It is believed that this dog has existed for more than three thousand years. It was developed in Maya and Toltec cultures, which considered it the Xolote God's envoy, who led the souls of the dead to their allotted place in the next world. Later on, it was used by the Aztecs as a restorative, because they believed that touching its hide or eating its meat can cure diseases. When the Aztecs were conquered by the Spanish, the breed almost disappeared. At the beginning of the 15 century, the interest in this breed revived. A characteristic of this breed is its constant temperature, of about 40°C. It seems to be a combination between the Terrier and the Greyhound.
