Speak to any dog owner who has had the pleasure of those puppy years and you will hear about how that lapse in attention resulted in a chewed leg chair or a demolished sandal. Owners will say, “they’re just teething!” or “It’s just how they make sense of the world!” Is this true? We wanted to explore why puppies bite, nip and mouth and share some top tips on how to stop them. So, why do puppies bite? If you pay close attention to puppies playing, they use their mouths. All the time. There is a good reason for this, but to understand fully, we must look at their teeth in a little more detail. Puppy Teeth 101 Puppies are born without teeth. At 2-3 weeks old, a puppy’s milk teeth will start to come through. These will be the incisors. Puppies should have a total of 12 incisors, 6 on the top and 6 on the bottom of the mouth. 4 weeks will see the development of their 4 canine teeth. These are those sharp long teeth. At any time between 3 and 6 weeks old, you should see them develop their pre-molars. By the time they reach 8 weeks old, your puppy should have a complete set of milk teeth. 28 in total. 12 incisors 4 canines 12 pre-molars 14 in the upper jaw and 14 in the lower jaw. That’s a lot of teeth for a small puppy! And so sharp! Why are puppy’s teeth so sharp? There are two reasons for this. Anyone who has been nipped by a puppy will remember those pin prick teeth. Consider the nursing Mother. When those first sharp teeth start coming through, they will start to irritate the Mother making her reluctant to nurse and want to move away from her puppies, leaving them to search for alternative food sources. This is when the weaning phase starts. Those sharp teeth are the first step for those puppies becoming independent. They learn that they need to seek out other food sources. Their survival depends on it. Sharp teeth don’t only irritate their Mother, they also annoy their siblings. Which leads us into the other reason puppies bite and why you will constantly see puppies using their mouths whilst playing. Puppy biting aids the learning of bite inhibition. It is crucial that puppies learn bite inhibition, this is where they learn to limit the force and strength of their bite. It teaches them that other dogs and humans are fragile. A dog has one defence and that is to bite. Every dog is capable of biting out of fear and anxiety, bite inhibition is a vital technique to limit the damage a dog can do. When puppies are playing together; chewing and nipping, if they bite just a little too hard, those sharp teeth will hurt their sibling. You will often hear a loud squeal or yelp. This tells the offending puppy that it was a little too hard. Play after this interaction will usually stop, so by trial and error, puppies learn that when they bite hard, play stops (the good thing goes away). So if they want the good thing to continue, it’s in their interest to not hurt their sibling. Findings Here So those sharp teeth kick start the weaning phase through their Mother’s reluctance to nurse and they also aid the learning of social etiquette. The reason this learning starts so young can be explained through their further development. Specifically of their jaw formation and also growing their adult teeth. From 8-12 weeks onwards, your puppy should start losing their puppy teeth. This is due to the adult teeth forming and pushing the milk teeth out. You may find some around the house, but most puppies tend to swallow them. This can be a pretty painful time for your puppy, so offering puppy safe things to chew and soothe is super important. Frozen carrots or cucumber are great soothers! This is a good time to double check the adult teeth are forming properly and also to check they have a normal bite. The normal bite of a dog is termed a “scissor bite.” This is because the upper incisors sit in front of the lower incisors when the mouth is closed. However, it is common for short muzzled dogs to have a reverse scissor bite where the lower incisors sit in front of the upper incisors. Most of their teeth will have fallen out by the time they are 6-8 months old and they should have a mouth full of adult teeth. 42 teeth in total. 12 incisors 4 canines 16 pre-molars 10 molars You will notice that the molars are new. Puppies don’t need molars, but adult dogs do. Incisors are needed to rip meat and scrape it off bones. Canines are for puncturing prey. The molars are for grinding and crushing. With the extra teeth and the addition of those for grinding and crushing, it is possible to see why bite inhibition in puppies is so vital. No one wants to be bitten by any of those teeth! It’s not just the teeth that we should be worried about, it is also the strength of the jaw. Thankfully, puppies have weak jaws. They haven’t developed fully. Jaw-adductor muscles generate the main biting force in dogs. As puppies grow, these muscles get stronger. Bite force therefore increases. Findings Here So we can see why learning bite inhibition at an early stage is important. Dogs who learn how to use their mouth gently are less likely to bite hard or break skin if they do ever bite a person out of fear or anxiety. But outside of mother and sibling interactions, how do we teach bite inhibition? If your puppy nips or mouths at you during play, withdraw attention. Turn away from them. Remember that trial and error, when I bite hard, the good thing goes away? Whilst your puppy is playing appropriately, let play continue. You
There is a common misconception in the feline world. Many of us will see a hiding cat and make it our mission to coax them out. Whether this is whilst visiting a friend or taking in a new addition and they shoot straight under the cooker. We want them to come out so we can scratch under their chin. We want to reassure them. But what if we were to tell you that the welfare of said cats is greatly improved when they are given the opportunity to hide? Our want to reassure the cat is largely misplaced. We like to think we can fix it; but sometimes giving these cats the opportunity to decompress will fix more than our head poking under the bed with a handful of cooked food! To support the stressed cat we need to think outside of the box, or inside, as this case may be. Stress in Cats Cats get stressed. There is no denying that. But they are often a little more subtle in their anxieties than other animals. As in humans, cats will have the same response to stress. They may choose to fight, flight, or freeze. When they fight, they become aggressive and defensive. Flight will see them withdrawing from the threat and perhaps running away. When cats freeze, they crouch, lie still, and try to avoid any attention. At this point, you are probably imagining an outdoor cat with a territory to protect or one who has run into some difficulty on their hunt. But cats can become stressed for many reasons. They may spot an intruder (from the comfort of their windowsill), furniture may have moved, their litter may be different because the pet shop ran out of their usual one or there may be guests in the home and suddenly the day to day routine has drastically changed. You then have the colossal life changing events like bringing another new pet into their home, or them being the new addition to a busy home. The personality of the cat will largely determine how they respond to stress, much like in humans. Friendly and bold cats will often be more resilient in the face of change or stress; these are the cats who have generally experienced positive early socialisation, exposure to novel experiences and regular human handling. Interestingly, those cats who have a friendly father tend to grow up experiencing less distress in novel situations. Findings Here But it also seems that the personality of the owner can affect how a cat responds to stressful situations. If we explore the Big Five Inventory for human personality, owners who score high on neuroticism (who are more likely to