Pit Bulls Were Never "Nanny Dogs". Never. It's A Myth

39. And that is just completely wrong.

Even Cesear Milan notes in his books that some dogs are just "bred wrong" and have problems no amount of training and socialization can overcome. It was rampant in the American Cocker Spaniel at one point, so much so that people quit buying the little dogs, because, quite frankly, they sucked. Mean little biters with aggression problems and an overabundance of fear biting, all brought about by indiscriminate breeding. 20 years earlier, hunters had them and most of them were black. When they became the designer dog and breeders started inbreeding and doing all sorts of weirdness to get other colors, the cesspool ensued.

Dogs need sound genetics and then good training. As long as pit bull breeders continue to do "their thing", you are going to end up with a fair amount of screwed up dogs in the breed.
