The Chihuahua is the smallest breed in the world and native to the Mexican state of Chihuahua.
The origins of the breed are unclear but it is thought to related to the Fennec Fox, although there are theories that it may be related to a companion dog of the Toltec tribe from Mexico, called Techichi.
Chihuahuas are prone to some mental illnesses such as epilepsy and seizures. Eye problems such as dry corneas and secondary glaucoma are common due to their bulging eyes. Chihuahua's are also prone to become overweight and as with all dogs need regular walks. Did you know that chocolate is a poison to Chihuahua's?
Chihuahua's are mostly born via a caesarean section because the heads of the pups are too large and because of their petite size, young need to be handled very carefully to prevent breaking any bones.
As pets, Chihuahua's are very lively, cheerful and agile and make excellent companions.
