Giant George was a blue Great Dane previously recognised as the world's tallest living dog, and the tallest dog ever by Guinness World Records. There were originally conflicting media reports regarding his height, but the official measurement showed that he was three-quarters of an inch taller than the previous record holder, Titan (at 42. 25 inches (107. 3 cm) at the withers) and an inch shorter than the subsequent record holder, Zeus. His records were announced as he appeared on The Oprah Winfrey Show in February 2010.
