Gastrointestinal issues are one of many common reasons for owners to bring their pets in to see a vet. Dogs with sensitive stomachs tend to have repeated occurrences of loose stools, gas or vomiting. These could be caused by the wrong diet, parasites, infection, food allergies, or other medical conditions like pancreatitis. Dietary management is the most effective treatment for these chronic 'on and off' digestive upsets.
Read more about the symptoms and causes for a sensitive stomach and things we can do to help.
Why is choosing the right sensitive stomach food important?
It is crucial to have your veterinarian investigate the underlying cause for the ongoing gastrointestinal issues. Depending on the problem, your vet may advise a specific veterinary therapeutic diet. Dogs with food allergies should be fed a hydrolyzed diet or novel protein diet to minimise risk of an adverse reaction. Dogs with pancreatitis, on the other hand, must eat a fat-restricted diet to avoid recurrence.
Four reasons why it's important to choose the right sensitive stomach food for dogs are:
- Medical conditions: Does this food help treat your dog's medical condition? Follow your veterinarian's advice and guidelines on nutritional therapy.
- Digestibility: An inflammed, unhealthy gut will benefit from a highly digestible diet that makes it easy for the body to absorb nutrients
- Formulated for gut health: Has this diet been formulated specifically for pets with sensitive stomachs? These diets are often backed by scientific research and may contain ingredients like prebiotics to improve digestion.
- Protein: Dogs with a known food allergy should avoid foods containing that ingredient (i.e. beef, chicken). Prescription hypoallergenic (hydrolyzed protein) or single protein source diets are recommended for food trials and long term feeding.

This prescription food contains ActivBiome+ ingredient technology, which is a unique blend of prebiotic fibres clinically proven to rapidly activate the gut microbiome and promote healthy balance. By restoring a positive gut environment, digestive function is improved resulting in regular and healthy stool quality.
In addition, Hills i/d prescription food includes their 'S+OX Shield', helping to protect your dog from the risk of urinary crystals. The food is formulated such that struvite and calcium oxalate stones are unlikely to form in an unfavourable environment.
What our customers say: "Excellent for a dog with digestive issues. This has really helped my elderly Lhasa Apso with his digestion. He likes the food and it is keeping him happy and healthy."
What our vets say: "Hill's i/d low fat is clinically formulated and tested to support your dog's digestion. As the name suggests, this diet contains a very low percentage of fat - which is important for fat-responsive digestive conditions. Dietary fat is often a trigger for dogs prone to pancreatitis, and this diet makes it simple for owners to manage and prevent recurrence of this painful condition. I/d also contains prebiotic fibres to support a healthy gut microbiome and improve digestion, making it suitable for long-term feeding." - Dr. Kes
Royal Canin Gastrointestinal Low Fat
Pros
- Formulated for dogs suffering from gastrointestinal disorders

