Probably more worrisome to me is taking for granted the way we've bred dogs to be gentle, calm, good-natured, etc. Most people don't do much to train their pet dogs or even learn to communicate with them. We more or less get away with that, societally, because dogs are insanely good-natured. Dogs give us so much 'for free'. I think without that, like when people just keep wolves as pets, I think things look a LOT dicier.
