There are those exceptions and it can depend on the individual dog, but as a general rule to live by with Pits, they can't always be trusted with other dogs. Sure if you raise them with other dogs, they are less likely to be as dog aggressive as a closely game bred dog or a dog that has been used for fighting or just encouraged to be aggressive, but like the "point" in a Pointer or the "herding" in a Border Collie, you can't raise it or socialize it out of them. It's their nature that's been bred into them for hundreds of years. I have a pair of rescued Pit pups that I hand raised from birth with each other and around other dogs. They did great at first, but the runt started fighting with the other fosters dogs at about 4 months old and when he would get into a fight, his brother would join in to stand up for him. These weren't just little puppy play fights either, these were full blown fights that drew blood. The pups are now 9 months old and sometimes get into fights with each other. Like I said, there are those exceptions, but with Pits, you have to be careful and know that they have potential for animal aggression and they definately have the ability to fight like a pro if the occasion arises. Even if the Pit doesn't start the fight, they will finish it and get the blame in the public's eyes.
