How long did it take for your puppy to stop biting aggressively?

It's all about attitude. If you feel her behavior is inappropriate and you are no longer going to put up with it, then let her know in no uncertain terms. She'll get it. Would you allow her to bite and draw blood every day? Of course not, you would find a way to get your message across. Each person has their own way of dealing with their dog depending upon the relationship that's been developed. How do dogs get each other to "listen"? They're very clear about the message they send.
