Hi @KirbyHawk75 you will have to teach her to redirect her mouth onto a tug toy. If biting you is self-reinforcing, or you inadvertently reinforce it as a result of how you react, then it will not extinguish.
How and when is he bitting? Is it still like when he was a puppy? Constant bitting, pulling on pants,shirts....? My pup is 7 1/2 months and still bites. When he is playing and when he is cuddeling or happy/excited. But is not as bad as it was until he was 3 months.
