole prey; eyes, brains, guts galore (although there is some data that suggests the guts were often left, which leads to the suggestion that dogs avoid greens when given the opportunity, but this isn’t always the case and some leafy greens pack some punch in terms of nutritional value). The biggest concern around raw feeding is contamination and so, we must practice appropriate handling techniques when handling any raw meat, just read the packaging on your raw chicken fillets. The more recent development is around antimicrobial resistance. Whilst raw food poses a risk, so does the inappropriate use of antibiotics, excessive use of disinfectants and sanitisers, livestock rearing techniques and pesticide use along with many more. Within raw feeding you may come across the 80-10-10 method. This is where you feed 80% meat, 10% bone and 10% offal (organs). This is what most commercial raw food manufacturers offer, in a ground state, as a basis for their meals. But you can also formulate a raw diet to FEDIAF guidelines, again some raw food manufacturers provide products that meet these requirements and offer complete foods. Raw food is in its original state, apart from being processed through a meat grinder in pre-made minces, what you see is what you get. Feeding a raw diet has been associated with a range of improvements and health benefits in pets: Digestibility of crude protein and fat is improved in raw foods compared to dry practical pet foods. Dogs fed a RMB diet have a significantly more diverse microbiome than commercially dry fed dogs. Dogs being fed a RMB diet demonstrated a high digestibility of nutrients. Generally, the size of stool is deemed as a measure of digestibility in pet food manufacturing and in raw fed dogs, stool size significantly diminishes (suggesting improved digestibility). Dogs fed dry kibble compared with a raw food diet have demonstrated altered immune cell gene expression. Keto diets have been seen to improve outcomes in pets with cancer; a raw diet is largely based on keto principles. In a randomised clinical trial in 2012, the positive effect of a raw diet was reported in relation to the formation of calcium oxalate uroliths. Lower calcium excretion was found in the urine of dogs eating a commercial RMBD, compared with excretion in dogs eating a commercial dry extruded diet. An initial analysis of the Dog Risk data (Helsinki University), has revealed a decrease in the incidence of atopy and allergy in dogs that eat RMBDs. It appears that an RMBD fed at a young age has a positive influence on reducing the incidence of atopy in the population. Eating raw meat, raw bone and cartilage gave the strongest association of any the food items consumed in the study. Results have indicated that raw food, fed at a young age, could protect German shepherd dogs from CHD (Canine Hip Dysplasia). All findings here Dogs fed raw food often have less plaque build up and white teeth on raw food. Pets have a dietary requirement for protein and fat. Protein to build and repair cells, fat to provide energy, insulation and to act as signalling molecules. They also have a requirement for a range of micronutrients, those vitamins, and minerals. Meat, bones and offal are full of available nutrients, in their original state. Raw is perfectly able to provide nutrients for your dog to thrive, but the dietary plan may take some tweaking to get it right. Some dogs take to bone straightaway, some need a little longer. Some can tolerate 10% offal, some start to get black, tarry poops without an offal free meal or day. The Poop Gives you the Scoop As much as we’d like to tell you the eyes are the window into the soul; when you’re feeding a pet, if you want to know what’s going on inside, keep a watchful eye on their poop. Too much bone in a raw food diet starts to give white, crumbly poop. Too much offal is usually a black and tarry poop. There are other indicators too, but here at My Pet Nutritionist, we’re not averse to a poop pic, so if you are worried about your dog then please feel free
If you’ve just rinsed your dog off after a meander through the woods, then their licking is likely grooming behaviour. But, here at My Pet Nutritionist, we often see dogs who excessively lick causing abrasions and hair loss. Whilst it’s often indicative of an irritation, there are in fact some other reasons why your dog may start licking in the absence of a jaunt through a muddy puddle. Let’s take a look at some of the more common causes. 1) Stress Yes – stress can take the blame for this one too! Stress is like the wonder woman of life – is there anything she can’t do? For anyone who has spent time investigating dog behaviour, you’ll know that lip licking in particular is a sign of stress. An interesting theory here suggests that because stress depletes essential nutrient resources, lip licking is in fact a sign of malnutrition. Deficiencies in a range of nutrients like vitamin B2, B3, B12, iron, and Vitamins A, C and K and Zinc have all been known to cause irritation and inflammation in and around the mouth and lips. The licking is thought to be an attempt to soothe it. Findings here However, other suggestions explore the idea that the lip licking mechanism is thought to soothe the stress response by activating the parasympathetic nervous system. Yet, this mechanism can apply to licking of all body parts, not just the lips. The stress response is dominated by the sympathetic nervous system; it increases heart rate, widens