I feel totally uneducated in this area. Sunny came to us already on Science diet puppy chow so we've kept her on it but she became obsessed with canned food after stealing it from the cats so we added Nutro Max Puppy...just a forkful mixed in. BUT...I've been a nervous wreck about Nutro ever since I heard it might not be safe. Should I switch to something like Evo or Buffalo Blue...where do you get these foods? I guess I'll be googling tonight
