The earliest of these were found at Tres Zapotes in Veracruz, Mexico, which dates to 100 AD, indirect evidence that a Chihuahua-style breed was in Mexico over 1400 years before the first Europeans arrived.Dog effigy pots dating to around 1325 AD discovered in Georgia and Tennessee also appear to represent the Chihuahua. In 1850, a pot featuring the Chihuahua-style dogs was unearthed in old ruins at Casas Grandes in the Mexican state of Chihuahua, which dates from 1100–1300 AD showing the long history of such dogs at this site, although most artifacts relating to its existence are found around Mexico City. These traits generally make them unsuitable for households with children who are not patient and calm.Because Chihuahuas get cold easily they tend to love their dens and will often burrow themselves in pillows, clothes hampers, and blankets. Chihuahuas also enjoy time in sunlight. As in other breeds with large protruding eyes, Chihuahuas are prone to eye infections and eye injury. The eyes may water in response to dry air, dust, or airborne allergens.
