I understand, most pitbull owners don’t change their mind until blood has been spilled. I’ve seen it firsthand several times and these dogs were not being mistreated.

For other people, please look into dog breeds natural ability. Nurture will get you a well behaved dog but some have nature hardwired into them and it takes mountains of training to get it out of them. There are different breeds for a reason and it’s not just for looks. Just get the dog breed that fits your lifestyle.
