Likenesses of Chihuahua-like dogs decorate the artifacts of lost civilizations around the world. Trading among ancient cultures was more widespread than commonly assumed, so it is no surprise that similar dog types took root in far-flung places. How the Chihuahua type first came to the peoples of Mexico, however, is a secret of prehistory. We do know that when the Toltecs held sway in Mexico about a thousand years ago, their breed of choice was the Techichi, a larger, heavier ancestor of today’s Chi.
Modern Chihuahuas hail from Chihuahua, Mexico. They are the smallest dog breed and the oldest North American breed. They rocketed to popularity in the U.S when famous Latin musician Xavier Cugat made a Chihuahua his constant public companion, and remain extremely popular to this day. Famous Chihuahuas include the Taco Bell Chihuahua, Ren from 'Ren and Stimpy', and Ducky, the 2007 ‘Guinness Book of World Records’ winner for ‘World's Smallest Living Dog'.
