You can housetrain a dog. You can force a dog to take a bath. Dogs don't correct your stories. Middle-aged dogs don't feel the need to abandon you for a younger owner. Dogs don't mind if you do all the driving.
Dogs admit it when they're lost.
Dogs don't weigh down your purse with their stuff. Dogs look at your eyes. Dogs like your size. Dogs do not care whether you shave your legs. Dogs take care of their own needs.
