Nobody should own dogs. They were bred as slave animals in a time before we understood that they were just as sentient as any other being, with pain receptors and emotions just as real as our own. And we have bred them to be miserable when we are not there giving them attention. Their apparent affection is an illusion, a food-gathering instinct honed by countless generations of selective and cruel in-breeding directed by humans who want to pretend that these animals actually love them, when they're really just pretending because they are rewarded for it.

Also, if you own a dog and let it bark for any length of time, ever, or let it wander unrestrained where it might bite or harass a stranger, or let it take shits and don't immediately clean that up, you deserve to be put in a cage.
