The Chihuahua (/tʃɪˈwɑːwə, -wɑː, -ˈwaʊ.ə/ (listen); Spanish: chihuahueño) is the smallest breed of dog, and is named after the Mexican state of Chihuahua. The earlier ancestors probably were present before the Mayas as dogs approximating the Chihuahua are found in materials from the Great Pyramid of Cholula, antedating 1530 and in the ruins of Chichen Itza on the Yucatán Peninsula. However, a genetic study indicated that there was less than 2 percent pre-European mitochondrial DNA in modern Chihuahuas due to admixture with the European dogs. Pet Chihuahuas (that is, those bred or purchased as companions rather than show dogs) often range above these weights, even above 10 lb if they have large bone structures or are allowed to become overweight.
