The Maya had two varieties of Canis familiaris, the xoloitzcuintli, otherwise known as a Mexican Hair-less, and the tlalchichi (techichi in Mayan), a smaller, hirsute variety introduced into Maya culture by the Toltecs. Together, they were both known as pek, or dog. The xolo is medium sized animal (35-45 pounds) with smooth slate or reddish-gray skin that often has white spots or blotches. Not all of the dogs are born hairless; they are heterozygous, with one recessive gene for a normal coat, and one dominate gene for hairlessness. A mating of two xolos generally results in a litter consisting of 25% of the puppies with hair, 50% hairless puppies, and 25% stillborn (the fate of the ones with two recessive genes). These larger xolos were used as hunting and guard dogs by the Maya. The smaller Techici had another use.
An alux (Mayan: [aˈluʃ], plural: aluxo’ob [aluʃoˀːb]) is the name given to a type of sprite or spirit in the mythological tradition of certain Maya peoples from the Yucatán Peninsula and Guatemala. Aluxes are conceived of as being small, only about knee-high, and in appearance resembling miniature traditionally dressed Maya people. Tradition holds that aluxes are generally invisible but are able to assume physical form for purposes of communicating with and frightening humans as well as to congregate together. They are generally associated with natural features such as forests, caves, stones, and fields but can also be enticed to move somewhere through offerings. Their description and mythological role are somewhat reminiscent of other sprite-like mythical entities in a number of other cultural traditions (such as the Celtic leprechaun, the Scandinavian Gnome, or the European Troll and Gremlin), as the tricks they play are similar.
