Anyone who has ever loved a dog, young or old, will warm to this stirring tribute to our best animal friends. Award-winning photographer Nancy LeVine has traveled the length and breadth of America -- from Kauai to Martha's Vineyard, from Seattle to Natchez -- to meet and photograph some of our most endearing senior canine citizens. Included here are 86 of her finest portraits.These gallant companions ride on our tractors, doze on our couches, happy to be in our company. They remind us of the best in ourselves, and as they lose their vigor and youth, they reflect our own inevitable aging with courage and calm. Nancy's photographs perfectly capture the enduring appeal of these elderly dignified beings in the places where they belong -- all across America. As "America's Veterinarian," Dr. Marty Becker, says, "These images can make you laugh, cry, and simply feel the nobility of elder dogs."