feel anxious, worry and fear) report that their cats are more aggressive, anxious, and fearful. Owners who score high on conscientiousness report their cats are less anxious, fearful, aggressive, aloof, and avoidant. Those who are conscientious are often defined as organised and we know that a consistent routine is a great way to reduce stress-related behaviour in cats. Findings Here Studies like this include largely self-reported data, so the behaviour of both owner and cat could merely be perception, but it gives food for thought most certainly. Spotting Stress in Cats Cats can be incredible at hiding their emotions. This would have been an evolutionary advantage – no-one can prey on a weakness if they can’t see it. But there are subtle behaviours which show us they aren’t particularly fond of a situation. Immobility (freeze response) Crouched body Laying flat on their belly Tail under their body Wide eyes Flat ears Meowing, yowling, growling Hissing Shaking Excessive salivating Involuntary toileting Some cats will attempt to make themselves look bigger by way of piloerection. Their hand stands on end along their back, but more commonly you’ll notice a suddenly bushy tail. In dogs we notice this as getting their “hackles” up. This is an involuntary nervous system response because of the circulating adrenaline which makes the muscles contract. Be mindful though, cats will also do this if they are cold or aroused, so assess the situation to establish if it’s stress related or not. Again, this makes total evolutionary sense; a predator would think twice about hunting a larger prey. There is a ladder of response in most animals, and this is no different in cats. They will often show subtle signs of discomfort or stress. If the trigger doesn’t disappear, behaviour will progress. You may first notice flat ears, then the pupils will dilate. You may have a low growl or a silent hiss. Them running off or lashing out with their teeth and claws may be a few steps up the ladder. Chronic Stress For some cats, there are triggers which they can’t easily escape from. The most common is a multi-pet home. It is well-established that those cats exposed to dogs report higher stress-hormone levels in their urine. However, some cats have incredible relationships with resident dogs. Generally, if the cat is the first to arrive in the home, the cat-dog relationship will be more comfortable, and indoor cats are more likely to live amicably with dogs, than outdoor cats. Interestingly, it is usually the cat that is the driver of any aggressive encounters with dogs. In short, the cat will call the shots on whether the relationship is harmonious or not. Findings Here In a multi-cat home, it is much the same. Some cats cohabit perfectly well, but others may not. Strained relationships can result in excessive grooming, indoor soiling, spraying and even urinary retention, commonly resulting in conditions like cystitis. Cats may also self-soothe by way of sleeping and eating, so they may start to gain unnecessary weight. This is where the idea of learned helplessness appears. This is the “why bother?” concept of managing stressful situations. After repeated exposure to a stressor, the animal perceives they are unable to control or change it, so they stop trying. It’s easy to spot the acute stress
We are often told that the best time to learn a new language is when we are young and on the other side of the scale, that we will naturally lose some cognitive ability as we age. These concepts are true, but they also imply that we reach a plateau of learning or functioning, and we then must just wait for it to disappear. For the owner of an ageing dog, this is often a worry. The million-dollar question on many dog owner’s tongue – can we influence cognitive function as our pet ages, or do we just have to wait for it to “disappear?” It seems there is in fact some hope in the form of this concept known as neurogenesis. What is Neurogenesis? Neurogenesis is the process by which neurons are formed in the brain. Neurons are the fundamental units of the brain and nervous system; they transit information around the body, to other nerve cells, to muscles and even gland cells! Most neurons have a cell body, an axon, and dendrites. In a nutshell, they are crucial to coordinate all the necessary functions of life. Neurogenesis was thought to only occur in young, developing organisms like babies or puppies. But data is now suggesting that it can in fact continue throughout adult life and even into those senior years. Why is this important? Loss of neurons was thought to be irreversible – and the inability to generate replacement cells, quite simply affects functions necessary for life. For decades we saw how neuronal loss was implicated in neurological disease. One of the particularly interesting parts of the brain to be affected is the hippocampus. The hippocampus forms part of the emotional control centre known as the limbic system. It is so named due to its shape – it resembles a seahorse. The Greek for horse is hippos and kampos meaning sea-monster. The hippocampus also deals with memory – particularly short-term memory formation. It has a connection with the cortex, which deals with long-term memory and they have this system where the hippocampus transfers information to the cortex. Both are necessary for memory formation, and this is why if there is hippocampal damage, memory loss ensues. Its other connection is with the amygdala – this is why you may notice how much easier it is to remember things that are emotionally charged, or your dog always remembers that house with the yappy dog at the gate! The hippocampus therefore plays an important role in learning, whether our puppies and dogs are learning tricks or about the world around them. But the hippocampus is also involved in control of the HPA axis, which is a key element of the stress response. A well-functioning hippocampus is therefore vital for an appropriate and resilient stress response. Using Nutrition to Support The Stressed Dog Stress and the Hippocampus Unfortunately, there is data that links stress with reduced hippocampal volume. In short, stress results in a smaller brain. Stress suppresses neuronal proliferation. This smaller hippocampal volume can impede memory and learning, but also result in lower resilience to stress moving forward, and so the cycle continues. Luckily, there is evidence we can mitigate this damage. It seems there is a protein that can defend the hippocampus against shrinkage and support its regrowth and repair. It is known as BDNF (brain derived neurotrophic factor). One of two neurotrophins, BDNF promotes neuronal survival – it helps neurons grow, mature, and survive. It also increases energy efficiency in the brain. In humans, low levels of BDNF are linked with depression and in dogs, low levels of BDNF are associated with separation anxiety. But what’s really nifty is that there are a few things that can boost BDNF levels in the brain: Exercise: Study after study have demonstrated that voluntary exercise increases neurogenesis in the brain, particularly in the hippocampus. Regular walks are important for your dog’s well-being, cardiovascular and skeletal health, but they are also a great way to support their brain health. Interestingly, extreme exercise has been associated with impaired cognitive function due to the overload in reactive oxygen species causing oxidative stress – so balance is key! For that reason, rest is also essential to hippocampal health! The Importance of Sleep There is a diurnal rhythm of neurogenesis and as we know, dogs too are diurnal creatures (awake in the daylight and sleep largely at night). It is mainly at night that the hippocampus experiences growth due to the proteins that control the body clock. Enriched Environment Novel enrichment activities have been noted to increase BDNF levels in the brain – here we are looking for those new challenges