This blue 4-year-old Great Dane named George is a real giant. He could be the world’s tallest dog! He is 43 inches tall (from paw to shoulder), 7ft 3ins (from nose to tail) and weighs 245lbs (111kg)! Another quite interesting detail: George consumes 110 pounds of food every month!! His owners are awaiting confirmation from Guinness World Records to see if he’s actually the tallest dog in the world.. Pictures are really impressive!
