Does your dog show symptoms of a sensitive stomach, such as vomiting, diarrhea, or a lack of appetite? These digestive issues can be distressing for both you and your furry friend. Managing a dog with a sensitive stomach requires careful attention to their diet and overall health.
Our medical team at Sploot Vets prepared this comprehensive guide to talk about how to determine if your dog has a sensitive stomach and the best dog food for sensitive stomachs.
I. How to Tell if a Dog Has a Sensitive Stomach
Dogs with sensitive stomachs display a variety of clinical signs or symptoms. These can include the following in varying severity and frequency:
- Vomiting
- Diarrhea or loose stools
- Flatulence
- Abdominal pain or discomfort
- Lack of appetite
- Weight loss in dogs
- Lethargy
Determining if your dog truly has a sensitive stomach involves a comprehensive assessment of their health and diet history by a veterinarian. They will need detailed information about all treats, chews, and supplements you give your dog.
Note: A veterinary consultation is crucial because symptoms of a sensitive stomach in dogs can sometimes indicate other medical conditions, such as endocrine diseases, autoimmune conditions, or exocrine pancreatic insufficiency, where the dog lacks essential digestive enzymes.

III. Dietary Change: Is it Necessary for Dogs with Sensitive Stomachs?
A certified veterinarian can determine if a dietary change is appropriate for your dog. Veterinarians may recommend prescription dog food, potentially through a 4-12 week food trial, or advise you on which ingredients to avoid moving forward.
Beyond dietary adjustments, your dog may also require additional products to support their digestive health, such as research-backed veterinary probiotics for dogs, like Purina’s FortiFlora.
IV. How to Choose the Best Dog Food for Sensitive Stomachs
Choosing the best dog food for sensitive stomachs involves certain factors, such as the protein source of the dog food, beneficial ingredients, ingredients to avoid, and the brand of the dog food.
A. The Best Protein Source for Dogs with Sensitive Stomachs
The protein source in dog food is crucial for dogs with sensitive stomachs. Preferred types of protein include:
- Novel proteins such as duck, venison, or fish, which are less likely to cause allergies.
- Single-source proteins to minimize the risk of an adverse reaction.
The key is to choose high-quality, easily digestible proteins that your dog has not been exposed to frequently.
B. Ingredients to Look for in Dog Food for Sensitive Stomachs
When choosing dog food for sensitive stomachs, look for the following ingredients:
- Easily digestible proteins such as chicken, turkey, or lamb.
- Limited ingredient diets (LIDs) to reduce the risk of triggering food sensitivities.
- Prebiotics and probiotics to support healthy digestion.
- Rice or oatmeal as easily digestible carbohydrate sources.
- Omega-3 and omega-6 fatty acids to help reduce inflammation.
C. Ingredients to Avoid for Dogs with Sensitive Stomachs
Certain ingredients can exacerbate a sensitive stomach and should generally be avoided:
- High fat content, which can lead to digestive upset.
- Artificial additives and preservatives like BHA, BHT, and ethoxyquin.
- Fillers such as corn, soy, and wheat can be harder to digest.
- Dairy products can be difficult for some dogs to digest.
Note: Grain-free formulas, which are often high in peas and lentils, are often marketed for dogs with sensitive stomachs. However, these can increase the risk of dilated cardiomyopathy (DCM) in otherwise healthy dogs.

IV. The Role of Probiotics & Prebiotics for Managing Your Dog’s Sensitive Stomach
Probiotics and prebiotics play a significant role in managing a dog's sensitive stomach. They help maintain a healthy balance of gut bacteria, which can improve digestion and reduce gastrointestinal issues.
Probiotics for dogs introduce beneficial bacteria, while prebiotics for dogs feed those beneficial bacteria. Including these in your dog's diet is highly recommended; some brands have these readily included.
V. Transitioning to Dog Food for Sensitive Stomachs
Sudden changes to a dog’s diet can lead to digestive upset. To transition your dog to a new food without causing digestive upset, follow these steps:
- Gradual Introduction: Mix the new food with the old food, gradually increasing the amount of new food over 7-10 days. However, Sploot Medical Director Dr. Marissa Sallee advises: “For dogs with a history of vomiting or severe adverse reactions to food changes, this transition period can be extended to 2 weeks or more.”
- Monitor for Reactions: Watch for any signs of digestive upset during the transition period.
- Patience: If your dog shows any adverse reactions, slow down the transition process.
- Probiotics: Dr. Sallee also mentioned that probiotic supplements can help reduce the likelihood of gastrointestinal issues while changing dog food.