for your dog; appropriately named, brain games. It may be puzzle games, learning new tricks, navigating a new trail or hunting a new treasure (food or toy). The key element here is novelty, whilst there are generalised benefits of prior exposure to a task, there are more significant improvements when it is a new experience. Boredom is regularly linked with low BDNF levels! Dog Brain Games Diet Last but not least, we are a nutrition page after all, but diet can influence BDNF levels too. Omega-3 Fatty Acids have been seen to normalise BDNF levels in the brain – they are also thought to be neuroprotective in that they protect neurons from death. Great sources of Omega-3 for the dog include fatty fish like sprats, sardines, mackerel, and salmon. Essential Fats For My Dog’s Diet Vitamin B12 When including both omega-3 and Vitamin B12 in the diet, higher levels of BDNF are found in the hippocampus and cortex. Vitamin B12 is a water-soluble vitamin that keeps nerve and blood cells healthy. It is also involved in energy production and more! There are no plant-sources of B12, it is produced in the gut of vegetarian animals, then absorbed into their blood stream, and makes its way around their body. Their tissue then provides B12 to whoever eats it. For that reason, sources of B12 include meat,
We all know what stress is, and over time we improve our ability to notice it in our pets, but in the heat of the moment, we often forget that it is in fact a biochemical process. For this process to occur, certain compounds are needed. In addition, for the state to pass, other processes need to occur. At a very basic level we can start to understand why we feel so tired after a particularly stressful day at work, but there is so much more to it, and this goes for our dogs too. So, let’s take a look at the process of stress, the nutrients it demands and how we can use this information to support our stressed dog. What is Stress? Well, the full biological stress response all starts in the brain. Let’s think of it in human terms to really get a handle on what’s going on. When someone confronts an oncoming car or other danger, the eyes or ears, or both (and parts of our peripheral nervous system) send the information to the amygdala, which is the area of the brain that deals with emotions. The amygdala interprets the images and sounds and sends a message to the hypothalamus. The hypothalamus is like the command centre. It communicates with the rest of the body through the autonomic nervous system (which controls such involuntary body functions like breathing, blood pressure and heartbeat. It also controls the dilation or constriction of key blood vessels and small airways in the lungs called bronchioles). The autonomic nervous system is further split into two branches, the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system functions like a gas pedal in a car and it triggers the fight-or-flight response. This response: Dilates pupils (to help you spot danger) Inhibits saliva production Dilates bronchia (to get more air into the lungs) Increases heart rate (to get more oxygenated blood around the body) Inhibits the activity of the digestive organs including the pancreas and gallbladder Stimulates the adrenal gland to release other stress related hormones Relaxes the urinary bladder After the amygdala sends a distress signal, the hypothalamus activates the sympathetic nervous system by sending signals through the autonomic nerves to the adrenal glands. These glands respond by pumping the hormone adrenaline into the bloodstream. As this circulates through the body, it brings on the physiological changes mentioned above. The heart beats faster than normal, pushing blood to the muscles, heart, and other vital organs. Pulse rate and blood pressure go up. You start to breathe more rapidly. Small airways in the lungs open wide so you can take in as much oxygen as possible. The additional oxygen is sent to the brain, which increases alertness. Sight, hearing, and other senses become sharper which all makes total sense if you are to escape a threat. At the same time, adrenaline triggers the release of glucose and fats from temporary storage sites in the body. These nutrients make their way into circulation, supplying energy to all parts of the body – equipping it to either fight or flee! The autonomic nervous system is the involuntary system and because the wiring is so efficient, the amygdala and hypothalamus start this cascade before we have even had a chance to consider what is happening or how we need to deal with it. As the initial surge of hormones subsides, the hypothalamus activates the second component of the stress response system. This is known as the HPA axis. It includes the hypothalamus, the pituitary gland, and the adrenal glands. The HPA axis relies on hormonal signals to keep the sympathetic nervous system “switched on.” If the brain continues to perceive something as dangerous, the hypothalamus releases corticotropin-releasing hormone (CRH), which travels to the pituitary gland, triggering the release of adrenocorticotropic hormone (ACTH). This then travels to the adrenal glands, which triggers the release of cortisol. Cortisol doesn’t deserve the bad rap it gets – it isn’t the instigator of the stress response, it’s the regulator – for as long as cortisol is present, the body needs to do something to protect itself. When the threat or stressor passes, cortisol levels fall. The parasympathetic nervous system (PNS) — which we can think of as the “brake” — then dampens or calms the stress response. The PNS is responsible for the “rest and digest” response that calms the body down after the danger has passed. This response: Constricts pupils Increases saliva production (saliva forms one of the first lines of defence in the immune system) Reduces heart rate Constricts bronchia Stimulates the organs of the digestive system like the pancreas and gallbladder Constricts urinary bladder The Recipe for Stress As you can see, there are a cascade of processes that occur which result in the stress response we are familiar with. The stress response is largely modulated by what we call catecholamines, and these include adrenaline, noradrenaline and dopamine and it therefore makes sense that if the stress response is consistently being activated, then the demand for these catecholamines increases. The creation of catecholamines starts with the uptake of the amino acid tyrosine. A few steps later, the conversion of tyrosine to certain catecholamines depends on the presence of vitamin B6. Later steps for the conversion to noradrenaline depend on the presence of copper. Vitamin C is also required in various enzyme activities in the synthesis of catecholamines. What this means is that stress increases the demand for these nutrients. But we must also consider the other side of the stress response – the rebalancing. For the body to return to homeostasis, catecholamines must be broken down. There are many genes responsible for this process, and not surprisingly, many nutrients are used in the process. Nutrients used to degrade catecholamines: Choline B6 B12 Folate Magnesium SAMe (made in the body from the amino acid, methionine) We can think of the stress response as a redirection of resources in many ways – it redirects attention
