Of that I'm certain. Think about it. There is much in a dog's guileless existence that we could learn from. I made a short list. Dogs enjoy the simple life.
Dogs eat, sleep, eat some more.
They bark at perceived danger or just for the fun of it. They salute a full moon. They never balance a checkbook, expect a raise, plan a seating arrangement for a dinner party. Dogs obey nature. They come when they hear a voice that's near enough to matter.
