That brings us back to one of the reasons you don't want to alter traits of dogs. You may think you're making the same dog without the dog aggression but you're significantly changing the genetic make-up of the dog. You'll end up altering/losing more than just the dog aggression. The traits go hand-in-hand. I'm sure the breeders get driven dogs every once in a while but I'm willing to bet that their dogs are just watered down AmBullies. They're no longer APBTs when you try to change what made this dog what it is today.
