Rin Tin Tin, a pup found in a World War I battle zone, became the world’s first canine movie star, forever marking the German Shepherd Dog as one of the most easily recognized breeds. From his imposing size to his erect ears and dark, intelligent eyes, he has achieved legendary status as the ideal canine. A versatile, athletic and fearless working dog, the Shepherd has done just about every job a dog can do, from leading the blind and detecting illicit drugs to bringing down fleeing criminals and serving in the armed forces. An energetic, loyal and devoted companion, the German Shepherd isn’t a breed but a lifestyle (vetstreet.com).
