Eugenics gave us much better cows, pigs and chickens. We've continued that to freakish levels in some instances. You morals are your own; mine are just fine with short lived chickens and $2/lb chicken breast.

The angus and longhorn enthusiasts better police some of their nuts or they're gonna get the Aurochs back.

The purpose of dog breeding isn't health or usefulness, it's to match a picture and description.

Generalizations like this are kind of ridiculous, given the existence of hunting dogs, police dogs, herding dogs, livestock guardian dogs, and even many ordinary family/companionship dogs that are specifically bred to be docile, long-living pets.

Dogs are not naturally occurring.
