IAMS does not use quality ingredients in their food. This also includes Eukanuba, ANY Purina Products (including Pro Plan), Science Diet, Ol Roy, Puppy Chow, Beneful, etc. ANY animal by-products = bad, and I do not recommend you feeding ANY pet ANY food containing ANY animal by-products, at all.

Anyway, did you properly switch foods?? You are supposed to mix the new food with the old and gradually increase the amount of new food until there is no old food left so your pup's body can adjust to the change. They may have soft or runny stools for a week or so while their body adjusts. This is common but can be avoided by properly introducing new foods
