After having his paw amputated because of a tumor, Sunny the dog had to wear a prosthetic that kept breaking. That's when his owner stepped in and decided to create a custom-designed prosthetic using one of his old tennis shoes.
Built from an old Nike Zoom Vapor 9 sneaker and some duct tape, the new prosthetic works much better for Sunny. The dog's owner, Don Chernoff, posted a video on YouTube of Sunny walking and playing in the snow with his new paw, moving around just like any other canine.
"Now Sunny is a Nike dog!" Don wrote on YouTube. "Roger Federer would be proud."