It makes sense that fussy eaters may be low in certain nutrients simply because they aren’t eating the required nutrients to thrive, but would you be surprised to learn that certain nutrients that we find low in fussy eaters could actually be contributing to the abnormal eating behaviour too? Let’s take a look at some of the nutrients we regularly target in dogs who are fussy eaters. 5HTP 5-hydroxytryptophan (5-HTP) is a chemical that the body makes from the amino acid tryptophan. After tryptophan is converted into 5-HTP, the chemical is changed into another chemical called serotonin (a neurotransmitter that relays signals between brain cells). But what we’re particularly interested in is that serotonin pathways modulate eating patterns and serotonin dysregulation is regularly implicated in eating disorders in humans. This is why selective serotonin reuptake inhibitors (SSRIs) are regularly used in the treatment of eating disorders. These medications keep serotonin hanging around a little longer, meaning it’s effects can be more noticeable. Animal data has also indicated that when you knock out serotonin receptors, eating disorders quickly follow. Findings Here You won’t find 5HTP in food, but you will find the amino acid tryptophan. Sources of tryptophan include turkey, chicken, pumpkin, sunflower seeds, and seaweed. 5HTP is generally found in supplement form. Zinc Zinc is required by humans and animals for many physiological functions, such as growth, immune function, and reproduction. Zinc deficiency induces several physiological issues including anorexia, growth retardation, dermatitis, taste disorder, and hypogonadism. There is increasing evidence that suggests zinc deficiency may be intimately involved with anorexia in humans; if not as an initiating cause, then as an accelerating or exacerbating factor. Study after study have highlighted that a decrease in appetite is the first visible sign of zinc deficiency, and it occurs well in advance of any other symptom. Subsequently, data has indicated that supplemental zinc rapidly stimulates food intake in zinc deficient animals. Findings Here To learn more about zinc’s role in the body and for some great sources to add to your dog’s diet, check out our blog: Why Zinc is So Important for Your Dog Vitamin D Humans with eating disorders regularly show a high prevalence of vitamin D deficiency and as it plays such a wide-reaching role through the body, this is certainly a nutrient to target in the fussy dog. Despite its name, Vitamin D is a hormone that promotes calcium absorption. Its role in bone health is why we often see humans with eating disorders suffering osteoporosis and osteopenia. Whilst Vitamin D is usually associated with skeletal issues, low levels are often associated with autoimmunity, infectious disease, diabetes, cardiovascular disease, obesity, neuromuscular disorders and cancer too. But it also plays a role in brain health, and this could influence eating behaviour. Vitamin D receptors are widespread in brain tissue, and it has a role in cell growth, neurogenesis, neuroprotection, detoxification, and reduction of inflammation. Findings Here To learn more about Vitamin D’s role in the body and for some great sources to add to your dog’s diet, check out our blog: The Importance of Vitamin D for Cats and Dogs Magnesium In a recent blog we explored how stress can be a factor for dogs who are fussy eaters and so it’s no surprise that magnesium status should be a consideration. Magnesium deficiency and stress seemingly come hand in hand. Many studies, both in pre-clinical and clinical settings, have investigated the interaction of magnesium with key mediators of the physiological stress response. It seems that magnesium plays an inhibitory role in the regulation and neurotransmission of the normal stress response. In addition, low magnesium status has been reported in several studies assessing nutritional aspects in subjects suffering from psychological stress or associated symptoms. This overlap suggests that stress could increase magnesium loss, causing a deficiency; and in turn, magnesium deficiency could enhance the body’s susceptibility to stress, resulting in a magnesium and stress vicious circle. Let’s compare the most frequent signs of both stress and magnesium deficiency: Symptoms of stress: Fatigue Nervousness Lack of energy Digestive discomfort Muscle tension Sadness Symptoms of magnesium deficiency: Tiredness Nervousness Muscle weakness Gastrointestinal spasms Muscle cramps Nausea/vomiting Sleep disorders Low levels of magnesium can be observed in response to mid- or long-term exposure to stress. A study conducted on guide dog candidates at different levels of a training program (elementary, intermediate, and advanced) showed the effects of temperature and physical stress on serum magnesium levels. First, it was demonstrated that serum magnesium levels were significantly lower in winter than in summer, suggesting an impact of seasonality on magnesium homeostasis. Secondly, it was noticed that physical exercise had a greater impact on serum magnesium levels of dog candidates in the elementary class compared to more trained ones; this highlights the role of stress as an adaptation and as the body adjusts, it uses less resources. Findings Here To learn more about magnesium’s role in the body and for some great sources to add to your dog’s diet, check out our blog: Why Magnesium is So Important to Your Pet We would always advocate a food first approach, but in the case of the fussy eater, this becomes a challenge. We would entice with palatable foods wherever possible, but supplementation may be a consideration in cases of low nutrient status or deficiency.

We can think of the gut like a roundabout; it has links to every system in the body. We have already explored the link between the gut and skin health, now we want to take a closer look at what we know as the gut-brain axis or GBA. This concept has gained traction over the last few decades and for good reason, but the question on everyone’s tongue… Does my dog have a gut-brain axis and what does this mean? Let’s see if we can answer that question. What is the Gut-Brain Axis? The gut-brain axis (GBA) consists of bidirectional communication between the nervous system, linking emotional and cognitive centres of the brain with intestinal functions. But research is indicating the importance of gut microbiota in influencing these interactions. The interaction between microbiota and the GBA appears to be bidirectional, through signalling from gut-microbiota to brain and vice versa. It is thought that this occurs in many ways, including neural, endocrine, immune, and humoral links. Neural Links Increasing evidence has found that the vagus nerve, a major neural connection between the gut and brain, plays a key role in facilitating signalling along the microbiota-gut-brain axis. The vagus nerve is the tenth of twelve pairs of cranial nerves found in the peripheral nervous system. Cranial nerves mainly innervate anatomical structures of the head and neck, but the vagus nerve is the exception to this rule; it extends from the brainstem through the neck and the thorax down to the abdomen. Because of its long reach throughout the body, it is often described as the “wandering nerve.” In the neck, the vagus nerve innervates the pharynx and larynx which are responsible for swallowing and vocalisation. In the thorax, it is the chief parasympathetic supply to the heart – this is what reduces our heart rate when we are recovering from a stressful stimulus. In the intestine, the vagus nerve regulates smooth muscle contraction and many secretory functions. The vagus nerve provides a critical link between the central nervous system and the enteric nervous system; the enteric nervous system is like the digestive system’s own nervous system – one that us or our dogs have little conscious control over. The vagus nerve link was largely established through studies utilising a surgical procedure known as a vagotomy which cuts or removes the vagus nerve to identify any resulting implications. Surgical vagotomy has been used to investigate the physiological role of the vagus nerve since the early 19th century. Surgical vagotomy has historically been carried out in humans to treat peptic ulcers. The procedure reduces stomach acid through its denervation of the cells that produce it. In more recent years, these procedures are less common, with patients opting for pharmaceutical alternatives. But what is interesting are the common side effects of