LOVELAND, Colo. (WKRC) -- We've seen some great stories about dogs who keep their happy outlooks on life despite missing limbs. Well one dog in Colorado is now able to go for a walk around the block, which is normally not a challenge, unless the dog is a quadruple amputee, like Brutus. Brutus ended up in that state after suffering frostbite on all four paws. His breeder amputated the damage himself, and maimed him. But the 2-year-old is now adjusting to wearing prosthetics on each leg. His foster mom puts Brutus through exercises to help him learn balance with the artificial limbs. Brutus' next step involves physical therapy. He'll also get an improved set of prosthetics.
