It's the heart and spirit of the dog, revealed in hundreds of beautifully composed portraits in black-and-white and color. A pair of matching boxers in matching red sweaters. The melancholy gaze of a Pug. A stately Doberman in profile, a colorful trio of setters, a Lab in midair, a spaniel's silky ears, the curved tail of an Afghan hound. Each of these soulful photographs captures its subject's singular personality and inner light, and that affable canine charm.
