The dogs in our lives, the dogs we come to love and who (we fervently believe) love us in return, offer more than fidelity, consolation, and companionship. They offer comedy, irony, wit, and a wealth of anecdotes, the "shaggy dog stories" and "stupid pet tricks" that are commonplace pleasures of life. They offer, if we are wise enough or simple enough to take it, a model for what it means to give your heart with little thought of return.
