OH yes, I am aware you are sick of hearing about Hammie. BUT..he is STILL nipping me when I open the gate to the dog pen. I HATE THIS! I stand as close to the gate as possible....then I put my foot up..and he usually gets that in his face. BUT, still we go thru this everyday. He is on the whole, better...but he just HAS to do this nip. Now..it isn't aggressive in any way...BUT I STILL HATE IT!!!!!!!!!! I know I sound like a broken record........yes, I make him 'sit' prior to opening the gate....I yell...........cause I know he is going to do this 'nip' thingy. Please.........any more suggestions????