vagotomy in humans which include interference with gastric emptying, increased and dysfunctional bowel movements and nutrient malabsorption resulting in deficiency. We almost found out about the role of the vagus nerve in digestive function by accident. The vagus nerve provides a link between the internal organs, including the gastrointestinal tract, and the central nervous system, with 80-90% of fibres being afferent (transmitting to the central nervous system) and 10-20% transmitting signals in the other direction, being efferent. The vagotomy procedure has implicated the gut-brain axis in cases of depression, stress resilience and anxiety. Vagus Nerve Signalling Within the small and large intestine you will find vagal afferents (nerve endings). These afferents can detect stretch and tension (how much food is in the gut), but they can also detect chemicals being absorbed across the epithelial layer. But what’s super interesting is that bacteria in the gut produce metabolites and neurotransmitters which can act directly on vagus nerve endings too! These nerve endings notice the metabolites and neurotransmitters and relay to the brain. We have found this through bacterial supplementation – for example, when certain bacteria are infused directly into the large intestine, vagal firing alters. So we know we can alter vagal firing through the population of bacteria found in the gut, but in our dogs, massage is gaining great traction at modulating vagus nerve function. Endocrine Links There is increasing evidence that suggests the gut as an endocrine organ, largely through its ability to produce and regulate multiple compounds that reach systemic circulation and subsequently act to influence the function of distal organs and systems. The biochemical complexity of the gut microbiota exceeds that of the brain, and many of the hormones produced by the microbiota are also neurotransmitters within the central nervous system. For example, γ-aminobutyric acid (GABA), the most important inhibitory transmitter in the brain is produced by several lactobacilli bacteria and monoamines such as noradrenaline, dopamine, and serotonin are also produced by certain strains of bacteria. We must also consider the role of the HPA axis. The hypothalamic-pituitary-adrenal axis (HPA) is the main stress response system. It is the neuroendocrine link between perceived stress and physiological reactions to stress. The use of germ-free animals has provided one of the most significant insights into the role of the microbiota in regulating the development of the HPA axis. It has been found that germ-free animals suffer aberrant responses to stress, but when they are then colonised with specific pathogen free faecal matter, their stress response becomes more balanced. Researchers have concluded that the microbial content of the gut is critical to the development of an appropriate stress response later in life and that there is a narrow window in early life where colonisation must occur to ensure normal development of the HPA axis. Immune Links Numerous studies in recent years investigating the gut-brain axis have demonstrated an important role for the gut microbiota in modulating brain development and function, with the immune system serving as an important coordinator of these interactions. Germ-free animals have regularly demonstrated that role of the microbiota in proper maturation of the immune system and immune regulation within the central nervous system is mediated by microglia, astrocytes, and
Sadly anxiety is as common in dogs as it is in humans. Anxiety is one of the body’s normal responses to stress; the problem is that our stress response hasn’t evolved with modern life and both us and our dogs can often feel overwhelmed. Alongside behavioural support for our anxious dog, we can look to support their stress response system from a nutritional standpoint. Let’s take a look at 5 of our top nutrients to support anxious dogs. 1. Omega 3 Fatty Acids Omega-3’s, in particular DHA, play critical neuroprotective and anti-inflammatory roles in the brain. Supplementation of omega-3 has been seen to: – Improve cognitive function Findings here – Reduce anxious symptoms Findings here – Reduce aggressive behaviours Findings here – Reduced stress-related hormone production Findings here What’s also super interesting is that omega-3 levels are regularly noted as being low in aggressive dogs. This isn’t indicating causation, simply an observation worth noting. Great sources of omega-3 fatty acids: Mackerel Salmon Sardines 2. Magnesium Often noted as the ultimate chill pill, magnesium is an essential nutrient that many are deficient in. Its low levels are regularly established in cases of depression in humans, so it is clear it plays a role in mood modulation and the stress response. Magnesium affects a number of neurotransmitter systems. Firstly, it inhibits excitatory neurotransmitters. Excessive excitation can lead to the death of brain cells, which affects the overall structure and functioning of the brain. Magnesium also acts as a cofactor in the serotonergic system. As we know serotonin is the happy chemical, and low levels of magnesium are regularly linked to low serotonin levels. Not only that, but magnesium excretion is increased during times of stress. Catecholamines and corticosteroids enhance the shift of magnesium from inside the cell to outside of the cell leading to increased urinary excretion. In turn, low magnesium levels increase the release of stress-associated hormones. This unfortunately creates a cycle of a reduced resistance to stress. Magnesium is found in leafy greens, nuts, and seeds. The ones packing the highest punch are spinach and pumpkin seeds. 3. Skullcap An herb used for insomnia in humans, it has a similar mechanism of action to Valerian. Skullcap is thought to be GABAergic. But it is also thought to influence serotonin receptors, which is why it has reported sedative and relaxing effects. A small, placebo-controlled, double-blind, crossover study of 43 human participants demonstrated that skullcap reduced symptoms of anxiety and depression in some individuals without causing an observable reduction in energy or cognition. In both cats and dogs, skullcap has been effective in general nervousness and excitability and in any condition where there is oversensitivity in the nervous system. 4. B-Vitamins Many of the B-Vitamins are involved in functions which directly impact the brain and nervous system. To single them out specifically, B12 and folate are reportedly low in cases of mood disorders in humans. B-vitamins can become depleted during times of stress, the more the body requires them for tasks the more they need replenishing. Stress also affects the lining in the stomach and compromises its function. Intrinsic factor is essential in B12 absorption but lack of production due to compromised function can significantly affect B12 levels. B-Vitamins can be found in eggs, liver, kidneys, chicken, red meat, tuna, mackerel, salmon, shellfish and dark green vegetables like spinach and kale. 5. Zinc In human literature, zinc is a trait marker of a mood disorder. Zinc deficiency is regularly associated with depression and anxiety, and supplementation often improves mood and cognitive function. We know zinc plays a role in mood because we find zinc enriched neurons in parts of the brain associated with emotions. Before we knew better, in rat studies, we found that increasing zinc levels reduced rat-fighting behaviour and when supplemented alongside antidepressant medication, rats developed improved resilience. Great source of zinc: Oysters, beef, chicken, pork, hemp seeds, shiitake mushrooms and red meat. We would always advocate a food first approach in supporting your dog, but there may be occasions where supplements will be beneficial. Calm Complex contains many of the nutraceuticals and herbs required to help calm the nervous system.

