Puppies learn from their mother and littermates how hard they can play. When they are taken from the litter as young as your pup was, they miss out on learning time. Puppies should never be taken that young. For yorkies and other small breed dogs, you shouldnt take them away until they're 10-12 weeks old. With that being said, they usually grow out of the biting stage. Can't really help you with the aggression, sorry. Also if you're crate training your new puppy, you dont want to put them there for a time out. Crates are supposed to be their safe place and when you use it for negative things, they will never like it.
