This is my sister dog that I watched for a few weeks. He is a big kind hearted thug who will knock into anything, knock anything over or rub up against things without seeming to feel them. I swear sometimes he has no nerves in his skin. He loves to play, loves to wrestle and play rough, and never tires. This dog is a strong lump of almost unmovable muscle and as stubborn as the day is long in summer.
