The Xoloitzcuintli (pronounced “show-low-eats-queen-tlee”), also known as the Tepeizeuintli, the Pelon, the Bald Dog, Perro sin Pelo Mexicano, the Mexican Hairless or simply the Xolo (“show-low”), is one of the oldest and rarest of all domestic dog breeds. It was first developed in ancient Aztec civilizations, where it was used as a watchdog, guard dog, companion and food source for tribal peoples. Most Xolos are hairless, with wrinkled skin that some people say resembles the skin of a tiny shrunken elephant. The breed also comes in a coated variety, which is referred to as the “powder-puff.” Both powder-puff and hairless Xolos are recognized in three distinct sizes – Standard, Miniature and Toy – with Toy being the tiniest. In fact, today these are considered to be three separate breeds, although here we will address them as one as their standards are identical except for differences in height and weight. The breed was recognized by the American Kennel Club for full registration status in 2011. It is a member of the Non-Sporting Group. Today’s Xolos make affectionate, low-maintenance indoor companions.