eyes in order to assess the threat better and redirects resources in order to deal with it. Once the threat has passed, the parasympathetic nervous system kicks in and re-balances. The chief of the parasympathetic nervous system is the vagus nerve, and chewing, along with licking is considered to activate it. Through the action, attention is redirected and focussed on that particular task, not what is making them stressed. Findings here Licking is also deemed a self-soothing behaviour through its association with oxytocin. Oxytocin is a hypothalamic nonapeptide linked to increased levels of social interaction, well-being and anti-stress effects. Oxytocin is released by sensory stimulation (touch) and promotes the release of dopamine whilst decreasing the cascade of stress response mechanisms throughout the brain and body. Oxytocin also modulates the activity of serotonin which as we know is a key hormone in mood stability, feelings of well-being and reward. An element of this could have also been learned behaviour from their mother. Licking and grooming behaviour is a key feature in determining neural changes and fear responses in offspring. Those from low licking mothers tend to show a greater stress-response and proceeded to be low-lickers themselves (if they were female and had their own litter). The same also occurred for high lickers. Findings here The bottom line? Excessive licking could be a response to stress faced by your dog. Watch out for other signs of stress like: Panting in the absence of exercise Salivating in the absence of food Pacing Inappropriate toiletting Unusual vocalising Out of character behaviour Wide eyes Flat ears Abnormal tail placement Work to remove the trigger and support them with other stress reduction strategies. Also, be mindful that chronic stress can deplete essential nutrient resources. our Calm Complex can help support the above signs of stress. 2) Pain Pain is an uncomfortable feeling that gives us and our dogs an indication that something isn’t as it should. Not only are many breeds incredible at hiding pain (it wouldn’t have helped them in evolutionary terms), but they also lack the ability to converse. Whilst we would all love to think we have this form of communication with our dogs, we can miss things, especially if they are pretty crafty at hiding them! The sensation of pain is a necessary function that warns the body of potential or actual injury. Whilst we may think that dull ache in our lower backs is merely an inconvenience, it’s a rather reliable indication that our office chair possibly doesn’t suit us. Pain occurs when a nociceptor fibre detects a painful stimulus on the skin or in an internal organ. This detection is picked up by other receptors in the spinal cord and brainstem and then transmitted to the various areas of the brain. This is done through the incredible work of neurotransmitters. There exists both inhibitory and excitatory neurotransmitters. Those that make things happen, and those that apply the brakes. Inhibitory neurotransmitters are involved in the modulation of pain; including enkephalins and endorphins, serotonin, noradrenalin, GABA, acetylcholine and oxytocin. Excitatory neurotransmitters acting without an inhibiting system results in pain. Which is why pain killers primarily prevent the release of some excitatory neurotransmitters (and can in fact make you or your dog drowsy). When we look at the neurotransmitters involved, it’s possible to see why our dogs may start licking an area that is painful to them. Through touch they can stimulate the release of oxytocin (a modulator of pain). Not only that but self-trauma (excessive licking) is thought to promote the release of endorphins, which are also pain modulators. Findings here This demonstrates how dogs can get into a vicious cycle, they want to lick to soothe, but the more they lick, the more trauma they cause, resulting in more licking. There is also the possibility, that what could have started as a pain response, could turn into irritation, or what started as irritation, could turn into pain and continue the cycle. 3) Itch Itch is a sensation felt on the skin, which causes the desire to scratch. Although initially it could be as simply as scratching something to remove it, itching can become stressful when excessive. When tissues are stimulated by allergens, histamine is released from mast cells. Histamine makes the blood vessels expand, driving blood to the area creating that common swelling among other responses. Specialised nerve fibres are stimulated; when these are processed, the scratching or rubbing reflex is stimulated. The main mediators for the itch
