>>343703As far as I'm concerned, if a sport is happy, healthy, and able to function with its deformities, then there is utterly no reason to kill it. It may even be of use as a therapy animal ("I lost my leg in a car accident but this dog can walk on two legs...maybe my life isn't over after all"). If, on the other hand, the animal is extremely ill or is in a massive amount of pain and discomfort or can't feed itself, then of course it should be euthanased. And deliberately breeding deformities into a breed (i.e Munchkins- people should be SHOT) is of course a big fucking wank.
