- Avoid corn, wheat, soy, and powdered cellulose, these are common triggers.
- Transition foods over 7–10 days by mixing old and new kibble.

What causes a sensitive stomach and skin?
It's usually a reaction to protein or grain, not a single ingredient. Chicken and beef are the top offenders. Dogs can develop intolerances over time, so a food they ate for years might suddenly cause problems. If your dog has chronic loose stools, gas, or scratching, an elimination diet is the gold standard.
Ingredients to look for
Go for novel proteins like salmon, duck, or venison. Avoid chicken meal and beef meal. Carbs like brown rice can be irritating for some dogs, so sweet potato or oatmeal are safer bets. Added probiotics and omega-3 fatty acids (from fish oil) help digestion and skin health. If your dog has multiple allergies, you may want to compare products in the best dog food for allergies and sensitive stomach guide.

Homemade food: pros and cons
Homemade diets let you control every ingredient, but they must be balanced. A common mistake is feeding only meat and rice, which lacks essential nutrients. If you go homemade, work with a vet nutritionist. You can also mix homemade with a high-quality complete food. Learn more about the trade-offs in the dog food: home vs professional use article.
How to switch foods safely
Mix 25% new food with 75% old for 2–3 days, then 50/50 for 2–3 days, then 75/25, then 100% new. Go slower if your dog is extra sensitive. If your dog rejects the new food or has trouble, see our guide on how to troubleshoot common dog food issues.
