Max is a good pup. first time he's ever snapped at anything was a month or so back. i took him out so my sister could see him and while he was sitting on me another small dog came over and put it's paws on my leg so it could get a good look at Max, promptly got nipped on the nose. Max is 13 and that is the first time he's ever been aggressive, he's not a yapper - only barks when someone is at the front door
