Xoloitzcuintle is the official name of the Mexican Hairless Dog (also known as Perro Pelón Mexicano in Spanish), a canine breed endemic to Central America dating back to Pre-Colombian times. This is one of many native dog breeds in the Americas and it is often confused with the Peruvian Hairless Dog. The name Xoloitzcuintle makes reference to Xolotl because, mythologically, one of this dog's missions was to accompany the dead in their journey into eternity. In spite of this prominent place in the mythology, the meat of the Xoloitzcuintle was very much part of the diet of some of the ancient peoples of the region.
