Thanks again for all the great advice! There are several different situations in which he gets nippy and I find different things work in different situations. If he is playful and starts nipping at my hands then I say a loud, high-pitched "Ouch" and when he backs off I offer him my hand again and say "Kisses" and when he licks instead of nips he gets lots of praise! If he starts nipping at my feet and jumping at me like a maniac (when he's overly excited) then I grab a magazine or a book and block my feet while moving toward him saying "no", and he backs off every time. He has not nipped in response to me telling him to do something, or not to do something in a long time, so I really think we are making good progress. In response to that kind of nipping I did hold him on his back and say a firm "no". Sometimes I would have to do it 2 or 3 times (stubborn lil' thing
), but he always backed off if I was persistent.
