The world's tallest dog is a Great Dane named "Giant George" from Tucson, Arizona. Guinness World Records recently made it official -- in fact, they sent someone to measure the big guy. Giant George stands 3 feet 7 inches tall and weighs in at 250 pounds. He measures over 7 feet when he stands on his rear paws. Giant George eats 110 pounds of dog food each week and sleeps in his own queen size bed.
And you thought we had some big dogs in the Carolina mountains!
