He is 9 1/2 months old. Maybe I have overreacted. Butter is quite healthy. He has runny poo once in a while, but that can be traced to something else. He poos 3-4 times a day. The poo is grainy, and sometimes soft. My wife has reported he ate his own stool, but I has never seen him do it. He is now on the lean side with ~3 3/4 cups/day. I bought the current bag of Canidae ALS 40 lbs bag a week ago. I am not sure if I should switch to High protein food like Orijen, Innova which has similar ingredient but more expensive than Canidae, or just continue with Caniade.
