The biggest dog in the world born in 2002, Gibson took the title of the world's tallest dog from 'Harvey', who measured 41 inches, in 2004. Standing at 42.6 inches tall from paw to shoulder, Gibson, the giant Harlequin Great Dane passed away in August near Sacramento, Los Angeles.
A Blue Great Dane called George that stands at nearly 43 inches tall and weighs a staggering 245 pounds, could become the tallest dog after an application to the Guiness Books of Records.
The four year-old dog’s owners, David and Christine Nasser, have written to the Guinness World Records asking if their pet has become the biggest in the world.
The couple, from Tuscon, Arizona, hope he will take the crown from the former record holder, Gibson, a harlequin Great Dane who passed away from cancer last August.
George, who looks more like a miniature horse than a dog, measures almost the same, at 7 ft 3 inches from nose to tail and 42.625 inches at the shoulder.He consumes 110 pounds of food every month and sleeps alone in his own Queen Size Bed.
Mr Nasser said they were awaiting confirmation from Guinness World Records to see if he has achieved the new record.
Dr. William Wallace of the Buena Pet Clinic in Tucson, who witnessed the documentation necessary for the Guinness record, said: “In my 45 years of experience working with giant breed dogs, without question, George is the tallest dog I have ever seen.”