Help! My dog has a loose stool! Well, you wouldn’t be a true dog owner if you didn’t spend time assessing, talking or even sharing photos about your dog’s bowel movements. Here at My Pet Nutritionist, we’re not averse to a poop pic (we get quite a few in a day), but there are some common reasons why your dog may develop high scores on the Bristol Stool Chart. Technically that’s a chart for humans, but we can learn similar lessons. Here is our Ultimate Dog Stool Guide on colour and consistency. So, let us take a look at some of causes of runny poops in dogs. 1) Infection It goes without saying that a nasty gastro bug can result in runny stools. It can be all sorts of different colours, but more often that not it can be described as like turning a tap on! Infections can be a result of bacteria, parasites or virus and you may notice other symptoms like lethargy, vomiting or abdominal pain. In some cases, due to the irritation in the gastrointestinal tract, you may find specks of blood in the stool too. If nothing sinister, a fast followed by a bland diet will start to show improvements, but if there are other clinical signs or no improvements then its always best to get your dog checked out by your Vet. A vet call is always warranted for young puppies or elderly dogs. 2) Gut Dysbiosis Stool consistency strongly correlates with all known major microbiome markers. What this means is good poops are a sign of a healthy gut. But you knew that! Gut dysbiosis is when there is an imbalance between the good and bad bugs found in the gut. This can be for a number of reasons: Antibiotic use Steroid use Diet diversity Environment – exposure to toxins Birth method Use of flea and wormer treatments Vaccination When we are looking to heal the gut, we follow the 4 R’s. Remove (food antigens that could cause reactivity) Repair (the gut lining/endothelial, possibly known as leaky gut) Restore (the good bacteria in the gut) Replenish (with enzymes if necessary to reduce immediate inflammation) Signs of gut dysbiosis will usually manifest as regular sub-optimal bowel movements, if you think they may be an issue faced by your pet, we are more than happy to help! 3) Food Sensitivities/Allergies Allergies are in fact incredibly rare (at around 10%), but sensitivities are one of the most common issues discussed here at My Pet Nutritionist. An allergy is the result of an over-zealous immune system. It’s like going for the theory part of your driver’s test when you are told you are limited with how many clicks you can make on your hazard perception. Well, in cases of an allergy, the immune system didn’t get the limited clicks memo and gets a little trigger happy! The basic function of the immune system is to get rid of potential threats; it can do this by engulfing parasites, and you guessed it, causing a swift exit in the form of diarrhoea. But diarrhoea is also a sign of a food intolerance. Rather than an immune response per se, an intolerance involves the digestive system; in short, it struggles to process a particular food. This can be due to a lack of enzymes to digest a particular food, a sensitivity to chemicals found in certain foods or health issues like irritable bowel syndrome (which is often linked to bacterial overgrowth, stress, post-infection and genetics). In cases of food sensitivities, an elimination diet is the first port of call, to establish the key offender and we again follow the 4R’s in gut healing. 4) Stress Our pet’s stress response is much like ours as a human. Eustress or good stress can improve alertness and motivation and provide a helping hand in performance. But distress is the one we need to worry about, especially if it becomes chronic. Stress is generally known as the fight or flight response. The cascade of changes occurring in the body redistribute resources; blood is directed to the brain and limbs to figure out what to do, and whether to run away or stand and fight. Despite us making evolutionary progress, neither us or our dogs have yet evolved past this response and so even potentially minute stressors result in this redistribution of resources; taking ours and our dog’s ability to effectively digest food with it. Digestive function returns when the parasympathetic system kicks back in; once the stressor has passed (but incases of chronic stress, this doesn’t occur). In times of chronic stress, food is ingested, but not digested properly. This also explains why you may notice your dog has “adrenaline” poops on walks, or when they get particularly excited. As they are doing their zoomies, the body interprets it as stress and so directs resources where they are needed (not to the effective digestion of food). This is short lived and the dog’s next poop that evening has usually returned to its normal presentation but, under long term stress, this lack of digestion demonstrated by recurring loose stools, can result in a range of health issues thanks to the malabsorption of nutrients. If you consider your dog’s loose stools are generally associated with certain stressful events, the key is to remove the trigger where possible. Counter conditioning is often successful in supporting their future stress-responses. Stress does deplete essential nutrients, so opting for a fresh-food diet with excellent bioavailability is vital in supporting your dog during these times. 5) Underlying Malfunction Loose stools are the result of food being passed through the colon too quickly; with less fluid being absorbed by the body, the result being that puddle in your garden. As we mentioned earlier, a lack of digestive enzymes can be a reason for this. The digestive system comprises the GI tract, pancreas, liver, and gallbladder. If there is an underlying malfunction in any of these, you may find abnormal stools. The pancreas
