Sensitive Stomach Diet for Dogs: What to Feed

By Stacey Hunvald, DVM

Like people, some dogs have sensitive stomachs. It can be tricky to figure out exactly what is causing your pet's issue, but the right nutrition can help.

The term "sensitive stomach" is often used as a blanket statement to describe digestive issues of all sorts, no matter where in the digestive tract the issue is actually occurring. The digestive tract consists of the stomach, of course, but also the esophagus, small intestine, and large intestine, with assistance from the liver, gallbladder, and pancreas. The organs of the digestive tract are collectively called the gastrointestinal (GI) system. A dog with a sensitive stomach may be experiencing a health concern anywhere along the GI system.

While GI issues can be subtle and have symptoms that are similar to other issues occurring outside the GI tract, determining whether a GI cause is present and addressing the issue with diet and/or medications can have a big impact on your pet's overall health and comfort.

Signs of a sensitive stomach in dogs

Dogs with GI issues might experience the following symptoms:

• Vomiting, diarrhea, or both
• Poor appetite
• Difficulty maintaining weight
• Low energy
• Signs of pain, such as walking with a hunched posture.

Causes of GI issues

There are many possible underlying causes of GI issues in dogs, including:

• Food sensitivity or allergies to specific foods
• Inflammation in the intestines
• Illnesses elsewhere in the body that can cause digestive discomfort

While all pets can experience a bout of GI upset, if it happens more than occasionally, it should be discussed with your veterinarian. If GI upset is accompanied by an inability to keep down any food, unwillingness to eat, or lethargy, call your veterinarian as soon as possible, as these can indicate a serious illness.

A bloated stomach can indicate a critical emergency, so if you observe sudden severe discomfort and a large stomach, seek emergency care.

What to Feed a Dog With a Sensitive Stomach

If your dog is dealing with recurring vomiting, loose stools or general digestive upset, the right food can make a meaningful difference — but the best choice depends on why his stomach is sensitive in the first place. Here's how to think through the options, and when to loop in your veterinarian.

Sensitive Stomach Dog Foods: What to Look For

Most veterinary nutritionists point to a few key dietary features that can help support a calmer digestive tract https://wsava.org/global-guidelines/global-nutrition-guidelines/:

• Reduced fat content. High-fat meals slow gastric emptying and can worsen nausea, loose stools and, in some dogs, trigger more serious conditions like pancreatitis. A lower-fat sensitive stomach dry dog food is often a practical first step.
• Increased dietary fiber. Fiber regulates how quickly food moves through the digestive tract, supports nutrient absorption and feeds the beneficial bacteria living in your dog's gut https://sites.tufts.edu/petfoodology/. Both soluble fiber (which slows transit and firms stool) and insoluble fiber (which adds bulk) play a role — look for ingredients like beet pulp, pumpkin or chicory root on the label.
• High digestibility. Ingredients that are easier to break down put less stress on an already-irritated GI tract. Look for named, whole protein sources and avoid foods with a long list of hard-to-digest fillers https://www.aafco.org/consumers/understanding-pet-food/.
• Limited, recognizable ingredients. Fewer ingredients mean fewer potential irritants. A shorter ingredient list can also make it easier to identify what agrees — or disagrees — with your dog.

Food Intolerance vs. Food Allergy: Why the Difference Matters for Feeding

These two terms are often used interchangeably, but they're not the same thing — and the distinction shapes what you should feed.

Food allergies in dogs typically show up as itching or redness of the skin. Some dogs, however, develop a digestive intolerance to specific ingredients, resulting in GI signs such as vomiting or diarrhea https://www.merckvetmanual.com/management-and-nutrition/nutrition-small-animals/nutritional-requirements-of-small-animals. Left unaddressed, ongoing food intolerance and intestinal inflammation — sometimes called inflammatory bowel disease (IBD) — can lead to weight loss or nutritional deficiencies as the body struggles to absorb sufficient nutrients.

Specialized Diets Your Vet May Recommend

If your veterinarian suspects a food intolerance is contributing to your dog's GI signs, he or she may suggest a structured food trial using one of the following diet types. These are distinct from standard sensitive stomach formulas and are typically recommended and monitored by a vet:

Hydrolyzed protein diets These are veterinary diets in which the protein has been broken down into smaller molecules that the immune system often cannot recognize as an irritant. Because the protein is essentially "pre-digested," these diets can be useful when a true food allergy is suspected https://wsava.org/global-guidelines/global-nutrition-guidelines/.

Novel protein source diets These formulas use less common protein sources — such as rabbit, venison or duck — that your dog is unlikely to have encountered before. Because an allergic reaction requires prior exposure to the allergen, a protein your dog has never eaten is less likely to trigger a response. One important caveat: some novel protein foods still contain small amounts of more common proteins as secondary ingredients. Even a trace amount of an offending protein can provoke a reaction in a sensitized dog, so read labels carefully and ask your veterinarian before switching https://petnutritionalliance.org/.

