German Shepherd Vs Pitbul

People here talking shit like relax its a dog park to unleash your dog.And for those who talking shit about the owner he must be doing something right because i never saw the pitbull bite any dog at all. He even got next to the white dog and nothing happened.If that pitbull would of really been untrained he would of took the fight and fucked up that mutt that wasn't even full German Shepherd but no he got away from the fight and didn't escalated it and still kept going around in peace.