The 3rd of January is known as the Festival of Sleep, so here at My Pet Nutritionist, we thought we’d look into sleep in a little more detail. We often forget how important sleep is to overall health, for both ourselves and our pets. So let’s get to grips with why our dogs need it and some top tips for improving its quality, including whether there are nutrients that can help too! 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 also shown a significant reduction inactivity in dogs experiencing sleep restriction. Sleep can also mean the difference between life and death. Let’s take a trip back to the late 1800s. Whilst Coca Cola was sold in bottles for the first time in 1894, we still hadn’t made that much progress with animal testing. Marie De Manaceine was fascinated with sleep deprivation. She had established that mental disturbance resulted from partial insomnia, but she wanted to know more. So, in her Lab, she recruited puppies. 10 to be specific; aged 2, 3 or 4 months old. Whilst they continued to be fed by their mother, she kept them in constant activity. In short, she deprived them totally of sleep. After 96-120 hours, the puppies were irreparably lost. What is interesting (despite it being macabre), is that when puppies were starved, they could be saved after 20-25 days. This wasn’t possible when they were sleep deprived. Marie found that sleep deprivation significantly affected the puppy’s brains. When they were starved, the brain was left almost spared. But, in the absence of sleep, fat degeneration, blood vessel abnormalities and haemorrhaging occurred. In short, when the rest of the body is negatively affected by malnutrition, to an extent it can be saved. However, when the brain is affected, it is fatal. Sleep and The Brain The brain is the command centre for the nervous system. It is divided into three main sections; the brain stem which controls basic life functions, the cerebrum, which is the responsible for decision making and the cerebellum which controls movement. We know how a diet limited in lipids can detrimentally affect the brain and contribute to neurological disease, but sleep deprivation still had a worst impact in these puppies. Findings Here Many studies since Marie’s, have demonstrated that sleep loss (not deprivation) during development can result in reduced brain mass, neuronal death and subsequent behavioural problems. On the subject of the brain, it is pertinent to mention the glymphatic system. As we know, the body possesses its own sewerage system – the lymphatic system – but the brain has its own independent waste disposal system known as the glymphatic system. This system is gaining traction and being implicated in neurodegenerative disease. Researchers suggest that the glymphatic system may also function to help distribute non-waste compounds like glucose, lipids, amino acids and neurotransmitters. This system functions mainly during sleep, being largely disengaged during times of wakefulness – this suggests that amongst its many functions, sleep provides a state of activity that enables the elimination of potentially neurotoxic waste products. Your Pet’s Lymphatic System Sleep and Immune Function Sleep supports the initiation of an adaptive immune response. Slow wave sleep, and the circadian system act in concert to generate a pro-inflammatory response as well as reduced levels of the anti-inflammatory stress hormone cortisol. The hormonal changes in turn support the early steps in the generation of an adaptive immune response in the lymph nodes. In addition, sleep specifically supports memory formation in the immune system. The implication of sleep on immune response is demonstrated in various studies of vaccination, for example sleep on the night after experimental vaccinations against hepatitis A produced a strong and persistent increase in the number of antigen-specific Th cells and antibody titres. Findings Here Sleep and Cognitive Function 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 a new command were more likely to retain the command at a later date than dogs allowed to walk or play. Findings Here How Much Should Dogs/Puppies Sleep? Adult dogs, in a laboratory setting, when left, will sleep on average for around 13 hours per day. They are diurnal, which means they are active during daylight hours. Rest occurs during dark periods with activity increasing the two hours before light. Dogs have a natural rest period around noon and then reduced activity during the afternoon. Findings Here Puppies can sleep anywhere between 18-20 hours per day. Again, you will notice higher activity in the morning and then rest, with reduced activity around noon and into the afternoon. Interestingly, the experiences that your dog has can affect the type and quality of sleep they experience though. Studies have found that after a negative experience, dogs will fall asleep more quickly. It is thought that this is a protective sleep, in response to stress. This should be a consideration for all dog owners. It’s all too easy to attribute an “exhausted” dog to the busyness of the day. Be mindful, their sleeping habits could be more indicative of their experience. Findings Here In humans, lack of sleep is classed as a major stressor. It wouldn’t be too much of a stretch to suggest similarly for our canine companions. Below average sleep quotas are linked with anxiety, aggression, decreased response to reward, lower frustration tolerance and low resilience. Sleep disturbances affect hormone levels; specifically stress hormone levels. Animals experiencing sleep disturbance demonstrated less grooming behaviour and opt for fewer enrichment activities, and we know how important these activities are for stress regulation in dogs. Findings Here Ideas To Help Your Puppy Sleep If your
Christmas can be a little chaotic at the best of times; some of our companions love the attention from all the visitors, but some can get a little overwhelmed. There are many strategies that we can employ for our furry friends to get through this time of year unscathed, but we can also support them nutritionally too! Here are our top nutritional tips for canines this Christmas. Max Out On Magnesium! Magnesium excretion is increased during times of stress. Catecholamines and corticosteroids enhance the shift of magnesium from inside the cell to outside of the cell leading to increased urinary excretion. In turn, low magnesium levels increase the release of stress-associated hormones. This unfortunately creates a cycle of a reduced resistance to stress. Offer your dog plenty of magnesium rich foods like leafy greens, nuts and seeds. Time for Tea! L-Theanine is seen to facilitate the generation of alpha waves which are indicative of a relaxed but awake and alert state. L-Theanine helps regulate the usual stress responses like increased blood pressure, heart rate and cortisol secretion and it’s found in our trusty tea! Green tea packs the highest content, so brew up a cup of decaf and share it with your pooch this Christmas. Dose up on D! Did you know that Vitamin D deficiency is associated with increased anxiety scores? Whilst we know it plays a role in immune function, it also contributes to cognitive function along with mood and behaviour. Add plenty of fresh foods containing Vitamin D to your dog’s bowl, including: liver, fish and eggs! Mushrooms are a great source too, and if you keep them in the windowsill, you’ll get even more Vitamin D too! Always remember to saute mushrooms before feeding. Build Up Your B’s! B vitamins are heavily involved in the synthesis and breakdown of stress hormones. Whenever we or our dogs are stressed, we release a cascade of hormones that help us manage the threat in front of us. When the threat has passed, those hormones need to be broken down so our bodily functions can return to normal. It goes without saying, the more often our bodies have to do this, the higher the demand for B vitamins (and more). B vitamins are water-soluble, meaning they need to be replenished daily, and this is even without any stressors we may be facing. Offer your dog plenty of sources of B vitamins in their bowls like seafood, poultry, red meat, leafy greens and seeds! Our wonderful Calm Complex provides all of the above. br] br] Fill up on Ferments! This may not apply to all dogs; especially if you are tackling an itchy issue, but there is increasing data highlighting that poor microbial diversity in the gut is linked with increased scores of anxiety. A great way to support microbial diversity is to ensure the diet contains both pre and probiotic foods. Prebiotic sources include: mushrooms, dandelion greens, garlic, burdock root and more. Probiotic foods include fermented products like kefir. Aside from certain nutrients, we also know how important chewing is in engaging the parasympathetic nervous system – which is the rest and digest side of the stress response. This is why offering whole foods, which take some chewing, is great for your dog’s physical and emotional health. Why Dogs Need To Chew Other top (non-nutritional) tips for supporting your overwhelmed canine this Christmas: Set up a safe space – this can be a covered crate or simply a quiet spot somewhere in the house. Try to maintain as much of the routine as possible, Head out on walks when it’s quiet – when everyone is driving home for Christmas at the same time, it can get a little unnerving for your anxious pooch.

