A new leg, a new life

Here is another story about some amazing scientists finding new ways to help animals! Check out the National Geographic a photo gallery of animals that are using specially crafted prosthetics to survive. In addition to the dog pictured here with a prosthetic leg, they have fitted an injured bald eagle with a prosthetic beak to help him eat again, new flippers on a sea turtle injured by a shark, a new leg for a elephant injured by poachers, and several other amazing prosthetics that can help injured animals live a better life--and even return to the wild.

I have seen lots of dogs that get around fine on three legs, but what is a human to do with just one? The scientist here have managed to fuse this prosthetic with the dog's bone--something they say could help humans in the future.
