The Nez Perce were among the best horse breeders, so it would follow that they produced excellent horse doctors.

“This scene at Rendezvous shows a group of Nez Perce and a white trader observing the initial meeting between a horse doctor and his patient. At some point in the healing process, the horse doctor will open his medicine bag and bring out the magical items and herbs that will, with luck, cure the animal.
