The Chihuahueno It originates in Mexico and receives its name from the Mexican State of Chihuahua, place where it was discovered and domesticated from the wild, In contrast to the belief that exists in some countries that the dog gave the name to the State already that the word “Chihuahua” means “arid and sandy” in rarámuri, language of the Tarahumara people. Although it is known as Chihuahua, the official name of the breed is Chihuahua, Chihuahua is the name adopted in United States for the race.
It is believed that they are descended from a race of ancient Hispaniola island, similar but slightly larger, associated with royalty in the Toltec civilization known as the Techichi (found remains of smaller dogs in ancient tombs at Mexico.
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.

Another theory says that they inhabited the continent because they were brought by the first settlers who passed through the Bering Strait (unproven theory), or that they were brought to Mexico by the Spaniards at the time of the colony from China. Another theory says that the Chihuahua is the result of the intersection of other ancient races that inhabited the ancient Mexico.
One of the first theories was simply living in the wild in the Mexican State of Chihuahua and that they were domesticated by the people of the region until you reach virtually all pre-Columbian Mexico by trade. These dogs came to embark in countries such as: United States, Costa Rica, Cuba, most Hispanic countries and Spain.
But among so much theory, something we can be sure, Chihuahuas are well known for its small size and its long, straight ears.
