Chihuahua, the tiniest identified breed, is known for the Mexican state of Chihuahua, where it was 1st noticed in the mid-nineteenth century. The Chihuahua is believed to have been created from the Techichi, a little mute dog kept by the Toltec folks of Mexico so long earlier as the ninth century.


Researchers still theorize on the Chihuahua’s actual origins; however, some think that it leads to the state of Chihuahua-Mexico. Chihuahua is really the biggest of Mexico’s thirty-two states. Their dog-fanciers are thought to have found several of the 1st Chihuahua types in the mid-1800s. In 1884, Mexican sellers started selling the little dog to border visitors, a lot of which took them back to the USA to keep as pet dogs. Earlier, the dog was without an official name. Folks called it after the place where it had been seen. This led to today’s Chihuahua, known as the Arizona (AZ) dog, Mexico dog, Chihuahua dog, and the Texas dog.
