My puppy is 10 week so old and raw fed. I’ve seen various dehydrated treats such as chicken feet/tracheas etc but not sure whether he is old enough for these. I’m wondering what I can give him in his crate while I nip out to keep him occupied. He has a kong but he doesnt bother with it and I’m not sure about leaving raw bones in the crate (plus last time he had a duck wing he tried to swallow the whole thing in one).
