I am going through this with my guy! He doesn't push but he is very nippy!
I am currently bopping his nose or mouth when he does it and telling him no biting! Not hard or anything, just a small bop! So far, it is not working! LOL But I hope it will in time!
I just got him gelded so I am hoping this will help with the nipping too! I heard that males tend to get a lot nicer once their testosterone is all gone!
Sorry, I probably wasn't much help!
Oh, on a side note! He actually started to lick my arm one time, so I am currently trying to reward him for that and saying "kisses, good boy". I am hoping that his nipping will turn into kisses!!
