Rin Tin Tin, the most famous German Shepherd of all, was originally rescued from a World War I battlefield. In a small French village called Flirey, Corporal Lee Duncan found a damaged German kennel with a starving dog and five puppies inside. The dogs were rescued and one of the puppies was named Rin Tin Tin. He would later become a silent film star, appearing in a total of 28 movies.