Sadly, anxiety is as common in dogs as it is in humans. Anxiety is the body’s normal response to stress; the problem is that our stress response hasn’t evolved with modern life and both us and our dogs often feel overwhelmed. A stressful situation can bring about a whole cascade of biological responses and it all starts in the brain. When someone confronts an oncoming danger, the eyes or ears, or both (and parts of the peripheral nervous system) send the information to the amygdala, which is the area of the brain that deals with emotions. The amygdala interprets the images and sounds and sends a message to the hypothalamus. The hypothalamus is like the command centre. It communicates with the rest of the body through the autonomic nervous system, which controls such involuntary body functions like breathing, blood pressure and heartbeat. It also controls the dilation or constriction of key blood vessels and small airways in the lungs called bronchioles. The autonomic nervous system is further split into two branches, the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system functions like a gas pedal in a car and it triggers the fight-or-flight response. The parasympathetic nervous system is like the brake pedal; it slows everything back down and returns the body to homeostasis, or as we know it, rest and digest. In cases of anxiety, the sympathetic nervous system remains activated, it’s a form of chronic stress. So, when tackling anxiety, we need to take the paw off the gas pedal, and firmly place it on the brake. It goes without saying that removing the trigger that causes the stress or anxiety is of paramount importance, but in many cases, like on bonfire night, we can’t remove it in its entirety. In cases of separation anxiety too, we often want to take the edge off the response in order to work through a behavioural programme. 1) Thunder Jackets These jackets work under the premise that applied pressure calms nervous system function and many owners report success. A study in the Journal of Veterinary Behaviour explored a range of methods for managing firework fear in dogs with the following efficacy: Pressure jackets 44% Counterconditioning 70% Relaxation training 69% Noise CDs 55% 2) Chamomile Chamomile (Matricaria recutita) is one of the most widely used herbal remedies in the world. While there are many varieties of chamomile, Roman (A. nobilis) and German (M. recutita) are the most widely used forms. These are members of the Compositae (Asteracae) family. German chamomile is considered the more potent and is most widely used. It has many medicinal uses including carminative (anti-colic), antiseptic, and anxiolytic. Chamomile is notorious for its continuous bloom! Chamomile serves as a safe, general purpose calming herb that doesn’t taste too shabby either. In human tests it has been effective in mild to moderate generalized anxiety disorder. Findings Here It can be served as a tea, but is also available as an oil infusion, tincture, salve and ointment. 3) Valerian Many will recognise valerian for its similar smell to old, dirty socks! Valerian (Valeriana officinalis) is commonly used for the treatment of insomnia and anxiety disorders in humans. It has a mechanism of action similar to benzodiazepines; however, instead of binding to the gamma subunit like a benzodiazepine, it appears to bind to the beta subunit on the GABA-A receptor instead. Regardless, it has the same effect on chloride movement into the neuron when the major inhibitory neurotransmitter, GABA, binds to the GABA-A receptor, thereby causing a hyperpolarized state. In addition, valerian has also been shown to decrease the removal or metabolism of GABA, thereby allowing GABA to stay around longer and do it’s thing. And as we know, GABA is the brake like neurotransmitter in the body. Findings Here Valerian is available in tincture, tea and fresh or dried root. 4) Skullcap Another herb used for insomnia in humans, it has a similar mechanism of action to Valerian. Skullcap too is thought to be GABAergic. But it is also thought to have an effect on serotonin receptors, which is why it has reported sedative and relaxing effects. A small, placebo-controlled, double-blind, crossover study of 43 human participants demonstrated that skullcap reduced symptoms of anxiety and depression in some individuals without causing an observable reduction in energy or cognition. In both cats and dogs, skullcap has been effective in generous nervousness and excitability and in any condition where there is oversensitivity in the nervous system. Skullcap is usually found in dried herb or tincture form. 5) St John’s Wort St. John’s Wort (Hypericum perforatum) is an herbal medication that consists of anthraquinones, which have displayed anti-inflammatory and anti-cancer effects. It has also been used as an antidepressant in humans. It derives from a flowering plant found in Europe and Asia. It is usually found in capsule, tea, or liquid extract. It is thought that St. John’s Wort acts as a serotonin reuptake inhibitor. This works to reduce the uptake of serotonin at neuronal synapses, as well as dopamine and norepinephrine. One of the primary adverse effects is the risk of an increase in serotonin when combined with certain antidepressants and the inhibition of monoamine oxidase. Be cautious of signs including tachycardia, increased blood pressure and mydriasis. There may also be a fever. It is however, often used in dogs with fear-based or separation anxiety. A great product for anxiety is our Calming Complex Calm Complex The introduction of any new supplement or herb is always done best under the guidance of a practitioner. If your dog suffers with anxiety, it’s crucial to work within a behaviour programme to tackle key triggers. However, there can also be a multi-modal approach and our services may be of use.

