What Causes Sensitive Stomachs in Dogs?
Sensitive stomachs can stem from several causes:
- Food intolerances — Difficulty digesting certain ingredients (different from true allergies)
- Rapid food changes — Switching foods too quickly disrupts gut bacteria
- Low-quality ingredients — Hard-to-digest fillers and artificial additives
- Underlying conditions — IBD, pancreatitis, or other medical issues requiring veterinary care
If symptoms persist beyond 2-3 weeks on a new food, or if you notice blood in stool, severe lethargy, or weight loss, consult your veterinarian immediately. For more on distinguishing food intolerances from allergies, see our guide on food allergies vs. intolerances.

How to Transition to a New Food
Never switch foods abruptly — this alone can cause digestive upset. Follow this gradual transition schedule:
| Days | Old Food | New Food |
|---|---|---|
| 1-2 | 75% | 25% |
| 3-4 | 50% | 50% |
| 5-6 | 25% | 75% |
| 7+ | 0% | 100% |
For dogs with very sensitive stomachs, extend this to 10-14 days. For detailed guidance, see our complete food transition guide.
How Much to Feed
Feeding amounts depend on your dog's weight, age, and activity level. Use our feeding calculator to determine the right portion size, then adjust based on your dog's response.
General guidelines for sensitive stomachs:
- Feed smaller, more frequent meals (2-3 times daily vs. once)
- Avoid feeding immediately before or after exercise
- Keep meal times consistent
- Avoid table scraps and sudden treats
When to See a Veterinarian
Seek veterinary care if your dog experiences:
- Vomiting or diarrhea lasting more than 48 hours
- Blood in vomit or stool
- Significant weight loss
- Lethargy or weakness
- Loss of appetite for more than 24 hours
- Abdominal pain or bloating
These symptoms may indicate conditions like pancreatitis, inflammatory bowel disease, or parasites that require medical treatment beyond a diet change.
Frequently Asked Questions
Is grain-free food better for sensitive stomachs?
Not necessarily. Despite marketing claims, there's no evidence that grain-free diets are easier to digest for most dogs. In fact, some grain-free foods are higher in legumes, which can cause gas. Rice and oatmeal are highly digestible grains often used in sensitive stomach formulas. For more on this topic, see our article on the grain-free debate.
How long does it take to see improvement?
Most dogs show improvement within 2-4 weeks on an appropriate diet. If you don't see progress after 4-6 weeks of consistent feeding (with no treats or table scraps), the food may not be right for your dog, or there may be an underlying medical issue.
Should I add probiotics separately?
Many sensitive stomach formulas already contain probiotics. Adding more isn't harmful but may be unnecessary. If your current food doesn't contain probiotics and your vet recommends them, a canine-specific probiotic supplement can help.
What protein is easiest to digest?
Chicken and fish are generally considered highly digestible. However, chicken is also a common allergen — if your dog has a sensitivity to chicken specifically, novel proteins like duck, venison, or lamb may work better despite being slightly less digestible on average.
Can puppies eat sensitive stomach food?
Some sensitive stomach formulas are labeled "all life stages" and are appropriate for puppies. However, many are adult-only. Always check the AAFCO statement on the package. Puppies have higher nutritional requirements, so a puppy-specific sensitive formula is ideal. Browse our puppy food options.
