Canis ISSN: 2398-2942 Mexican Hairless Synonym(s): Xoloitzcuintle Introduction Biological Data Introduction General information Originated in Mexico. Two distinct sizes, the standard and the miniature. Being hairless, this breed is very sensitive to both cold weather (literally needing a knitted coat) and is also susceptible to sunburn in hotter weather. The fragile skin needs regular attention and protection from the elements. Some are born with a fine, downy fur, but these are not recognized by the breed clubs. They make an excellent pet, also being a good guard dog with efficient use of their voice as an alarm.
