In this sequel to her illuminating bestseller The Hidden Life of Dogs, Elizabeth Marshall Thomas profiles the canines in her own household to show how dogs have comfortably adapted to life with their human owners -- and with each other. A classically trained anthropologist, she answers questions we all have about our pets' behavior. Do dogs have different barks that mean different things? What makes a dog difficult to house-train? Why do certain dogs and cats get along so well? How does Snoopy recognize people he sees only once a year, while Misty barks at strangers she sees every day? The Social Lives of Dogs presents marvelous evidence of the power of the group -- and shows us that those who are fortunate enough to be given the trust of an honorable dog will also have their lives enriched.