Limited ingredient diets (LIDs) Limited ingredient diets are formulated with as few different ingredients as possible to reduce the number of potential irritants your dog is exposed to. They can be a useful tool for identifying whether food intolerance is driving GI concerns. One thing to know: there is currently no regulatory requirement for a pet food to meet a specific standard before it can be labeled a "limited ingredient diet" https://www.fda.gov/animal-veterinary/animal-foods-feeds/pet-food. That means the label alone isn't a guarantee of purity. Look for brands that conduct third-party testing, and always confirm ingredient lists with your veterinarian.

When Diet Alone Isn't Enough

Some GI inflammatory conditions respond well to dietary changes, but many have underlying causes — infections, parasites, motility disorders or IBD — that require more than a food swap. This is especially true when your dog is losing weight or showing signs of nutritional deficiency. Work with your veterinarian to rule out medical causes before assuming diet is the whole answer. He or she can help you choose the right dog food for your dog's specific situation and determine whether medication or other treatment is also needed.

A note on treats: Even the most carefully chosen sensitive stomach diet can be undermined by the wrong dog treats. During any food trial or diet change, keep treats to no more than 10% of your dog's daily caloric intake, and choose single-ingredient or limited ingredient options that align with his new diet.

What not to feed a dog with a sensitive stomach

Pet parents often ask what foods to feed dogs with sensitive stomachs. However, in many cases, the question of what not to feed your dog should also be considered.

While we always advise against feeding dogs high-fat human foods such as bacon, fatty pieces of meat, or poultry skin, this is particularly true for dogs with sensitive stomachs. High-fat foods may simply be too rich for your pup and also are thought to contribute to pancreatitis, a serious inflammatory condition of the pancreas.

Other table scraps can also be risky to a dog's GI tract. Some dogs do not tolerate certain vegetables due to the gases that often result from their digestion. Additionally, for some dogs, table scraps are simply too varied from their normal diet balance, resulting in stomach upset. Be especially aware of sources of unintentional table scraps such as from children dropping food or your pup sneaking bits from the counter or the trash.

Finally, you'll want to avoid excessive treats. Treats are intended to be just that, a treat. They do not contain balanced nutrition for your pup. Overfeeding treats may reduce your pup's desire to eat their more well-balanced dog food as well as directly cause stomach upset with excess fats or dyes or reduced digestibility compared to dog food. Remember, treats should make up no more than 10% of your dog's daily recommended calorie consumption.

Other digestive recommendations

Some dogs with mild sensitivities may see their symptoms improve with a change to a sensitive stomach dog food. Although they don't all follow the same rules about which ingredients to include or eliminate, they are formulated to balance protein, fat, and fiber to be more easily digested. As with any diet trial, you'll need at least two months of dedicated usage to determine its effectiveness.

For some dogs with digestive symptoms, probiotics can be helpful, fed either as a supplement or in a dog food that's been formulated to contain them. Probiotics are healthy bacteria that can aid digestion and help keep the intestines healthy and well balanced. They can have a positive impact on overall gut health, improving GI signs for several underlying causes. High-quality, dog-specific probiotics work best.

Fiber supplementation can also be helpful in addressing GI conditions, particularly in cases of diarrhea. Your veterinarian might recommend adding canned 100% pumpkin or a psyllium fiber supplement to your dog's feeding plan.

While one of these options could help alleviate your sensitive dog's digestive discomfort, remember that these changes should always be made in consultation with your veterinarian.

Finally, for dogs with sensitive stomachs, consistency is important. Feeding your dog on a regular schedule and sticking to a smaller variety of treats and foods can be helpful. One mistake some pet parents make is changing the diet too frequently to really assess a new diet's effect. Since GI issues can be frustrating, sometimes changing the food again in search of something that works better for your pup can be tempting. Remember that a new diet needs to be followed strictly for at least two months to determine its effectiveness. Of course, if your pup's condition worsens while on the trial, consult your veterinarian.

Diet changes for any reason should always be made slowly, but gradual transitions are even more important for sensitive stomachs. Mix small amounts of a new food into your pet's old food to start the process. Continue increasing the ratio of new food to the original diet over about 10 days.

Finding the right combination of diet and habits to keep your sensitive pup comfortable often requires some trial and error. But the positive changes to their comfort and overall health will be worth it to help them be their happiest, healthiest self!

Recommended Products for Dogs With Sensitive Stomachs

Finding the right food can feel overwhelming when your dog's stomach is easily upset — but a few key product categories consistently make a difference. The options below are organized by diet type so you can match the right solution to your dog's specific needs. Always loop in your veterinarian before making a significant diet change, especially if your dog's digestive symptoms are ongoing or severe.

