3 Years Ago, Giant George was the World's Biggest Dog and was officially verified by Guinness World Records on February 15, 2010 as the World's Tallest Dog.
Zeus from Michigan is NOW THE WORLD'D LARGEST DOG
He stands 44 inches tall and stretches as limousine-esque 7 feet, 4 inches. Not only is Zeus the tallest living dog now, but he’s the tallest living dog ever. Just be glad he’s a shorthaired animal.
