dog吧. if you get one of these that can have a divider put in, then you just need 1 - I had a smaller crate for d2 and got a bigger one later. feed whatever breeder is using for now, then mix in with new food. don't just switch to new food - puppy will have upset stomach. As to brands, check the links a few posts above - those are good links. Remember to buy puppy food and not adult food and don't overfeed. read the back of the label. fewer ingredients the better. I like happy hip and so doe
