Does Harley only bite Donovon or does he bite other children also? I have only had a problem wiith Chachi biting once and it was me and he tried to bite My Husband and My Husband put him on his back and yelled at him no bite and he didnt do it again. I dont know what I would have done if it continued. Have you spoken to a trainer about this? Good luck I know you are frustrated and i hope you can get to he bottom of why he is doing that |
