The Chihuahua dog breed‘s charms include his small size, outsize personality, and variety in coat types and colors.
There are TOP 10 interesting facts about Chihuahua.
An early ancestor of the Chihuahua was the Techichi, whose origins are known to go back as far as ninth-century Mexico. Because the breed is so old, the details of the Techichi's origins are lost, but some believe that when European explorers eventually came and bred their own dogs with Techichis, they began the process of creating the modern Chihuahua.
Relative to their bodies, Chihuahuas have the biggest brain in the dog world. They're quick-witted and easy to train. They're not, however, easy to housebreak as a result of a tiny bladder and a willful personality. As desert dogs, they’re also not too keen on the rain or cold.
Remains of ancient Aztec Techichi dogs were discovered in Casas Grandes in the Mexican state of Chihuahua in the mid-19th century. As the modern version of these dogs grew in popularity with American tourists who brought them home to the United States, the breed eventually was given the name "Chihuahua," after the region where it originated.
4) Fierce Breed
Chis are tiny, so they compensate with fierceness. One study found that the tiny pups are one of the most aggressive breeds toward humans and dogs outside their own breed. To combat this, owners are urged to socialize them with other people and dogs early.
5) Soft Head
Like human babies, chihuahuas have a soft spot on their heads called molera. But unlike babies, a chihuahua might have the spot for its whole life. Whether or not a chi keeps its soft spot depends on size, genetics, and skeletal structure. Show dogs aren’t penalized for having them.
6) Smallest Dog
Although the smallest dog in recorded history was a Yorkshire Terrier, the smallest dog breed overall is the Chihuahua. The world's current smallest living dog is a Chihuahua named Miracle Millie, who claimed the Guinness World Record when, on February 21, 2013, she was measured to be an itty-bitty 3.8 inches tall.
7) Wild Chihuahuas
While most Chihuahuas today prefer lounging in their owner's lap, these small dogs were once adept tree-climbers. They've been said to climb trees and near-vertical hills with the grace of a squirrel, presumably for warmth and protection from predators.
8) Marilyn Monroe
Marilyn Monroe owned lots of pets, including a cat, a bird, a horse and several dogs, one of which was a Chihuahua she obtained in 1948 to celebrate signing her breakthrough six-movie contract with Columbia Pictures. Monroe named the Chihuahua Josepha, but the dog was more popularly known to Monroe, her fans and the press by a nickname: "Choo Choo."
The American Kennel Club lists more than 40 different colors and markings in which Chihuahuas can be found, including black, black-and-tan, white, cream, chocolate and red — to name just a few. The breed also is officially divided into the two basic groupings of smooth-coat (i.e., short hair) and long-coat. Some believe the long-coat variety comes from interbreeding with Yorkies.
Living 15 to 20 years on average, the Chihuahua has one of the longest lifespans of any dog breed. Of course, smaller breeds tend to live longer than larger ones, but another key factor contributing to the Chihuahua's longevity is the relatively few health problems to which the breed is predisposed.