Similar to the Hills Prescription i/d low fat diet, the Gastrointestinal contains very low fat content (7%) to support dogs with hyperlipidemia and pancreatitis. These conditions require a fat restricted diet for effective management. Bear in mind that such diets are not recommended for dogs that are pregnant or nursing, or for puppies as they have different nutritional requirements.
This diet contains balanced levels of fibre and added prebiotics to aid digestive function and improve gut microflora. The Royal Canin Gastrointestinal Low Fat is suitable for management of gastrointestinal disorders including acute or chronic diarrhoea, exocrine pancreatic insufficiency, bacterial overgrowth or protein-losing enteropathies (from inflammatory bowel disease or diseases such as parvovirus).
What our customers say: "Because my little dog had pancreatitis she was put on a restrictive diet. This food fits the bill and she is fine on it. I love the efficient service Pet Circle provides too. Cheaper than buying from the vets."
Best Hydrolyzed Diets
Hills Prescription Diet Zd Skin And Food Sensitivities
Pros
- Used to diagnose and manage food allergies in dogs
- Hydrolysed poultry liver and single carbohydrate source
- Omega 6 and antioxidants for healthy skin
- Gold standard food allergy diet
- S+OX Shield, reduces risk for urinary stones
- Lower fat content
Cons
- Costly, prescription only
- Not suitable for growing puppies, pregnant or lactating dogs
Hills Prescription Diet Z/d is made with hydrolyzed protein and single carbohydrate source, making it highly unlikely to trigger an adverse reaction. Hydrolyzation is a process where the protein has been broken down into its amino acid components to eliminate an immune reaction. Dogs with food allergies often show signs of skin irritations. Hills z/d includes omega 6 fatty acids to support the skin and coat, as well as antioxidants to maintain a healthy skin barrier.
During the manufacturing process, extra steps are taken to ensure that there is no contamination with other protein sources. This is achieved through rigorous testing and cleaning of all production equipment to formulate these prescription diets under pharmaceutical grade standards.
Prescription diets such as the Hills z/d which have been scientifically formulated for dogs with food allergies and hypersensitivities are the gold standard therapeutic diets.There are other hydrolysed diets available - Royal Canin Hypoallergenic and Anallergenic, which will be discussed next.
What our customers say: "It's highly palatable, and has a 100% approval rating from my French Bulldog. So it should be a great food to use for a 3 month food allergy trial."
Royal Canin Anallergenic
Pros
- Made with hydrolysed feather protein (novel source)
- Lowest molecular weight protein on the market
- Purified starch as carbohydrate source
- High levels of omega 3 and 6
- Gold standard food allergy diet
Cons
- Expensive
- Prescription only food
- Not recommended in pregnant, lactating, growing dogs, or in dogs with pancreatitis or hyperlipidaemia
Royal Canin Anallergenic is formulated with highly hydrolysed poultry feather protein. As the protein is reduced to such a small size and sourced from a novel origin, it is extremely unlikely to trigger an adverse food allergy reaction. Can be used as an elimination diet to diagnose suspected food allergies, and for long term therapy if needed.
This diet has been formulated to help strengthen the skin barrier against allergens and omega fatty acids are included to nourish the skin and coat. Although this is a gold standard diet for food allergies, it is not suitable for all dogs. Young growing animals or dogs with existing medical conditions such as pancreatitis should not be on the Anallergenic diet.
For growing dogs, the Royal Canin Hypoallergenic is a suitable option. Hills z/d prescription diet has no listed contraindications for other medical conditions like pancreatitis. It's always recommended to consult your veterinarian for the most appropriate diet for your pet.
What our customers say: "My dog developed a severe reaction to his food, our vet recommended Royal Canin Anallergenic and finally after months of issues, he is back to normal."
What our vets say: "Royal Canin Veterinary Anallergenic Dry Dog Food is the gold standard hypoallergenic diet for food allergies in dogs. Proteins are the most common triggers of food allergies, so hypoallergenic diets contain novel protein or hydrolysed protein as these are less likely to cause an allergic reaction, either because the dog hasn't been exposed to the protein source before (novel protein) or because the protein has been broken down into molecules that are so small, they are unlikely to trigger the immune system (hydrolysed protein). What makes Anallergenic unique is that it contains a highly novel protein source (feather protein) that is also hydrolysed, so even extremely allergic dogs or dogs that have been exposed to a wide range of protein sources are very unlikely to react to this food."- Dr. Michelle

It can be tricky to find a dry food that has no hidden nasties, so Open Farm is a breath of fresh air! Their ingredient list is so easy to review, and we can rest easy knowing the ingredients are transparent and consciously sourced. It was also great to have different protein choices and Grain free options for our pets sensitivities. I also loved the size of the biscuits. I was surprised to see a smaller biscuit size compared to the usual, larger sized ones for big dogs, however our staff really loved it! Also I just love that this is RSPCA approved and ethically made, just an added tick for an avid animal lover and environmentalist like myself. Amazing stuff, highly recommend!"

