Abandoned as a puppy when his owners fled their foreclosed-upon Nebraska home, Naki’o lost all four of his paws to severe frostbite after stepping into a freezing puddle in the home’s abandoned basement. He was rescued, but forced to crawl on his belly to get around. Happily, new owner and veterinary technician Christie Tomlinson successfully organized a fundraiser to have Naki’o’s two back legs fitted with OrthoPets prosthetics. When Naki’o enthusiastically took to his new hind-legs like they were the real deal, OrthoPets founder Martin Kaufmann decided to complete the set free of charge, making Naki’o is the first dog to ever be fitted with four prosthetic limbs.
