(CBS News) When Gonzo started tripping over his food dish three years ago, no one could explain or stop the Alaskan husky's quickly advancing blindness. But a veterinarian offered some simple advice: "Run this dog."
Gonzo, one of 120 dogs at Muddy Paw Sled Dog Kennel, was happy to comply. With help from his brother, Poncho, he soon resumed his place pulling a sled all over New Hampshire's North Country to the delight of tourists and his caretakers, who quickly realized that if Gonzo didn't treat his blindness like an obstacle, neither would they. Given the dog's obvious eagerness, he was allowed to continue on as usual.
