Hi all -- I'm new to the site, not new to GSDs though 
I have a predicament with the newest member of the family. Jax is an 11 month old male, not fixed yet, that we adopted last week. It has become apparent that the poor guy has had minimal training. He is completely uninterested in my boyfriend and I (we co-own him) and is very nippy and jumpy. He does not have food aggression but nipped me when I gave him a treat and jumps and nips at my face when I am trying to work with him on a lead and he doesn't like something. We have a 14 month old fixed male boxer that we have had since 8 weeks and while Jax is playful, he will not let our boxer sniff him and he nips and jumps at his face and neck. Neither boy seems to want to give up dominance. Can anyone offer suggestions or help? I have had GSDs before nut have always gotten young pups that I trained and I have never had to deal with this in an 11 month old 75 lb and growing boy. I don't want anyone to get hurt. I need to be able to train him but he is not interested in me, he won't play fetch and he jumps whenever he wants something or cries and barks. It's been an exhausting week of little progress with him. He is housebroken and crate trained but hates the crate and paws and barks all night trying to get out.
