From dolphins missing their tails to horses unable to trot, custom-fitted animal prosthetics are becoming more and more common. Take a look at some of the prosthetics giving animals of every shape and size a second chance at leading an active life.
Fuji, a female bottlenose dolphin, lost 75 percent of her tail to an unknown disease in 2002.

Oscar lost his back legs after being accidentally run over by a combine harvester in Oct. 2009. But on June 25, 2010 he showed off his new "bionic" legs to the public. The operation took three hours and required the prosthetics to be implanted into the remaining bone.
