My own interpretation of Xoloitzcuintle.  Is known as the Perro pelón mexicano or Mexican hairless dog. It is characterized by its duality, wrinkles, and dental abnormalities, along with a primitive temper. In ancient times, Xolos were often sacrificed and then buried with their owners to act as guides to the soul on its journey to the underworld. They have been found in burial sites of both the Maya and the Toltec.
