The world's tallest dog, and one of Northern California's most famous residents, is suffering from bone cancer.
Earlier this week, veterinarians had to amputate Gibson's right front leg, KCRA reported.
The Guinness Book of World Records lists Gibson, a harlequin Great Dane, as the Tallest Living Dog at 42.2 inches tall, as measured in 2004.
Gibson's owner, Sandy Hall, said the preeminent pooch is expected to return to his Grass Valley home later this week and she expects him to be back in the limelight in just a couple of months.
The site K9 Grass also lists Gibson as a certified therapy dog.
With such an impressive resume, there's no doubt Gibson will be standing tall in no time, despite his health issue.