Here at My Pet Nutritionist, we work with pet guardians who would move heaven and earth for their cat or dog. Our pets become part of our family; it’s why we want to do the best for them. Do our dogs know this? Is that why we perceive them as being so loyal? Or is it just their nature? Is it quite as simple as us fulfilling their needs, or are there some feelings involved? To get to the bottom of this, it makes sense to go back to the beginning and look at how we actually ended up with these balls of fluff on our sofa. Our modern-day dog is a result of the domestication of wolves. We only have a ballpark figure as there is some confusion as to when this actually occurred. Somewhere between 14,000 -135,000 years ago gives us an idea though. What is clear, is that it happened based on mutual gain. Wolves would seek out food and realise that human camps were a great place to scavenge. Humans accepted the wolves for either protection or companionship. And so, it began. Wolves who were more accepting of humans would access more food and therefore stood a better chance of surviving. They would then produce off-spring who would follow in their parent’s footsteps and learn that humans = food. Humans would accept friendly wolves and likely kill aggressive wolves thereby also influencing which wolves would survive. So very early on, wolves learned that loyalty to humans equalled safety and food. We can almost suggest that we have selectively bred dogs who are dependent on us. Studies have shown that if you present a dog with an impossible task, they will attempt it, but soon look to their owner as if to ask for help. Cats on the other hand will continue to attempt the task in ignorance of their owner. Findings Here So, are dogs loyal because they have to be? Not necessarily. Studies have also shown, that when a dog is forbidden food, he will obey the wait command for as long as the commander has direct sight of the food. If the commander closes their eyes, the dog will disobey and take the food. Findings Here This could suggest that dogs are loyal because they think we want them to be. Dogs are incredibly good at reading human cues especially when we are upset. Dogs show more interest in a human when they are crying as opposed to simply humming or talking. Dogs will nuzzle, sniff and lick both their owners and complete strangers. Findings Here Of course, you could argue that dogs have simply learned to do this. Chances are, if you’ve been upset and your dog has come over to you and nuzzled you, you’ve perhaps smiled, or made a fuss of them. Dogs learn from the consequences of their behaviour, so they may have simply learned that by doing this, they get a happy response with a pat on the head. This isn’t a hard push when we learn that along with humans, when dogs are interacting with their owners, their oxytocin levels also increase. Oxytocin is released during pleasurable social experiences, often dubbed the love or cuddle hormone. So, it does go both ways. When we interact with each other, we both get an oxytocin surge which makes us both feel warm and fuzzy! Win win! It does therefore make sense that a dog’s loyalty is a way to keep us around – especially if it makes them feel good. A recent study has shown that dogs have evolved new muscles around their eyes which allows them to raise their eyebrows, so to speak. This is something wolves cannot do. It is suggested that this raising of the eyebrows triggers a nurturing response in humans because it makes the dog’s eyes seem bigger and look sad! It seems that dogs are still evolving to “need” us more, or at least keep in our good books! Findings Here So, it seems that dogs are loyal because it means they get what they need, like food and shelter. But they also feel just as warm and fuzzy when they interact with us. They’ve learned to read our behaviour and what they need to do to keep us around. What is particularly interesting is that they are still evolving to develop features which will keep us nurturing them. Could this suggest that their loyalty may only get stronger? The take home? Even if you have the most independent and aloof dog, they still depend on us to care for them. This is a huge responsibility, and one most of us don’t take lightly.

We all understand the importance of taking our dog for that daily walk – not only to provide physical exercise, but to sniff, play and have a stroke from the neighbours. Yet, what we sometimes forget, is the importance of mental stimulation for our faithful friends. Not only are brain games known to help ward off cognitive decline, which is crucial for our ageing pets but brain games help reduce stress and manage anxious behaviours too! Findings here Time and time again,when given the choice, animals will always choose a more complex environment. So, as we look to support optimal health in all ways we can here at My Pet Nutritionist, we thought we’d compile some of our favourite brain games for dogs! 1) Name Game! Here, we are teaching our dog the name of all his toys. Encourage your dog to retrieve one of his toys. As soon as he collects it, label the toy, “ball!” “rope!” etc. Repeat and praise as he retrieves it. Start with one or two toys. If he doesn’t falter to retrieve the correct toy, introduce more toys. This game is testing his memory as well as his recognition. This game is perfect for those toy orientated dogs – providing they don’t choose to run off with the toy and ignore you. If this happens, calmly ignore them until they return. Remember, you are praising and providing attention for the behaviour you want to see! You can always use this game to introduce tidy up time – as you ask your dog to retrieve specific toys, hold your hands over an allocated storage box. As he brings the toy to the box, label the behaviour “tidy!” Praise and reward. 2) Spin the bottle! Perfect for those food orientated pooches. You will need: A sturdy plastic bottle (we know it’s not eco, but not so bad if you are able to recycle) A cross bar – a piece of doweling or bamboo Pierce holes on opposite sides of the bottle – large enough so you can push the cross bar through. You should be able to hold the cross bar and the bottle will spin around on the bar. Put some small treats into the plastic bottle to start with, so it’s easy for your dog in the first attempt. Food orientated pooches will immediately sniff out the treats in the bottle and attempt to get them out. They need to learn to spin the bottle, so the treats fall out. Once they have figured out the basic idea of the game, you can make it more difficult by using a range of sized treats, so some fall out quite easily, others don’t. Or you can move you hands to the cross bar and provide some resistance as they spin the bottle. Remember to make allowance for any additional food/treats in allocated mealtimes. It can soon add up! 3) Gone Potty Another one for those food orientated pooches and another one to make them think. What you will need: High value treats 3 plastic plant pots Start with one pot upside down and place a treat underneath it. Allow your dog to watch you place the treat. Encourage your dog to knock the pot over to get to the treat. Introduce another plant pot – allowing your dog to watch which pot you put the treat under. Eventually, you can be working with the three plant pots. Your dog has to figure out where the treat is – he may have watched you, or he may have sniffed it out. Watch for impatient dogs who just knock all the pots over to find it; a different game may be best for them; brains over brawn after all! 4) Shy Dog! What you will need: Post it notes Treats Place a post-it-note on your dog’s nose. He should instinctively paw at it to remove it. As he does, praise and reward him. Repeat. Don’t worry if he removes it, just apply another one. As he paws to remove the note, label the behaviour “shy dog” or whichever command you think fits. Repeat. Eventually, he should be a shy dog, on command. 5) Treasure Hunt A super-easy brain game is the good old treasure hunt. First of all, figure out which reward your dog places a higher value on. Offer him food and toy rewards on the ground. Watch the reward he chooses first. This will be your treasure. Whichever he opts for, you are going to hide it around your home. Place treats/toys behind cushions,curtains, under tables or stools, behind doors, in boxes etc. Just be mindful that you place the treasure where it’s safe to access and you’re sure your dog won’t just barge their way around your home to find it! You may have to show your dog where you are hiding the treasure when you first introduce this game, just until they get the hang of it. You can build tidy up time into this game if you are using toys too! Inadequate mental stimulation can present in many ways from pacing and destruction to self-licking and self-harm. To support our dog’s health and well-being, we need to provide for both his physical and emotional needs. Brain games are a great place to start! Whilst we may conjure up images of our dog’s equivalent of Sudoku, brain games simply provide cognitive challenge. The important thing is to provide just enough challenge – if your dog seems disinterested, try a different game, if they seem frustrated, end the session with something you know they can do, and try to approach the game in a different way next session. As Ignacio Estrada poignantly suggested, “if a child can’t learn the way we teach, maybe we should teach the way they learn.” The same applies to our dogs. Thanks for reading! Team MPN x
