Chihuahua dog breed, Chihuahua is thought to descend from the Techichi, a companion dog favored by the Toltec civilization in Mexico. No records of the Techichi are available before the 9th century, although dog pots from Colima, Mexico, buried as part of the western Mexico shaft tomb tradition, which dates back to 300 BC, are thought to depict Techichis. The earlier ancestors probably had been present before the Mayas, as small dogs are found in materials from the Great Pyramid of Cholula, antedating 1530 and in the ruins of Chichen Itza on the Yucatán Peninsula.

In 2018, an analysis of DNA from the entire genome indicated that domesticated dogs entered North America from Siberia for 4,500 years and were later isolated for the next 9,000 years. After contact with Europeans, these lineages were replaced by Eurasian dogs and their local descendants. The pre-contact dogs exhibited a unique genetic signature that is now almost gone. In 2020, the sequencing of ancient dog genomes indicates that in two Mexican breed the Chihuahua retains 4% and the Xoloitzcuintli 3% pre-colonial ancestry.


In a 1520 letter, Hernan Cortés wrote that the Aztecs raised and sold little dogs as food. Colonial records refer to small, nearly hairless dogs at the beginning of the 19th century, one of which claims 16th-century Conquistadores found them plentiful in the region later known as Chihuahua. Small dogs were also used as living heating pads during illness or injury. Some believe this practice is where the idea of pain being transferred to animals from humans originated, which gave way to rituals such as burning the deceased with live dogs, such as the Techichi, to exonerate the deceased human’s sins. Chihuahuas, as we know them today, remained a rarity until the early 20th century; the American Kennel Club (AKC) did not register a Chihuahua until 1904.
