This is another point. If you breed good genetics into good genetics, that is how all purebred dogs come about. Likewise, breeds with bad hips or other congenital problems also arise from these breeding practices.

Humans are the same way. As I've suggested, cousin marriage, by necessity, was very common until the Industrial Revolution. It is most prominently (and infamously) known among royal families back to the beginning of recorded history. Recent examples include the "Hapsburg Jaw" (typified by Charles II whose family tree largely did not, for the lack of a better term, "fork") and hemophilia throughout many royal bloodlines of Europe just in the past couple of centuries (primarily 2 of Queen Victoria's daughters carrying the mutated gene).
