There is a belief in some countries that the dog gave the name to the state of Chihuahua since the word "Chihuahua" means "dry and sandy place" in rarámuri, language of the Tarahumara people. Although it is known as Chihuahua, the official name of the race is Chihuahueño, Chihuahua is the name adopted in United States for the race.

Some experts say dogs were among the first native dogs of the Americas, others were brought to the New World after the Spanish conquest of Mexico. Others believe that small dogs may have originated as miniaturized versions of pariah dogs, undefined brown dogs with pointed ears that result when allowed to raise dogs on their own without color selection or other specific characteristics. In any case, race takes its name from the state of Chihuahua, where American tourists at the end of the nineteenth century first found tiny canines.

Chihuahuas were brought to United States by American visitors who visited the North of Mexico and, later, presented at trade fairs Canófilas where they became known to worldwide.

To ensure healthy offspring, a Xoloitzcuintle heterozygous and naked would have to mate with a furry representative. The offspring would be viable, but only half would have no hair. Since the hairy variant is not recognized as a breed in many countries, the mating of two hairless animals is often practiced and the death of non-viable animals is accepted. This circumstance makes the breed controversial and appears again and again in the context of torture breeding..
