The Character and the characteristics of Chihuahua Informations

How to Identify an Original Chihuahua.

Chihuahuas are one of the most popular dogs in the United States, as well as one of the most varied.  How can you identify an original Chihuahua?  Here, the identifying characteristics of a well-bred Chihuahua, one that most closely resembles the original breed, will be discussed.


As members of the toy group, original Chihuahuas should not weigh more than 6 pounds (2.8Kg). While most breed organizations do not specify a desired height, Chihuahuas should generally stand between 5 and 8 inches (12/20cm) tall at the shoulder.


There are two types of Chihuahua coats:  long hair, and short hair.  While both types are recognized as distinct breeds, the original Chihuahua is believed to have had a short coat.  Breed experts believe that to create a long-haired Chihuahua, the original short-haired Chihuahua was bred with similar-looking breeds (such as the Papillion) to create a dog with long, flowing fur.  While both types of Chihuahuas are acceptable in the show ring, the most original form of this breed will have a dense, short coat which can feel soft or rough to the touch.

Head Shape

There are two head shapes found in Chihuahuas: “deer head” and “apple head.” The differences between these two head shapes are distinct.

A deer head Chihuahua has a flat-topped head, larger ears, and eyes that are more widely set.  In addition, the deer-head Chihuahua’s legs tend to be longer and slenderer.

An apple head Chihuahua has a more rounded head with eyes that are more closely-set.  This type of dog also has shorter ears and legs.  The American Kennel Club only accepts Chihuahuas with the apple head conformation.

There is much debate as to whether the deer head or apple head Chihuahua more closely resembles the original specimens of the Chihuahua breed.   One theory is that the original Chihuahua descended from the Techichi dog, which had the characteristic apple head shape.  Some breed experts theorize that the deer head Chihuahua is actually a mix between the Techichi and the Chinese Crested dog.  Therefore, many Chihuahua enthusiasts believe the apple head variety of Chihuahua most closely resembles the original breed.

Ultimately, when identifying a Chihuahua that most closely resembles the original breed there are three traits to consider.  The dog in question should weigh no more than 6 lbs, should have a short coat, and should also be of the apple head variety.  While there are many Chihuahua variations (some accepted by the American Kennel Club and some not), these three characteristics are most important.
