It is characterized by its sparse hair coat and a severe oligodontia. This phenotype is a consequence of Canine Ectodermal Dysplasia caused by a mutation on the Foxl3 autosomal gene. It is also known as the Mexican hairless dog in English-speaking countries and is one of several breeds of hairless dog.

A 1999 genetic study using mitochondrial DNA found that the DNA sequences of the Xoloitzcuintle were identical to those of dogs from the Old World, and did not support a New World domestication for this breed. This early study did not find a close genetic relationship between Xoloitzcuintle and the Chinese Crested Dog, another hairless breed that is cited by the American Kennel Club as an ancestor to the Xoloitzcuintle./wikipedia
