Yes, the vet did a bunch of tests on him, they have no idea whats wrong with him.

He had been going to the vets every day for the past two weeks (basically since we got him!) and we finally decided to stop bringing him because it seems like all they were doing was monitoring him. The change in food that we made, got him more lively than what they were doing so we decided to keep him at home and not at the vets anymore.
He's going onto 11 weeks now. I guess we figured he'd be able to eat the dry food since the breeder said he was eating dry food from them. I'm just wondering if there's something else that will help with his diarrhea. We'll keep with the chicken and rice since he loves it and is more excited to eat, but has anyone else had issues with this food giving their pups diarrhea?
