Crueahtong Kayan is a vet who works at a veterinary hospital in northern Thailand specializing in the treatment of elephants. She is treating 12-year-old female elephant, Mosha, which lost her front right leg at the age of 7 months after she stepped on a mine. Mosha now uses a prosthetic leg, which needs to be resized regularly as she grows larger. Crueahtong hopes one day Mosha will be able to walk in the forest like other elephants do.
