History:

This is the smallest of the pure-bred dogs.  A very old breed with a controversial history.  Some believe the dog originated in China and was brought to the new world by Spanish traders.  Another theory contends that the breed originated in South America. The dog was used by the Aztecs.  When Cortez conquered the Aztecs in the 1500s, the little dogs were left to fend for themselves.  In 1850, three tiny dogs were found in Chihuahua, Mexico.  A few were brought to the US. 

Temperament:

Reserved with strangers, the Chihuahua has an intense loyalty and devotion to a single person. Some may be bold, some timid. They tend to be long-lived 14-18 years.

Maintenance:

The Chihuahua can pretty much exercise themselves running from room to room.  They do not like the cold, but love to lay out on  sunny days and bask in the sun's rays.