What to Look for on the Label

Before browsing specific products, knowing what to look for helps you shop with confidence. The Association of American Feed Control Officials (AAFCO) sets the nutritional standards that dog foods must meet to be considered complete and balanced https://www.aafco.org/consumers/understanding-pet-food/. For a dog with a sensitive stomach, prioritize:

• A single animal protein source listed as the first ingredient
• Limited ingredient lists — fewer components mean fewer potential triggers
• No artificial colors, flavors or preservatives
• Easily digestible carbohydrates such as rice, oatmeal or sweet potato
• Added prebiotics or probiotics to help support a balanced gut environment https://sites.tufts.edu/petfoodology/
• An AAFCO nutritional adequacy statement confirming the food is complete and balanced for your dog's life stage https://www.aafco.org/consumers/understanding-pet-food/

Sensitive Stomach Dog Food by Diet Type

Note: Hydrolyzed protein diets are typically recommended and supervised by a veterinarian as part of a dietary elimination trial. Ask your vet whether this level of intervention is right for your dog.

Dry Food Options

Dry dog food formulated for sensitive stomachs typically features a shorter ingredient list, a named single protein (such as salmon or lamb), and a digestible carbohydrate base. Look for brands that include a prebiotic fiber source — such as chicory root or beet pulp — which can help support the growth of beneficial bacteria in your dog's gut https://sites.tufts.edu/petfoodology/. Dry food also tends to be more calorie-dense per cup, so portion control matters; follow the feeding guidelines on the bag and adjust based on your dog's weight and activity level.

Wet and Mixed-Feeding Options

Wet food can be easier for some dogs to digest because of its higher moisture content, which also helps support hydration. It works well as a standalone diet or mixed with dry food to improve palatability during a transition. When choosing a wet formula for a sensitive stomach, the same rules apply: short ingredient list, named single protein, no artificial additives. Explore the full range of dog food options — including wet, dry and mixed varieties — to find what works for your dog.

Treats for Dogs With Sensitive Stomachs

Treats count toward your dog's overall diet — and for a dog with a sensitive stomach, the wrong treat can undo the progress a carefully chosen food has made. Keep treats at or below 10% of your dog's total daily caloric intake https://wsava.org/global-guidelines/global-nutrition-guidelines/. When shopping for dog treats, look for:

• Single-ingredient treats (freeze-dried meat, plain sweet potato slices)
• Treats that match the protein in your dog's main diet — if your dog eats a salmon-based LID food, a chicken-based treat could reintroduce a trigger
• No artificial flavors, colors or sweeteners — xylitol in particular is toxic to dogs https://www.aspca.org/pet-care/animal-poison-control
• Small size or easy-to-break pieces so you can keep portions modest during training

A Note on Supplements

Some pet parents add a probiotic or digestive enzyme supplement to their dog's routine to help support gut health alongside a sensitive stomach diet. While these products can be a useful complement, they are not a substitute for an appropriate base diet — and their use is best discussed with your veterinarian, particularly if your dog has an underlying gastrointestinal condition https://www.merckvetmanual.com/management-and-nutrition/nutrition-small-animals/nutritional-requirements-of-small-animals.

Not sure where to start? A Petco-knowledgeable nutrition associate can help you compare options in store, or you can use the filters on the dog food page to narrow by diet type, protein source and life stage. When in doubt, bring your dog's symptom history to your veterinarian — he or she can help determine whether a dietary change alone is enough or whether further evaluation is needed.

Frequently Asked Questions

What ingredients are best for a dog with a sensitive stomach? Look for foods with a single, easily digestible protein source (such as chicken, salmon or lamb), a modest fat content, and added fiber from sources like beet pulp or pumpkin. Limited ingredient diets reduce the number of potential irritants your dog is exposed to at once. Your veterinarian can help you match the right formula to your dog's specific GI concern. https://www.merckvetmanual.com/management-and-nutrition/nutrition-small-animals/nutritional-requirements-of-small-animals

How long does it take to see improvement on a sensitive stomach diet? Give any new diet at least eight weeks — roughly two full months — before drawing conclusions. The GI tract needs time to adjust, inflammation needs time to calm, and subtle improvements in stool quality or energy can take several weeks to become obvious. Switching foods again before that window closes is one of the most common reasons a diet trial fails. https://sites.tufts.edu/petfoodology/

When should I switch my dog's food, and how do I do it safely? Switch only when your veterinarian recommends it or when a current food is clearly not working after a full trial period. Always transition gradually: mix roughly 25% new food with 75% current food for a few days, then move to 50/50, then 75% new, then 100% new over 7–10 days. A slow transition gives the gut microbiome time to adapt and reduces the risk of additional upset. https://wsava.org/global-guidelines/global-nutrition-guidelines/

