A study conducted by the State University of New York at Buffalo Medical School suggested that in times of stress a dog is likely to be more help in calming you down than a spouse or partner. Most dog owners can guess the reason why: dogs never judge us and never compete with us.

The dog becomes the repository of those model human properties that we have cynically ceased to find among humans. Where today can we find the full panoply of William Bennett's Book of Virtues-from Courage and Responsibility to Loyalty and Family Values-but in Lassie and Beethoven and Millie and Checkers and Spot?

Dog love is not the special realm of childhood or of boyhood, no matter what the movies keep telling us. It is highly significant, I think, that at both ends of human life span the bond between human and dog speaks with an insistent clarity - if we have the ears to hear.

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. Both powerfully imaginary and comfortingly real, dogs act as mirrors for our own beliefs about what would constitute a truly humane society. Perhaps it is not too late for them to teach us some new tricks.

If any era should be aware of the temptations to rewrite history, it is our own.
