Stryker, a Rhodesian Ridgeback, has just turned 105. Translate that into a dog’s life and this wonderfully spirited canine is 15 years old. In his youth he was a Registered Therapy Dog, has been pronounced "Best in Breed" up and down the eastern seaboard and appeared "on camera" for MSNBC, Mercedes Benz, Playskool, Kodak, Purina and Ralph Lauren, to name a few.
