zoey has the same problem as bella. she would get all excited around other ppl. she would juz jump and bite playfully but she can get pretty rough at times. she's is not like that when she's with me coz she knows she's not suppose to bite. but some ppl allows her too bite their hands.that's why she thinks it's ok to bite other ppl.what can i do? i'm training her not to bite and at the same time other ppl allow her to do that