When we talk about toxins at My Pet Nutritionist, we are talking about flea and tick treatments, worming and even households chemicals. The extra sprays of air-freshener, the over-powering smell of disinfectants and most things in the home being wiped with fabric softener. In a pet-free home, as a grown adult, it’s entirely your choice what you expose yourself to and if you want your home smelling like that, then go for it! But when you make the decision to care for a pet, who can’t tell you when they are feeling nauseous or have a headache, you have to think a little more carefully. How many of you go to a friend’s home and notice the sweet smell of their air freshener or carpet cleaner? But when you get home, you can’t smell your own? This is because we develop a tolerance – our homes may not smell strongly to us, but they may to our pets. Especially our dogs. Dogs possess an extremely strong sense of smell. Which is why they have found themselves with some of the most impressive jobs in the world; some become medical detection dogs as they can detect minute changes in a person’s odour, signalling disease. It is believed that a dog’s sense of smell is 10,000-100,000 times that of an average human. They could detect the equivalent of one drop of liquid in 20 Olympic sized swimming pools! Findings here So, even if we can’t detect a compound in our environment, it’s safe to say, our dog probably could. Your dog is detecting volatile organic compounds (VOCs). Now, they detect these in cancer sweeps (different cancers will produce different VOCs), but most of us know of VOCs for the bad rap they have. VOCs are chemicals that evaporate under normal atmospheric conditions (room temperature, low boiling point), compromising air quality. It’s fairly obvious when you spill some fuel at the garage, or you’ve recently painted your kitchen. The odour is compounds in the air, that you breathe in and subsequently stimulate/inhibit your olfactory receptors. Findings here VOCs are found everywhere. They are released by many everyday items including: Cleaning Products – detergents, bleaches etc Air Fresheners Paints Deodorants/Perfumes Fabrics Rugs Vinyl flooring Wood Burners Cigarette Smoking Printers and photocopiers This list is not exhaustive but covers the main culprits in most homes. But why are they a problem? Many VOCs have been proved as carcinogenic. That is, they are known to cause cancer. This largely depends on length of exposure, but it is still a risk. Findings here Many studies are showing the moderate to strong increase in respiratory distress or allergic effects of exposure to VOCs. As you would expect, irritation of the eyes, nose and throat is regularly reported. It stands to reason there would be an increase in allergies reported when exposed to certain VOCs. How bad is it? The health effects of a certain VOC will depend on its chemical nature and also the degree of exposure. Exposure can include ingestion, respiration and absorption through the skin. Here, we wondered whether a long-coated dog, or cat is any worse off? If the compounds stick to their coat? They are carrying the compound around with them. But we have not yet found any data to explore this query. Consider that your pet will spend a good 20-23 hours a day in your home, accounting for a 1-2-hour walk or a prowl at night time. Obviously less if they attend day care or come to work with you. But that is a high level of exposure – you are likely out of the home for a much larger part of the day. Whether you work 8-10 hours, or you are part time and then nip to run errands. In humans, it is clear that VOCs disrupt hormones and reproduction which subsequently affects the development of babies and children – it’s not a push to suggest this could happen with our pets, so it’s advised to be even more mindful with pregnant bitches, litters of puppies and when you bring your new puppy home! Findings here In an age where we want our homes grey and white and smelling of spring flowers all year round, we are inadvertently exposing our pets to some pretty harmful compounds. So, what can we do about it It’s not as hard as you’d think. Firstly, if you are re-decorating, try to do so at times of the year where you can have windows and doors open to bring fresh air through the home. Also, opt for water-based paints as these contain much lower level of VOCs. If you are unsure, speak to your local DIY or paint supplier and ask for a low content specifically. Store partly used paints and solvents in the garage or shed, where people and pets are unlikely to spend much time. If you know you won’t ever use it again, offer it to friends or family to use or simply dispose of. When cleaning, check the labels of the products you use for common harmful VOCs including: Acetone Butanal Carbon Disulfide Dichlorobenzene Ethanol Formaldehyde Terpenes Toluene Alternatively, opt for environmentally friendly products. There are so many new companies popping up who use natural ingredients to help keep your home in tiptop condition. Most are also conscious of plastic usage. We recommend products from Iron, Method, Ecover and Velvet, you dissolve a sachet of product in water in a bottle that you are reusing. The ingredients are plant-derived and essential oils are used for fragrance where possible. They smell great. White vinegar is a great product to have in the home, it’s a powerful odour neutraliser. Perfect if you are toilet training or are worried that your home smells of wet dog! Activated charcoal is also a great odour neutraliser and air purifier. Pop bags around your home, in your car etc and you’ll soon notice odours disappear. Some gift companies have even started making bouquet style bags, specifically for this purpose! Citrus
