I have listened to and taken notes on dozens of hours of lectures by integrative veterinarians about gut health. I have collected more notes than I could possibly list. The deeper I went, the more one question stayed with me: how much can we genuinely do for our dogs’ intestines, and how much of the popular advice is still only a hypothesis?<\/p>\n
A dog may occasionally have soft stools, gas or vomiting, but problems can also show up as weight loss, a poor appetite or changes in behaviour. Not every digestive upset is a chronic intestinal disease, and not every skin problem starts in the gut. Still, the gut is part of a much larger system: digestion and nutrient absorption, immune activity and constant communication with nerves and microbes all happen there.<\/p>\n
Here I am bringing together what I have learned from both integrative and conventional veterinary approaches. I am not looking for a miracle supplement to solve everything. I want us to better recognise when daily habits can help, when a diet change makes sense and when thorough diagnostics are needed. My greatest lesson has been that progress often begins by asking the right question.<\/p>\n
A healthy gut is not a sterile tube. The intestinal lining, digestive secretions, immune system and microbiome work together. The microbiome includes microorganisms and their genes; what matters is not just which organisms are present, but also what they eat and which metabolites they produce. For example, when microbes ferment certain fibres, they can produce short-chain fatty acids involved in regulating the intestinal environment.<\/p>\n
Every dog’s microbiome is individual and changes with diet, age, medication, environment and illness. A difference in the proportions of bacteria between study groups does not automatically mean that a particular bacterium caused a disease. Nor is there a single universal ‘ideal microbiome’ that every dog must achieve. The aim is a functioning gut, not the longest possible list of supplements.<\/p>\n
Cells lining the intestine form a protective barrier that regulates the movement of substances from the intestinal contents into the body. Inflammation and certain diseases can change intestinal permeability. Researchers use different methods to measure it, but in everyday language the phrase ‘leaky gut syndrome’ is often used far more broadly than a clearly diagnosed veterinary disease.<\/p>\n
Integrative veterinarians such as Gary Richter and Ruth Roberts have highlighted connections between the intestinal barrier, food, microbes and immunity. The underlying mechanisms are plausible and have been studied in several conditions. That does not establish that every case of anxiety, joint pain, itchy skin or thyroid disease is caused by one shared barrier problem. Persistent symptoms deserve consideration of other explanations too.<\/p>\n
During stress, the autonomic nervous system changes its activity. This can affect intestinal movement, sensitivity, secretions and sometimes the microbiome. One dog gets soft stools after an exciting event; another loses interest in food. But saying that digestion simply ‘switches off’, all enzyme production stops or food becomes stuck in the intestines is too absolute.<\/p>\n
Communication between the brain and the gut works in both directions. Stress can aggravate digestive symptoms, but chronic nausea, abdominal pain or inflammation can also make a dog more restless and sensitive. This is why neither ‘just calming the dog down’ nor ‘just changing the food’ solves every problem.<\/p>\n
One of the simplest supportive measures is a predictable daily routine: calm meals, adequate rest, opportunities to sniff and move, and a day that is not one endless burst of excitement. If a dog feels unsafe while eating, start by looking at its feeding area and competition with other dogs.<\/p>\n
For a few days, record meal times, stool quality, vomiting, walks, exciting events and any food changes. Patterns may suggest a cause, but blood in the stool, repeated vomiting, marked abdominal pain, dehydration, lethargy or weight loss need veterinary assessment.<\/p>\n<\/div>\n
What a dog eats influences stool quality and microbial metabolism. Digestibility, fat content, proteins, an appropriate amount of fibre, calorie density and whether the entire diet supplies complete nutrition can matter more than any marketing claim on the front of a bag.<\/p>\n
I like the idea of offering real foods where they suit the dog. A small portion of a safe vegetable, an egg or another suitable addition can add variety and enrich mealtimes. But ‘the more, the better’ is not a sensible rule. Replacing a large share of complete food with random extras changes the balance of vitamins and minerals. That is particularly important for puppies, growing large breeds and unwell dogs.<\/p>\n
