Chihuahua Origins: The History of Chihuahuas

Although the origins and history of Chihuahuas are the subjects of discussion, it does seem likely that this breed emerged in Mexico.

Chihuahua is the name of a Mexican state that shares borders with Arizona, Texas, and New Mexico. It is believed that these dogs entered the United States because they were sold to visitors crossing the border.

There is speculation that Chihuahuas trace their ancestry back to the Toltecs, an ancient tribe within ancient Mexico, who bred the Techichi as pet animals. The Techichi was the maiden name of the Chihuahua, a little, deaf dog from the Toltec people of Mexico maintained as far back as the ninth century A.D.

According to Toltec belief, Techichi were sacred animals that guided the soul to the afterlife. This superstition led to the burial of many Techichi with their masters. Chihuahuas may have ancestors older than the Techichis as part of their heritage.

Artifacts depicting little, large-eyed dogs similar to Chihuahuas were discovered in El Salvador, Mexico, and the United States. They date to approximately 100 A.D. and may have been a part of a kid’s toy.
