We have a 10 week old shepherd mix puppy. We have only had her about a week. We also have a 5 year old shepherd/doberman (THE BEST DOG). The new puppy, plays fine - does her normal puppy biting and play growling. But if the puppy is doing something she shouldn't or laying down and my daughter tries to pick her up she growls and then turns back to bite her. Yes, I know my daughter shouldn't be picking her up when she is laying down BUT I can do it just fine, I can pick her up from a deep sleep and she doesn't do anything. Is there something I should be doing to nip this in the butt now, before she is big and does some real damage?
