Book excerpt: Featuring sixty black-and-white photographs of old dogs shot by Pulitzer Prize–winning photographer Michael S. Williamson and narrated by Washington Post staffer and columnist Gene Weingarten, this is a perfect collection for dog lovers that celebrates “man’s best friend.” Anyone who has ever loved an old dog will love Old Dogs. In this collection of profiles and photographs, Weingarten and Williamson document the unique appeal of man's best friend in his or her last, and best, years. This book is a tribute to every dog who has made it to that time of life when the hearing and eyesight begin to go, when the step becomes uncertain, but when other, richer traits ripen and coalesce. It is when a dog attains a special sort of dignity and a charm all his own. If you've known a favorite old dog, you'll find him or her on these pages. Your dog might go by a different name and have a different shape, but you'll recognize him or her by the look in an eye or the contours of a life story. There is the dog who thinks he is a house cat; the herder, the fetcher, the punk and the peacock, the escape artist, the demolition artist, the patrician, the lovable lout, the amiable dope, the laughable clown, the schemer, the singer, the daredevil, the diplomat, the politician, the gourmand, and the thief. Plus, as a special bonus, you will find the first Latvian elkhounds ever photographed. Old Dogs is a glorious gift book and a fitting tribute to that one dog you can't ever forget.
