The thing is, I think it can go both ways. I don't always think it's a lack of ethics that gets a breed into trouble. I think it can simply be a lack of foresight. Sometimes when you breed for one trait, you accidentally lose traits that seem unrelated. I think there is also a natural tendency in competition to reward increasingly extreme expressions of a trait. I think that's how the "budweiser" dog ended up with that incredible curvature in the muzzle.

For instance, the bulldog standard explicitly stated that the dog should have a "massive" head. It was only after major negative publicity that this requirement was changed.
