In this August 26, 2011 photo provided by OrthoPets, shows Naki?o, a red heeler mix breed, the first dog to receive four prosthetic limbs at Denver, Colo. Naki?o was found in the cellar of a Nebraska foreclosed home with all four legs and its tail frozen in puddles of water-turned-ice. What frostbite didn?t do, a surgeon did, amputating all four legs and giving him four prosthetics. (AP Photo/OrthoPets, Lindsey Mladivinich)
