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 has both hairless and coated types, with the latter fully furred. 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 wrinkles and dental abnormalities. In Nahuatl, from which its name originates, it is xōlōitzcuintli [ʃoːloːit͡sˈkʷint͡ɬi] (singular) and xōlōitzcuintin [ʃoːloːit͡sˈkʷintin] (plural). The name comes from the Aztec god of fire and lightning Xolotl that, according to ancient narratives, is its creator and itzcuīntli [it͡sˈkʷiːnt͡ɬi], meaning 'dog' in the Nahuatl language.
