A Great Dane named Zeus has been officially recognized as the world's tallest dog by Guinness World Records. The 3-year-old canine measures 44in from foot to shoulder and 7ft 4in when standing on his hind legs—the same size as an average donkey. "We had to get a van to be able to transport him. Oh, and if he steps on your foot he leaves bruises," said owner Denise Doorlag. More info and video at metro.co.uk.