What to look for in a sensitive stomach dog food?
Diets designed for sensitive stomachs are easy to digest, often lower in fat and include prebiotics to aid digestion by promoting a healthy gut environment.
Formulated to support gut health
Look for diets which have been specially formulated for gut health and digestion, these are created by nutritionists and veterinarians based on years of scientific research. Such diets offer the best tailored nutrition, to provide optimal support for your pet and their digestive issues.
Suitable for your pet's individual needs
It is important to check with your veterinarian which diet is suitable for your pet's specific condition, whether they will need a prescription food for a medical condition. Specific digestive issues may require different therapeutic nutrition.
Safe proteins (for dogs with food sensitivities)
Dogs with suspected food allergies, requiring a food trial, are best placed on a hypoallergenic diet to confirm this condition - either a prescription hypoallergenic food (gold standard) or a novel protein diet as an alternative, this option may be suitable for pets who are more fussy with their food.
What are the Symptoms of a Sensitive Stomach in Dogs?
A sensitive stomach describes a pet who's digestion is easily upset. While every pet may experience an upset tummy from time to time, pets with sensitive tummies tend to be prone to repeated digestive upsets, which can present in a number of ways.
Some Common Symptoms include:
- Loose stool and diarrhoea
- Gas
- Lack of appetite
- Occasional vomiting
- Discoloured stool
Every dog's belly is different. Some pets with a sensitive stomach may experience 'on and off' bouts of chronic mild loose stools or gas, while other may experience less frequent but more severe instances with vomiting. Your pet may experience small bouts of tummy upsets in response to a rich treat and quickly improve, while others can become seriously unwell.
If gastrointestinal issues such as diarrhoea continue for an ongoing period, it is important to have your pet assessed by a veterinarian. Gastrointestinal issues can lead to weight loss, dehydration, and electrolyte depletion, especially in puppies.
When to see your veterinarian:
- Your dog is vomiting
- Your pet is a puppy
- Any loose stool persists for more than 2 days at a time
- The stool is watery
- The stool contains blood or mucous
- They are lethargic and off their food
What Causes a Sensitive Stomach in Dogs?
The Wrong Diet
A common cause of a sensitive stomach in pets can be poor nutrition. Poor quality, cheap diets are made from low quality ingredients and are harder to digest. This can lead to chronic digestive issues - particularly 'landmine' sloppy stools and excessive gas!
A sudden change in diet can be known to cause digestive upsets. Because of this reason, it is always a good idea to introduce a new diet to your pet slowly. Feeding your pet a Rotational Diet from a young age, can help prime their belly at a young age and decrease their sensitivity to diet change. Rotational diets may even be associated with a decrease in food allergies occurring later in life.

Parasites
Parasites such as intestinal worms and protozoa can be a causes of gastrointestinal issues in dogs. While most species usually cause acute symptoms - such as bloody stool, vomiting, or watery diarrhoea - there are some parasites which may cause general weight loss and ongoing mild gastrointestinal signs. To rule out parasites, always keep your pet's parasite prevention up to date and see your veterinarian if you are concerned.
Did you know that most all-in-one preventative products do not cover for tapeworms and an additional wormer is required. For more information on parasite prevention and to ensure your pet is covered for everything, see our veterinary written articles Flea, Tick and Worming Guide for Dogs.
Bacterial Contamination
Your dog may have a sensitive tummy secondary to an overgrowth of harmful bacteria in their gut. This can occur after an initial bout of food poisoning from eating something they shouldn't have, or from other 'bad habits' - such as hunting, eating dead animals or wild animal faeces.
Feeding a diet of raw meat or bones, can cause tummy upsets in some animals as well as posing a health risk to owners. A study by the FDA found that raw pet food can contain harmful bacteria such as Listeria and Salmonella which can spread from your pet to your family. This is a particularly dangerous for anyone immunosuppressed in the household such as pregnant women, children, or the elderly.
For more information on Raw Diets read our veterinary written article Should I Feed My Pet a Raw Diet?.
Antibiotic Treatment
A chronically sensitive stomach can sometimes occur after a course of antibiotics, particularly if your dog was treated early in life. Antibiotics, although necessary to treat infection, can disrupt the beneficial bacteria in the gastrointestinal tract, which can lead to digestive issues. The right balance of good bacteria in the gut plays an important role in digestive health.
During or after a course of antibiotics, a probiotic supplement can be beneficial to help boost your pets digestive health. Probiotic supplements are also a great addition for any dog that suffers from digestive issues.
For more information, see our veterinary written article: Probiotics for Dogs.
Food Sensitivities or Allergies
Much like their human owners, dogs can suffer from dietary sensitivities or food intolerances which can result in a sensitive stomach. Food intolerances in pets generally develop over time and can be associated with a range of common ingredients found in many commercially prepared pet foods including chicken, beef, egg, dairy and wheat.
If you suspect that your dog may have a food allergy or intolerance, a consult with your veterinarian is recommended. The veterinarian may recommend feeding a Veterinary Prescription Hypoallergenic Diet and doing an elimination trial to see if there is any improvement in your pets symptoms.
For more information on Hypoallergenic Diets, read our veterinary written article What is the best Hypoallergenic Dog Food?
Other Medical Conditions
Medical conditions of other organ systems may also cause your pet to suffer from chronic gastrointestinal issues. Particularly, pancreatitis, Inflammatory Bowel Disease (IBD), and disorders of the liver or adrenal glands can commonly be seen to cause gastrointestinal issues in dogs.
Often times if your dog has experienced a gastrointestinal issue in the past which resolved, they may forever be left with a sensitive tummy and never be able to tolerate rich foods or sudden changes to their diet. This is a common consequence of pancreatitis, which can leave dogs incredibly sensitive to fat.
