We have a 6 week old puppy chi with some what of an attitude problem. Whenever we try to pick him up he gets vicious. He has a bad anger problem he's never been abused. How do i go about getting him to not be vicious with myself and my family? I can't continue to have him biting. All he wants to do is play bite when hes down on the floor but if you pick him up he wants to viciously bite. How do i train him to not be vicious when we pick him up?
