The god in the shape of dog, called Xólotl, was the dedication of Quetzalcóatl to the symbol of Venus, as evening star. This colossal head of stone has been identified by several researchers as the image of this canine deity based on the human ears decorated with the earflaps in the shape of hook, characteristic of the complex of gods related to Quetzalcóatl, and for the dog ears with the tip cut, as they appear in several pictographies representing the image of this god. Xólotl was the god of the double and monstrous beings who accompanied the Sun in it daily trip through the Underworld and participant in several myths of creation. This sculpture appeared in excellent conditions in Tacuba Street, during the excavations for the construction of the Line 2 of the Metro system. The head is painted in red except the earflaps that still preserve the white pigment with which they were covered to represent more faithfully these ornaments, called epcololli in Náhuatl, made of white shell as the majority of Quetzalcóatl's jeweler.Arqlga.
