The Xoloitzcuintli goes by just the Xolo or the Mexican hairless dog, even though it also comes in a less common variety with a coat. The hairless version of the Xolo is noted for the absence of all (or nearly all) hair. Sometimes the dog will have a stubbly face and what looks like a mohawk, but is sleekly bare everywhere else on his body.
The Xolo is one of the world's oldest and rarest breeds, according to the AKC, and is the first dog of the Americas. The breed comes in toy, miniature and standard sizes and comes in 10 different colors. With a temperament that can be calm, aloof and trainable, the Xolo is considered a national treasure in Mexico, says the AKC.
