Xolotl was the dog god of the Mexica people, commonly known as the Aztecs. He is represented in codices, statuary, and other extant examples of Aztec art as a dog or a god with the head of a dog. While this figure might seem obscure, his name and role echo into the present day through a critically endangered amphibian, a scruffy but loyal companion on an adventure to the afterlife, and, perhaps unsurprisingly, a breed of hairless dog.
