The Guinness World Records 2013 book published last week recognizes Zeus of Otsego, Mich., as the world's Tallest Dog. The 3-year-old measures 44 inches from foot to shoulder. Standing on his hind legs, Zeus stretches to 7-foot-4 and towers over his owner, Denise Doorlag. Zeus is just an inch taller than the previous record-holder, Giant George. Zeus weighs 155 pounds and eats a 30-pound bag of food every two weeks.