Here at My Pet Nutritionist, we often see rest and recovery as a forgotten need of dogs. With the advent of daycare centres and dog walkers, most of us relish the idea that our dog can be kept occupied whilst we are in work. When owners research potential breeds to bring home, their exercise quota is usually discussed along with the need for mental stimulation. Exercise is important for canine health – we’ll come back to that later. So is mental stimulation, especially for those smart, working breeds. But there needs to be a balance so lets discuss, why we let sleeping dogs lie. Pop into any social media group discussing dogs being left alone and destruction inevitably comes up. Well-meaning owners often suggest that the dog is bored and by providing things for the dog to do, they will cease the destructive behaviour. It’s clear that destruction when left alone is a symptom of anxiety; not boredom. Toys and food are only ever used in a separation anxiety protocol to help the dog make positive associations with a confinement area. Part of this protocol is to assess how the dog behaves immediately after finishing the puzzle to establish whether in fact it was a distraction or actually taught the dog to relax. Boredom in dogs often isn’t the big deal that social media groups make it out to be. Those behaviours associated with boredom are often symptomatic of frustration or anxiety. So, how much interaction does your dog need on a daily basis? This is a difficult question to answer. As with humans, dogs have different personalities and purposes. However, we can’t argue with the science. Dogs are diurnal. Like us, they are active during daylight hours. Rest occurs during the dark. But activity increases in the last two dark hours. A rest period is common at noon and then reduced activity continues during the afternoon. Findings here Sleep is widely studied, for its evolutionary benefits. It is crucial for most daily functions. It is clear in humans, that when suffering sleep restriction, they have attention lapses, slowed working memory, reduced cognition and depressed thought. Studies have shown a significant reduction inactivity in dogs experiencing sleep restriction. Findings here One of the main purposes of sleep is to consolidate memories or learning. This has also been found true in dogs. Learning affects sleep structure which ultimately decides whether you retain the information or not. Interestingly, in studies, those dogs allowed to sleep after learning anew command were more likely to retain the command at a later date than dogs allowed to walk or play. Findings here So, if you want to train your dog, they need their sleep. Under laboratory conditions, dogs will sleep around 13 hours per day. But this is very generic. Older dogs will sleep more as they tend to experience periods of broken sleep. Puppies too will sleep a lot more – generally 18-20 hours. The rule of thumb is to let sleeping puppies sleep! For the puppy, consider how much socialisation and training you are undertaking. When you think you’ve only got around 4-6 hours per day of awake time; take some mealtimes out of that, and your safe play in the garden… it’s easy to see how you can quickly overwhelm a puppy. What’s really interesting is, like in humans, negative or positive interactions, affect sleep length and quality. Following a negative interaction with a human, dogs tend to fall asleep quicker. This goes against what we’ve found in humans; the idea that stress impedes sleep. It is termed stress-induced quiescence (protective sleep in response to stress). Findings here This throws a bit of a curve ball when we are considering the overall health of our dog. We usually understand that they are content when they fall asleep – but now we must consider that it could be a potential stress-response. It’s worth looking out for these patterns and seeing how your dog sleeps. This has never been more relevant when considering daycare. More and more are popping up and I often hear owners say that their dog does nothing but sleep when they get home. It is generally understood that the dog has had such a busy day, they are just exhausted. But, what if, in these daycares with upwards of 50 dogs on site, the dog is just over-aroused? How realistic is it for your dog to get his rest in such a busy site? When his normal rhythm tells him to rest around noon and then have a quiet afternoon, and he’s actually running, chasing and playing for 8-10 hours of the day? This is sadly where non-aggressive dogs get labelled as aggressive, simply because they have reached their peak of “activity” for that day and some annoying puppy continues to hang off their ear! Also a consideration to be made when a new puppy is introduced into an adult dog home. Any daycare worth their salt should value rest and recovery as much as play and interaction. Sleep is not the only way that your dog can rest and recover. Simply having quiet, settled time can be of benefit. All too often, owners consider that their dog always needs to be doing something. Here it must be questioned, does your dog need to be kept occupied simply to keep them out of trouble? Some dogs just don’t learn how they need to behave because they aren’t given the opportunity. This is a whole new issue which is too big to tackle in this article. Maybe at a later date. If your dog has their own space, whether it’s their bed, a crate, a den or a corner in the home, they soon learn that it is their safe place. They can learn to settle and rest there. But they need to know that no one will hassle them, so children need to keep their distance. You can use lickimats or stuffed kongs to help them associate the space with calm and quiet,
