No with certain breeds, it's the dog. I fully respect that someone can own a pits all their lives and have no incidents. The same way someopne can smoke all theri lives and never get cancer. I understand that if a pit grows up with a loving home it's less likely to attack. However that likelyhood never leaves completely. And like I said the biggest problem with pits is the damage they can do the second they decide to attack. Their mouths are designed to kill. The selective breeding that's brought them to where they now are mean they have the stronngest jaw strength of any dog. They're very dangerous whether people accept it or not.