Some dogs do well on a high-quality dry food, others on wet food or a carefully formulated home-prepared diet. A dog with chronic gastrointestinal disease may need a diet based on a specific protein, hydrolysed protein, high digestibility, additional fibre or reduced fat. These are not competing ideologies; they are tools for different purposes. The quality of ingredients and the clinical function of a particular diet need to be considered separately.<\/p>\n
The 2026 ACVIM consensus guidance on canine chronic inflammatory enteropathy recommends a carefully selected and strictly followed dietary trial as an early step in clinically stable dogs. Randomly mixing something new into the old food for one week is generally not enough. The response is assessed, the diet type is chosen deliberately and, if needed, different diets are trialled in sequence.<\/p>\n
Yes. Different types of food can form part of the same overall diet when quantities, nutrient balance and the dog’s tolerance are considered. There is no sound clinical evidence that dry food and raw meat necessarily upset digestion when fed at the same meal because they move through the system at different speeds. Dr Conor Brady has also pointed out that the digestive system adapts to different food sources.<\/p>\n
However, claims about digestion must be distinguished from genuine food-safety questions. Raw animal products can contain Salmonella, Listeria and other pathogens. The risk extends to the people handling the food, especially if the household includes young children, older people, pregnant women or people with weakened immune systems. Freezing does not automatically make raw meat free of microbes. For an ill or immunocompromised dog, I would favour a cooked option when possible.<\/p>\n
I have never felt the need to argue that every dog should be fed a 100% raw diet. Formulating a balanced raw diet at home is difficult, and integrative veterinarians also recognise that not every commercial raw diet is nutritionally balanced.<\/p>\n
For many households, a well-considered combination of foods is a more realistic option. If raw meat or bones are included, owners must assess the risks of infection, choking and dental injury. Some integrative veterinarians advise leaving a few hours between feeding bones and dry food, but that interval has not been proven to prevent stomach problems or microbial contamination.<\/p>\n
There are links between the gut, skin and immune system, but allergy, intolerance and chronic inflammatory enteropathy cannot be diagnosed simply from a list of symptoms. You may hear the claim that a ‘real allergy’ must always cause anaphylaxis. That is incorrect. Food allergy in dogs can cause persistent itching, ear infections or digestive symptoms; a severe immediate hypersensitivity reaction is not a requirement for diagnosis.<\/p>\n
Integrative veterinarian Ruth Roberts has recommended rotating home-prepared menus and later reintroducing foods one by one. Rotation can add variety for some healthy dogs. But if the aim is to identify a suspected food reaction, switching between three recipes every day may make it much harder to identify the culprit. In that situation, a structured, sufficiently long and strictly followed elimination trial is needed, followed by a controlled challenge once symptoms improve. Skin-related trials may take around eight weeks or longer; gastrointestinal signs may respond sooner and the duration depends on the diagnosis.<\/p>\n
There is no proven universal rule that a food must be excluded for precisely 18 months or that a sensitivity will necessarily disappear afterwards. Decisions depend on the reaction and the veterinary plan. Nor can hair analysis, saliva tests or arbitrary blood panels be treated as definitive food allergy tests.<\/p>\n
Dogs encounter their environment through their noses, mouths, skin and paws. Air pollution, pesticide residues, road dirt and contaminants in some foods are real exposure routes. In integrative discussions, Gary Richter and Christina Chambreau have emphasised how dogs’ proximity to the ground and their habit of licking their paws could increase certain exposures. It is a useful perspective, although without actual measurements we cannot claim that all dogs necessarily absorb more toxins than humans.<\/p>\n
It is also untrue that heavy metals cannot be absorbed through a healthy intestine. Absorption depends on the substance, quantity and chemical form; an intestinal barrier does not render lead or mercury harmless. When choosing fish, species and the potential accumulation of contaminants matter more than claiming that every bottom-dwelling fish is dangerous. Integrative veterinarians often advise choosing shorter-lived fish, because their heavy-metal burden is generally lower.<\/p>\n
