Ultimately, your car keys are much more interesting to a dog than the vehicle itself. Dogs never choose music or lifestyles you find objectionable. They seldom fall in with bad company or experiment with drugs. They cannot name even one Heavy Metal band. If you give them a radio, they just lick the knobs - quietly.
Dogs are cleaner.
Sure, they lick their butts, but they lick their butts directly . Watch a five year old s hands for an hour - you ll be too nauseated to reach for the disinfectant. That said , it must be admitted that we live in an unfair world where dog parents are denied the common courtesies those with human puppies enjoy. My husband was clever enough to spot this disturbing inequity on one of our vacations. Parents of human children never need to leave their kids in the car when they stop at a restaurant.
