I dont have a problem with this. I keep hearing about how people can't train dogs, how dogs "misbehave," etc.

Oh course they have issues, pets aren't designed to live domestic suburban human lives. I just don't believe humanity automatically and morally should have dominion of all animals. I think giving up on non-working pet ownership is a step in the right direction. And when sci-fi style robotics gets here, give up on working animals altogether.

I say this as someone who loves and has owned several dogs. They're just not cut out for our lives. I think there was a study that showed most pets have severe mental illness. Not to mention, the ones that can't play the human domestic game and heaven forbid show their natural aggression or dominance traits, well they get killed. How the hell is this moral? Why is the loss of pet ownership this horrific thing? It seems like thats the way a compassionate society should be leaning towards.

You already cannot have pets if you treat them cruelly. At least in theory.

Animals don't have rights. The property-owning rights of humans are restricted when the property in question is an animal.

For the most part, these additional restrictions are to prevent animal owners from practicing monstrous acts on the animal. Failure to abide by those restrictions is a social signal that the human may not be able to behave in a civilized fashion with other humans. The restrictions have the outward appearance of protecting animals from cruelty, but the actual intent is for civilization to identify and protect itself against cruel humans.

Animal rights advocates have lost the plot. Certain interactions, like the exchange of rights, can only appear between equals. With the possible exception of animals like the great apes, corvids, pachyderms, and cetaceans, the vast majority of species are strictly inferior to Homo sapiens with its awesome powers of language, social coordination, and tool use.
