rem700,
How does it hurt to have the pup in your girlfriends arms? The only problem it will cause is the pup will listen to her and not you because you haven't bonded with it. Dogs are pack animals and need socialization. Without it, he won't do anything you ask. He'll be a nervous, sociopath. Dogs need attention, not just training. Pick him up and pet him. I promise it won't hurt him a bit and probalby help your relationship. Even macho guys can do this, promise.
