The Xoloitzcuintle is a hairless breed of dog, found in toy, miniature and standard sizes. It is also known as Mexican hairless dog in English speaking countries. […] Hairlessness may have offered a survival advantage in tropical regions. Indigenous peoples of Central and South America had Xolo dogs as home and hunting companions, and today they are still very popular companion dogs. They are also the national dog of Mexico. […] The breed occurs naturally in two varieties, hairless and coated.
