Few dogs carry as much history as the Xoloitzcuintli, the hairless dog of ancient Mexico. Clay figures of these dogs turn up in West Mexican burial sites, and Aztec belief linked them to Xolotl, a god who guided souls to the underworld. Today the Xolo is Mexico's national dog and comes in toy, miniature and standard sizes, each in hairless and coated varieties. Hairless dogs have smooth, tough skin in shades from black and slate to red and bronze.
Many Xolos are calm, attentive and deeply loyal to their families while staying reserved with strangers, which makes them alert watchdogs without much fuss. They are moderate in energy and usually quiet indoors. Hairless dogs need skin care rather than brushing: regular baths, moisturizer, sunscreen outdoors and a sweater in cold weather. Some adopters with allergies find the hairless variety easier to live with.
