Switching Foods

Always transition gradually over 7-10 days. Mix 25% new food with 75% old food the first 2 days, increasing the new food percentage gradually. Sudden switches cause digestive upset.

FAQ

Q: What food is easiest on a dog's stomach?

A: Boiled chicken and white rice is the classic bland diet for upset stomachs. Long-term, Royal Canin Digestive Care or Hill's Science Diet Sensitive Stomach are the best commercial options.

Q: Should I feed my dog grain-free food for sensitive stomach?

A: Not necessarily. Grains are not inherently bad — some dogs actually digest them well. The FDA has flagged a potential link between grain-free diets and heart disease. Consult your vet before switching to grain-free.

Q: How long until I see improvement after switching food?

A: Allow 4-6 weeks for full dietary transition and assessment. Stool quality typically improves within 2-3 weeks.
