Mexican Hairless Dog

The Xoloitzcuintle, or Xolo for short, is a hairless breed of dog, found in toy, miniature and standard sizes.The Xolo also comes in a coated variety and all three sizes can be born to a single litter. It is also known as Mexican hairless dog in English speaking countries, and is one of several breeds of hairless dog.

A genetic study was recently conducted in order to determine the origin of the Xoloitzcuintli breed. The study did not find a close genetic relationship between Xoloitzcuintli and the Chinese Crested Dog. However, the study showed that this breed did not result from a separate domestication of dogs in the New World. Xoloitzcuintli appear to have been a result of a mixture of several Old World dog breeds.
