The giant, who measures 7ft 3ins from nose to tail, could be a prime contender to take the title from the former record holder, Gibson, a harlequin Great Dane who passed away from cancer last August.
Now George's owners, David and Christine Nasser, are awaiting confirmation from Guinness World Records to see if he has achieved the lofty heights.
'He's 42.625 inches at the shoulder,' said David. 'He's very very unique.'
According to David, George consumes 110lbs of food every month, and sleeps alone in his own Queen Size Bed.
