My dog is a 6 year old 95 pound boxer, and he is just INSANE, and Im not even kidding, around other dogs. He's perfectly calm at home but when he sees another dog he can't control himself. If he's on a leash he'll pull your arm off or get out of his collar and charge at the other dog. Im pretty sure he doesn't mean any harm because he's gentle, but the problem is that I have a new neighbor moving in next week with a 5 year old rottweiler who is a rescue with behavior problems. What am I supposed to do? I don't want there to be a fight...
