Not that I'd want to hurt an animal, but it really makes no sense. If you breed and coop an animal up in an abusive, poop-drenched enviornment with the intent of killing it and selling the corpse for eating, it's completely ethical. But yelling at a dog is evil. Animals that we test shampoos on get treatment a hundred times better than farm animals. Really, their life sucks. And no one cares, 'cause they taste good. The amount of vegetarians and vegans don't hardly make a dent. So why can't other animals be treated just as poorly?
I like animals, but seriously this makes NO sense.
