After first being discovered in the 1850s in Mexico, the Chihuahua was first registered with the American Kennel Club in 1904. The breed is named after the Mexican state Chihuahua in which they were found, a region that borders Texas and New Mexico. However, this isn't where the breed originally came from. Rather the breed comes from the ancient Techichi breed of dog that belonged to the Toltec Civilization near Mexico City.

The breed wasn't discovered outside of Mexico until the 1850s and soon after it became very popular throughout the world. In 1904 it was first registered with the American Kennel Club in the modern breed we see today. Today there remains the smooth-coated, vocal Chihuahua and the more traditional longhaired Chihuahua breed.

Officially the American Kennel Club describes the Chihuahua breed as graceful, alert and agile with a compact and terrier like quality. Although every dog of this breed has its own unique personality some Chihuahuas can be terrier like to the extreme and be very grumpy, haughty or even nasty if they are provoke. However, more often then not the Chihuahua is a dog with curiosity, intelligence and loyalty that makes them a wonderful companion.

This terrier like quality doesn't make the Chihuahua a good breed for large households or those with small or noisy children because of their clannish tendencies and suspiciousness of other people. But the curiosity, intelligence and extreme loyalty of the breed make them an excellent pet for the elderly, individuals and disabled people.

But for the individual or elderly couple they can be an excellent pet that loves to be pampered and are good for apartment living or those with limited incomes. It is best to get a feel for the temperament of a Chihuahua before determining if this is the right breed for you.

Despite the Chihuahuas small size, they often aren't aware of it. Many times a Chihuahua will be much bolder than other dogs that are three times or more their size. Because of their fierce loyalty to only one or two individuals the breed will often become highly protective of their owners. It is because of this nature that they are often wary of strangers or any new guests that are introduced to the household that the Chihuahua considers it's personal domain.

A Chihuahua requires a lot of human contact in the form of touching, petting and general attention. Without this, the breed often resorts to various attention getting tricks until they gain attention.

This makes the breed seem too needy for some, but you can get so much back if you just give the Chihuahua love, affection and care.
