Meet the world's tallest living dog, and boy is he a big un'! Measuring a whopping 2.2 metres on his hind legs, Zeus the Great Dane has been officially awarded the title of world's tallest dog by the Guinness Book of Records. He stands 1.12 metres from paw to withers. Owner Denise explains: "The most common thing people ask is: 'Is that a dog or a horse?" Weighing in at 70.3kg (over 11 stones), the giant canine eats his way through a 14kg bag of dog food each DAY! "We had to get a van to be able to transport him, oh, and if he steps on your foot he leaves bruises!" says Denise.
