Abbey, I think, is part pit... A lot of people freak out when they hear the words "pit bull," but a lot of the problems that arise from the breed come from the people who train them to be aggressive and fight until death.
I'm sure you've seen some of the info about the dogs that came out of Michael Vick's dog fighting ring.. majority of them were actually re-homed and are "normal" dogs. They only had to put a couple of them down because they were too violent.
So I would say no, you don't need to be overly concerned with it. As long as you properly socialize and train your dog, you shouldn't have problems.
Ok that's pretty much how I feel as well. I just wasn't sure what other peoples take was too. We already have a few other people w/ dogs/puppies who he will be socializing with and the local pet shops offer "puppy socials" that he will be attending along w/ obedience classes in November.
Qualified no. Your puppy MAY become less tolerant, even aggressive of other dogs as she matures (18 mos - 2 yo). All the training and love isn't going to erase generations of selective breeding for inter-dog aggression. With good socialisation and a solid foundation of obedience, this shouldn't be a deal breaker, however. And some pitbulls are completely 'cold', and fine with other dogs for their whole lives.
Pitbulls are usually extremely social, stoic and deferent towards people.
The BAD rap website has some wonderful information on pitties.
