Overview
The Xoloitzcuintli — the “Xolo” or Mexican Hairless Dog — is one of the oldest and rarest breeds, coming in hairless and coated varieties and three sizes. Revered by ancient Mesoamerican cultures, it was considered a sacred guardian of the living and the dead.
Calm, loyal, and alert, the Xolo bonds intensely with its family and can be reserved with strangers, making a devoted companion and watchdog. Its warm, smooth skin needs protection from sun and cold, and it thrives on closeness.
History
Dating back over three thousand years, the Xoloitzcuintli was sacred to the Aztecs and other Mesoamerican peoples, believed to guide souls to the afterlife. It survived through the centuries and is a national treasure of Mexico.
