Chihuahua: Dog Breed Info


Chihuahua is an ancient dog breed. Techichi, an older, bigger ancestor of Chihuahuas is first mentioned in Mexico at the time when that region was under Toltecs’ rule. 

However, Aztecs conquered Toltecs and transformed Tchichi into the dog we know as Chihuahua. 

After the Spanish conquistadors cause havoc and conquered the Aztecs, Chihuahua seemed extinct. However, this sturdy dog survived hiding in the remote villages, until Americans came in the 19th century and discovered a breed in the region called Chihuahua. 

The breed was interesting to Americans and soon Chihuahua was famous across the world.

Beppie was the first Chihuahua registered with the AKC in 1908.

Physical Characteristics

Chihuahuas are small dogs from the toy group.


Chihuahuas stand at 5 to 8 inches tall and weigh around 6 pounds.


Chihuahua can have two types of coats: long and smooth.

The long-coated chihuahuas have a slightly curly, long coat with a bit of hair on the ears and feathering on their feet and tail.

On the other hand, smooth-coated Chihuahuas have smooth, short, and shiny hair, with furry tails and hair on the head and neck.

Personality & Temperament

Typical Chihuahua is bold, alert, and wary with strangers. These traits make Chihuahuas great watchdogs. On the other hand, Chihuahuas are sensitive and they enjoy companions and affection.

You will often see Chihuahua bonding with one person.

As it’s the case with all dog breeds, Chihuahuas also need early socialization and exposure to other dogs, people, sounds, and other animals.

Health & Lifespan

Chihuahuas are generally one of the healthiest dog breeds. However, even these small, sturdy dogs are prone to certain health issues. 

The most common ones are:



You don’t worry too much whether your Chihuahua gets enough exercise. Simply, walking by your side and following you around the house is enough exercise for Chihuahua.


Since there are two types of coats, there are also two types of grooming. Generally, smooth-coat Chihuahua is easier to groom as you need to brush her occasionally and bathe her regularly. On the other hand, you need to brush long-coat Chihuahua at least twice a week. Also, trim the dog’s nails and regularly brush your dog’s teeth. 


High-quality food and proper portioning of the meals are all you need to look out for to keep your dog happy, healthy, and in shape.


Chihuahuas are very intelligent and eager to please their owners. Therefore, they are very easy to train and will learn new things fairly quickly. However, they can also be on the stubborn side which can slow down the training process.
