George, the world’s largest dog

Gentle giant George, a four-year-old Great Dane, measures 2.3m (7ft 3in) from nose to tail, putting him on a par with a miniature horse.

This blue Great Dane is, quite possibly, the largest dog in the world. He is a prime contender to take the title from the former record holder Gibson, a harlequin Great Dane, named Boomer the Molosser, who died in August.

‘He’s unique,’ said owner David Nasser, from Tuscon, Arizona. He weighs an impressive 245 pounds.

Mr Nasser and wife Christine have raised George from when he was seven weeks old but never expected him to be so big. They even had to move George out of their king-sized bed, when he grew too large to share the same sheets. George’s owners feed him with 110 pounds of dog food every month.

‘In my 45 years of experience working with giant breed dogs, without question George is the tallest dog I have ever seen,’ said US canine expert Dr William Wallace.