Many precise percentages and claims circulate about glyphosate, such as the suggestion that 70% of rain contains it or that one particular lawn treatment increases a dog’s lymphoma risk by exactly 70%. Those figures should not be repeated without checking the study location, chemicals involved, exposure measurement and design. Earlier associations between lawn-care chemicals and canine cancer do not automatically prove a specific effect of glyphosate alone. Equally, that does not prove glyphosate plays no role.<\/p>\n
Practical precautions are simpler and less sensational: keep dogs off freshly treated grass, especially if they might lick or eat it; follow the product’s safety instructions; wipe paws when useful; offer clean drinking water; and keep chemicals and poisons out of reach.<\/p>\n
If poisoning is suspected, avoid improvised ‘detox’ courses using zeolite, clay powders or large amounts of dandelion. Their binding effects inside a dog’s body, suitable doses and interactions with medicines are not sufficiently clear. Actual poisoning needs urgent veterinary help, not a wait to see whether a probiotic or adsorbent will fix it.<\/p>\n
Traditional Chinese Veterinary Medicine (TCVM) classifies animals using patterns described as warm, cold, dry or damp. Foods are also described as ‘warming’ or ‘cooling’ within this framework. Integrative veterinarians may use this as an additional perspective when personalising a menu. These categories should not be confused with physical temperature, nutrient analysis or a clinically proven treatment effect in dogs.<\/p>\n
Based on our observations, Oscar would be considered a relatively ‘warm’ dog within this framework, while Faddu and Irene’s dog Fenton would be more ‘cool’. Pekwa also seemed ‘warm’ by these criteria. This is my observation and a traditional interpretation, not a diagnosis established by blood tests or a controlled trial. Sometimes the framework simply encourages closer attention to how a particular dog responds to different foods.<\/p>\n
TCVM food lists may classify chicken, lamb, oats, pumpkin and sweet potato as warming, while turkey, duck, courgette, broccoli and barley are sometimes listed as cooling. I would not treat these lists as medical prescriptions. For a dog with pancreatitis, chronic kidney disease or inflammatory bowel disease, clinically relevant limitations on fat, protein, minerals and individual tolerance must come first. Calling chicken ‘warming’ does not make it suitable for every dog with pancreatitis, nor does it mean chicken is unsuitable for all of them.<\/p>\n
A probiotic is not simply another word for ‘good bacteria’, and a prebiotic is not just any vegetable. A probiotic is a specific live microorganism shown to benefit health at an appropriate dose; a prebiotic is a substance selectively used by host microorganisms that confers a health benefit. Effects depend on the strain, dose and condition. Some products may help in particular forms of diarrhoea or chronic intestinal disease, while other products have little meaningful clinical evidence.<\/p>\n
The 2026 ACVIM chronic inflammatory enteropathy guidance considers the role of pre-, pro- and synbiotics limited, although they are generally well tolerated. A particular eight-strain preparation or, in some circumstances, Saccharomyces boulardii may be considered alongside other treatment, but neither replaces a dietary trial, diagnosis or necessary medication. Studies of faecal microbiota transplantation are interesting, but this is not a routine home technique for ‘restoring the microbiome’.<\/p>\n
Omega-3 fatty acids have biologically plausible effects on inflammatory mediators. Whether they help a particular intestinal disorder depends on the problem and the dose; no one can promise that every oil will cure chronic intestinal inflammation. Added fat can worsen some digestive diseases, particularly pancreatitis. Likewise, I would not automatically give colostrum, clay or herbs simply because they appear in a holistic protocol.<\/p>\n
Often the biggest help is to stop trying ten things at once. If one day we change the dry food, add three herbs, start a probiotic and alter the walking routine, a week later we will have no idea what actually made a difference.<\/p>\n
Persistent diarrhoea, vomiting, weight loss, blood in stools, marked loss of appetite or lethargy are not a ‘detox reaction’ to endure at home. Puppies, older dogs and animals with other diseases can deteriorate faster. Severe abdominal pain, collapse, repeated unproductive retching and signs of dehydration call for urgent veterinary attention.<\/p>\n
