Suzi is 7 months old and has A couple of Crazy puupy minutes a day.. I j ust figured that it because She is A terrier and A little puppy. that is really how they are, and just want to play.Suzi play bites, and alway pulls our pant legs and shkes them in her mouth . I think that it is cute when she does that. After playing hard she settles down and rests. These moments do not last , and i have put up with them.
