When we first gotten Tess she was on Nutro Ultra from the pet store that's when diarrhea begin then the Vet had us switch to IVet still diarrhea...poor girl then we tried Wellness for puppy still diarrhea but really bad it caused dehydration. So this we week we decided on Blue Buffalo for puppy and crossing the fingers. So far no diarrhea but she does poop a lot.

I def agree with @anatess regarding the food! Hope you find something that works...there is a sticky in the nutrition thread about diff foods that are recommended!
