Oscar (AmBull)

Hi, I have a 9 week old AmStaff, who is currently on home made meatloaf, chicken necks, puppy milk and hills science. I too have found that he does not seem to want to eat the dry food at all. I am at the moment looking to slowly switch to RAW. Is RAW ok for puppies? Do you still mix in dry food with it? Any help on the subject of Puppy diet and RAW would be much appreciated. He is my first pup.
