World's tallest dog: Great Dane stands 7'4"

The world's tallest dog stands 7 feet 4 inches tall and resides in Otsego, Mich., according to the Guinness World Records 2013 book published Thursday.

The Great Dane named Zeus is only 3 years old and measures 44 inches from foot to shoulder. He's 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. His owner, Denise Doorlag, says she had to get a van to be able to transport Zeus.
