It is the irresponsible breeding for aggression that has caused so many problem involving Pit Bulls. While some will argue that Pits need to have owners that know how to handle them responsibly it is also being bred deeper into their lines. Just like a responsible breeder looks for certain characteristic and genetics irresponsible breeders that look to use Pits for aggression or worse yet dog fighting breed for these traits. From my understanding, when dogs are bred for fighting they consider things like the strength of their jaws, jumping ability, aggressive nature when they are paired together for breeding. Its much like breeding as a champion on the grayhound track or horse track. If you want to win then you take the best and go from there. I have heard very reputable members of YT refer to needing to know many generations back and how a recessive gene can come through with a breeding. If you take this theory and apply it to irresponsible breeding for this purpose what you get is dogs that are attacking and KILLING people. IMO there really is no argument for this because it is genetic and you cannot control genetics with behavior modifications.
