It is always a tragedy when a man's boyhood heroes pass away. For some among us it was pop-star Michael Jackson, others director John Hughes.

For the Asylum team it was Gibson, the tallest dog in the world.

The Guinness Book of World Records had long recognised Gibson, a Harlequin Great Dane who measured 7 ft 1 in standing on his hind legs and 42.6 inches from ground to shoulder, as the loftiest canine on the globe.

Sadly, though, Gibson died on August 7 as a result of bone cancer. He had been diagnosed with the disease in April, but neither a leg amputation of chemotherapy could save him and he was eventually put down with the consent of his owner Sandy Hall to avoid a more painful end.

Throughout his seven-year life Gibson used his fame for good. He became a "spokesdog" for a canine cancer charity and was nominated for the American Kennel Club Award for Canine Excellence. According to his website Gibson even co-authored a book - though we cannnot confirm its quality, if someone wants to buy us a copy we promise to read it cover to cover.

Fans and supporters of Gibson are directed to his website where they can donate to his chosen charity, and even to help with his funeral expenses. (Seriously.)

The good news for fans of tall dogs is that Gibson's son, Brewster, is already 38 inches tall from ground to shoulder and looks set to reclaim his father's title. If there is any justice in the world we expect the Hollywood movie version of Gibson's life to hit cinemas in 2011.
