The massive pooch, who measures 7ft 3ins from nose to tail and weighs a staggering 245lb (111kg), could be a prime contender to take the title from former record holder Gibson, who died in August. Now David and wife Christine, of Tucson, Arizona, are awaiting confirmation from Guinness World Records to see if he has achieved the lofty feat.
David said: "He's very, very unique." George eats an unbelievable 110lb of food every month, and sleeps alone in his own queen size bed. David and Christine raised him from a seven-week-old pup, but never expected him to grow so big. The couple eventually had to evict him from their king size bed, when he grew too large for the three of them to share the same sheets.
