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.
One of the greatest gifts we receive from dogs is the tenderness they evoke in us. The disappointments of life, the injustices, the battering events that are beyond our control, and the betrayals we endure, from those we befriended and loved, can make us cynical and turn our hearts into flint – on which only the matches of anger and bitterness can be struck into flame. By their delight in being with us, the reliable sunniness of their disposition, the joy they bring to playtime, the curiosity with which they embrace each new experience, dogs can melt cynicism,and sweeten the bitter heart.
She'd been acutely aware that terror, betrayal, and cruelty had a human face, but she had not sufficiently appreciated that courage, kindness, and love had a human face as well.
