how breeding affects the dog

Having raised some pits myself and researching of the breed has lead me to a conclusion that most advocates of the breed might disagree with. I believe that the only way to salvage the breed is to euthanize a big majority of the dogs that are out there now. My opinion might not sound all that "friendly" but I believe it is something that needs to be done and I will explain why. The majority of dogs that are out now do not reflect the dogs of yesterday that made the breed what it once was. Bearing in mind that this is not true of all dogs, it would be a massive undertaking that would require much more than the average "temperament tests" could sort out. This would require that all dogs bred for fighting be put down to remove the temperament that so called dog breeders have mistaken for that which makes a great fighter, namely agression to other dogs and people. In the hayday of the old "dog men," dogs were carefully chosen, or "selected" for breeding only when a strict set of standards was met by the dog after full maturity, the only age range at which the dogs true nature can be determined. Also, of course, the dog had to be a good fighter. This, however didn't necessarily mean that the dog would be continually fought until death. Some dogs were only "game tested", displaying their gameness as well as intelligence, stamina and the dogs attitude toward the handlers in the "pit".
These traits, among a wealth of others, is what makes a great pit bull. Todays "breeders" (those who seek to breed a fighting dog), for the most part, do not have the knowledge, experience, or the desire to breed to a standard that would require them to destroy half the litters for the first few generations, not because they are dog lovers, but because this would either cut into or cut out their profits from the sale of puppies. Destroying dogs that don't meet the standard, however, is something that must be done now to produce consistent results in future generations and in effect produce a dog that is stable in all aspects. There is an old saying among breeders of sporting dogs "if you can't drown a dog you don't need to breed them", it may sound cruel to the breeding heart liberals among us but natural selection is no longer present in the breeding of domesticated animals, so it is up to us to do it. Any dog that shows aggression to people should be immediately put down, no matter how "sweet" he has been in the past, this behavior will only be passed down to the next generation and perpetuate the aggression. Training and humane treatment of the dog do have alot to do with the dogs behavior, but not near as much as breeding. As an example, I had a german shepherd who would go to the cow pasture across the road every day at the same times to round them up, keep them together, and lead them to feeding. We never taught her to do this, it had been bred in from the beginning and that standard maintained throughout the generations to produce a consistent results.
