What's a dog for? : the surprising history, science, philosophy, and politics of man's best friend / John Homans.

Includes bibliographical references and index.

With deep intelligence, a little humor, and compelling reasoning, Homans (executive editor, New York magazine) thoughtfully examines the complex world of dogs and how their bonds with people have evolved in modern times. Even in the past 40 years, dogs are treated more like family members than livestock, with careful attention given to their comfort, diet, exercise, and emotional and intellectual stimulation. Quoting Charles Darwin, James Thurber, and John Updike and drawing from books such as Alexandra Horowitz's Inside of a Dog: What Dogs See, Smell, and Know, Homans pulls together a cohesive exploration of what science has learned about the culture (both human and canine) of dogs, from their ancestral beginnings to their diverse physical and cognitive status today. He also draws on international scientific studies to bolster his discussion of the rapid paradigm shift in human attitudes toward dogs and how this influences the politics of puppy mills, kill shelters, dog shows, property rights, dog fighting, and even dog food.
