For those arguing that if they didn't own their dog, others would have the right to take their dogs for walks, tell them what to feed them, etc. What about children? Children don't have, and shouldn't have, all the rights of adults, and they do have some special rights adults don't have, based on their needs. Animals would be the same, rights geared towards their needs.
As for the idea that:
"And I don't buy that "companion/guardian" crap. Sorry...but if you derive any pleasure or satisfaction in owning and caring for (controlling) a domesticated animal, then you are no different than any other person who benefits in ANY way in the use or breeding of domesticated animals. You just happen to think your enjoyment and benefit is more altruistic than others."
So people who enjoy being parents, and caring for their children own them? My grandmother, who is caring for my grandfather at the end of his life owns him, because she controls the food, she controls his medications, she control the decision making, because he can't anymore. Ridiculous, they make these choices, to the best of their ability, based on the best interests of their loved ones, as they should. How are animal guardians any different?
