American Great Dane, Zeus, confirmed as world's tallest living dog

The Guinness World Record has confirmed Zeus, an American Great Dane from Texas, as the tallest living dog in the world. The two-year-old pup stands at 3 ft. 5.18 inches. 

"He's been a big dog since we got him, even for a puppy," Zeus' owner Brittany Davis told Guinness World Records. "He had huge paws." 

Zeus, who is gray and brown, was born to a merle sire and brindle dam and was the largest puppy in a litter of five.
