Xolos are calm and quiet indoors but alert, closely attached to their family and reserved with strangers. The Miniature keeps the breed's watchful nature in a smaller frame. Coated puppies regularly appear in litters bred from hairless parents.
The hairless dog has smooth, close skin, usually in dark solid shades such as black, slate or bronze, and sometimes a short tuft on the head or feet. The coated dog has a short, flat coat. Both have large, upright ears and a lean, elegant outline. The Miniature is the same dog on a smaller scale.
Xoloitzcuintli (Miniature) dogs are a size variety of Mexico's ancient hairless breed, often shortened to Xolo. The name joins Xolotl, an Aztec god, with the Nahuatl word for dog, and the dogs are said to have been believed to guide the souls of the dead. By the mid-twentieth century the breed had become scarce. In the nineteen-fifties a search for native dogs in remote parts of Mexico helped bring about its revival and its formal recognition. The Xolo was kept as a companion and watchdog, and in pre-Columbian times its warm, bare body was reputedly valued as a comforter. Each size comes in a hairless and a coated form.
