The Xoloitzcuintle (or Xoloitzquintle, Xoloitzcuintli, or Xolo) is one of several breeds of hairless dog. It is found in standard, intermediate, and miniature sizes. The Xolo also comes in a coated variety, totally covered in fur. Coated and hairless can be born in the same litter as a result of the same combination of genes. The hairless variant is known as the Perro pelón mexicano or Mexican hairless dog. It is characterized by its duality, wrinkles, and dental abnormalities, along with a primitive temper. In Nahuatl, from which its name originates, it is xōlōitzcuintli [ʃoːloːit͡sˈkʷint͡ɬi] (singular) and xōlōitzcuintin [ʃoːloːit͡sˈkʷintin] (plural). The name comes from the god Xolotl that, according to ancient narratives, is its creator and itzcuīntli [it͡sˈkʷiːnt͡ɬi], meaning 'dog' in the Nahuatl language.
