Hairless dog breeds such as the Xoloitzcuintle, Peruvian Hairless, Peruvian Inca Orchid, and Khala are generically considered pila which simply means "without hair”. They are the oldest known dog breeds to live with people. Most of them were used to hunt small game, thus they have a high prey drive. They were raised as guard dogs, for medicinal purposes, and yes, even as food. Now, we consider them friends, companions, and family members.
