GRASS VALLEY, California - Gibson, the California dog dubbed the tallest in the world by the Guinness Book of World Records, has died after a battle with bone cancer.
The 7-year-old harlequin Great Dane from Grass Valley measured 2.16 metres (7 ft 1 inch) when standing on its back legs.
Gibson was diagnosed with the disease in April this year and had his front right leg amputated to prevent its spread. He also underwent chemotherapy as a precaution.
Gibson's owner, Sandy Hall, decided to euthanize Gibson after learning the cancer had spread to his lungs and spine and that no treatment that could save him.
Gibson has appeared on "The Tonight Show," "The Oprah Winfrey Show," and "The Ellen DeGeneres Show
I never knew you, Gibby, but you were the one who founded my love of all big paws. Rest in peace, king of dogs.