Are limited ingredient diets regulated differently from regular dog food? No — and that matters. There is currently no regulatory requirement that defines or enforces the term "limited ingredient diet" on a pet food label, meaning manufacturers can use it without meeting a specific ingredient-count standard. Always read the full ingredient list and look for an AAFCO nutritional adequacy statement to confirm the food meets minimum nutritional requirements for your dog's life stage. https://www.aafco.org/consumers/understanding-pet-food/ https://www.fda.gov/animal-veterinary/animal-foods-feeds/pet-food

Can probiotics actually help a dog with a sensitive stomach? Probiotics can support a balanced gut microbiome and may help reduce GI signs for several underlying causes, including mild inflammation and diarrhea. Choose a dog-specific probiotic product rather than a human formulation, since the bacterial strains most beneficial to dogs differ from those studied in people. Ask your veterinarian which strain and dose is appropriate before adding a supplement to your dog's routine. https://petnutritionalliance.org/

When is a sensitive stomach an emergency? Contact your veterinarian promptly if your dog cannot keep any food or water down, refuses to eat, or seems lethargic alongside GI symptoms. A suddenly bloated, hard abdomen paired with signs of severe distress is a potential emergency requiring immediate veterinary care. When in doubt, call your veterinary clinic or an emergency animal hospital right away.

Sensitive Stomach Dog Food Types: How They Compare

Choosing the right food for a dog with a sensitive stomach can feel overwhelming. This table breaks down the most common diet approaches — what they are, who they're best suited for, and what to keep in mind before switching.

A note on diet trials: Regardless of which diet type your veterinarian recommends, allow a minimum of eight weeks of consistent feeding before evaluating results. Switching foods too frequently is one of the most common reasons a diet trial fails to give useful information. Transition slowly — mixing increasing amounts of the new food with the old over seven to ten days — to avoid adding transition-related GI upset on top of the underlying issue.

Frequently Asked Questions

What is the best food to feed a dog with a sensitive stomach? There is no single answer — the right food depends on the underlying cause of your dog's GI signs. Mild cases may respond well to a commercially available sensitive stomach formula with moderate fat and added fiber. Dogs with suspected food intolerance may need a limited ingredient or novel protein diet, while those with confirmed GI disease often require a prescription therapeutic diet. Work with your veterinarian to match the diet type to your dog's specific situation https://wsava.org/global-guidelines/global-nutrition-guidelines/.

How do I know if my dog's stomach issues are caused by his food? Food intolerance typically shows up as recurring vomiting, diarrhea, or both — sometimes alongside skin itching or redness. Your veterinarian may recommend a strict diet trial (usually eight to twelve weeks) using a hydrolyzed protein or limited ingredient diet to determine whether food is the trigger. Keep in mind that GI signs can also stem from causes unrelated to diet, so a veterinary exam is an important first step https://www.merckvetmanual.com/management-and-nutrition/nutrition-small-animals/nutritional-requirements-of-small-animals.

Are limited ingredient diets regulated by the FDA or AAFCO? AAFCO establishes nutrient profiles and ingredient definitions that most US pet food manufacturers follow, and the FDA oversees pet food safety broadly — but neither agency currently regulates the marketing term "limited ingredient diet." That means any brand can use the label without meeting a defined standard. Always read the full ingredient list and look for an AAFCO nutritional adequacy statement on the package https://www.aafco.org/consumers/understanding-pet-food/ https://www.fda.gov/animal-veterinary/animal-foods-feeds/pet-food.

Can probiotics help a dog with a sensitive stomach? Probiotics — beneficial bacteria that support a balanced gut microbiome — can be a helpful addition for some dogs experiencing GI signs. They are available as standalone supplements or incorporated into certain dog foods. Dog-specific probiotic strains tend to be most effective. Probiotics are generally considered supportive rather than a standalone treatment, so discuss their use with your veterinarian, especially if your dog's symptoms are persistent or severe https://sites.tufts.edu/petfoodology/.

How many treats can I give my dog if he has a sensitive stomach? Treats should make up no more than 10% of your dog's total daily calorie intake — and for dogs with sensitive stomachs, keeping treat variety low and fat content minimal is especially important. High-fat treats, table scraps, and foods with artificial dyes or low digestibility can directly trigger GI upset, even in small amounts. Stick to simple, single-ingredient treats and factor them into your dog's daily feeding plan https://petnutritionalliance.org/.

When should I call my veterinarian about my dog's stomach issues? Contact your veterinarian if GI symptoms occur more than occasionally, if your dog is unable to keep any food down, is refusing to eat, or seems lethargic. A bloated or distended abdomen accompanied by sudden severe discomfort is a potential emergency — seek urgent veterinary care immediately. Persistent vomiting or diarrhea can lead to dehydration and nutritional deficiencies, so early intervention matters https://www.merckvetmanual.com/management-and-nutrition/nutrition-small-animals/nutritional-requirements-of-small-animals.
