I don't have a "problem" necessarily with DA in APBTs either, being as they are terriers first and foremost, and were created to be a fighting breed on top of that. Unfortunately, the ratio of people who can handle true DA to APBT/mix dogs out there is just too small. I honestly don't have an answer for what the best solution is to that "problem," in the real world; In a perfect world, it could be as simple as magically making every breeder thoroughly screen homes, every owner would be perfectly honest with said breeders about their level of experience and commitment to their dogs, and nobody on either side would make mistakes. In other peoples' perfect world, we'd just magically breed the DA out of the APBT while keeping every other aspect of the breed intact, because DA has no "place" in the majority of modern society.
But it's not a perfect world.
It's easy for people to say, "just breed the DA out." I agree that DA in and of itself doesn't have much of a place in modern society. But "just breed the DA out, problem solved" is about as logical as the common solution to the overpopulation problem, "just stop ALL breeding for 15 years." In both cases, yes, it's a no-brainer solution on paper (and that whole "perfect world" thing in which everyone intended to comply actually does so), but the problem is that people rarely consider the negative ramifications of what they're suggesting. In the case of "just stop breeding," well, dogs would go extinct. "Just breed the DA out?" At this point, it would be extremely difficult to breed out true DA in APBTs without unintentionally breeding out the drive and intensity that makes the APBT such a great and versatile working breed.
So, I don't have a solution. My "solution" for right now is to try to make APBT owners understand that there is no level of training or management that will always prevent a dog fight, without fail, if they run an APBT with another dog. Sure, that makes me sound like an a.sshole, but what else is there? After repeating the same thing over and over for decades and seeing...and cleaning up...the damage done when people don't want to believe it. What else is there?
