No matter how close we are to another person few human relationships are as free from strife disagreement and frustration as is the relationship you have with a good dog. Few human beings give of themselves to another as a dog gives of itself. I also suspect that we cherish dogs because their unblemished souls make us wish - consciously or unconsciously - that we were as innocent as they are and make us yearn for a place where innocence is universal and where the meanness the betrayals and the cruelties of this world are unknown.
