Dogs don't feel threatened by your intelligence. No dog ever voted to confirm Clarence Thomas. You can house train a dog. Dogs are easy to buy for. Dogs are good with kids.
Dogs are already in touch with their inner puppies.
You are never suspicious of your dog's dreams. Gorgeous dogs don't know they're gorgeous. The worst social disease you can get from dogs is fleas. Dogs don't need therapy to undo their bad socialisation. Dogs don't make a practice of killing their own species.
