we have had Samson for 5 years, he is starting to nip, something he has never ever done before. He has nipped at me twice but with no teeth, he nips at his dog sister (again with no teeth that i call tell) but this one scares me because she is a pitbull and while I have NEVER seen our pitbull do anything against either of our yorkies (even when Samson was hanging off her lip one day and wouldnt let go while they were playing ball) it still makes me nervous. Yesterday Samson nipped at my oldest daughter and her son (my grandson) for the first time. I dont know why he is doing this. We have had him since he was 8 weeks old and again dont know why the change all of a sudden. I have never seen him nip at his younger yorkie brother. I am worried is going to be this cranky old yorkie. Suggestions??
