As you can see I have a pitbull named tank. He was a rescue and couldn't be any sweeter. He has never bitten anyone or any dog. He has no food aggression, no possessive aggression behavior and is great with dogs of all sizes. I wouldn't bring another dog into my home if i didn't think tank could handle it. In fact, he is a therapy dog. I regularly take him to children's hospitals and nursing homes. He is gentle and puts a smile on everyones faces.
