The Chihuahua is the tiniest dog breed, and its history is somewhat of a controversy. Some believe that the breed originated in China and was imported to the new world via Spanish traders, where it was crossed with small native dogs. Others think it originated in Central and South America and is a descendant of the native Techichi, a small mute dog sacrificed in Toltec religious ceremonies. According to their religion, a small red dog led the soul to the underworld, and mostly every Aztec family had such a dog that was offered and buried with any deceased member of the family.

Unfortunately for the Techichi, the Toltecs and their conquerors, the Aztecs, consumed dog meat and were sometimes on the menu. However, the Techichis were well taken care of during life by the priests or their families and lived very short lives. The most probable origin of the Chihuahua is a mix of the following beliefs: the native Techichi was most likely crossed with tiny hairless Chinese dogs. However, the date when this was supposed to have occurred is controversial.

The Chinese dogs most likely came over when a land bridge spanned the Bering Strait, or Spanish traders imported them later. When Cortes conquered the Aztecs in the 16th century, the little dogs were abandoned and left to survive on their own. Some 300 years later, three small dogs were located in Chihuahua, Mexico, in 1850. A few were imported to America, but they stirred up very little attention.

Only when the rhumba king, Xavier Cugat, was seen in public with one as a constant companion did the breed finally capture the public’s hearts. The dogs experienced a rapid rise in popularity and continue to be one of America’s top dogs.

Chihuahua Temperament

According to the AKC standard, this breed is considered “terrier-like” and, ideally, fearless and self-assured. These dogs are brilliant with solid instincts, and many possess a pronounced prey drive. Chihuahuas are also devoted, protective, and courageous, making them excellent watchdogs; this can get them into trouble, though, as they will not think twice to take on a possum, raccoon, bigger dog, or burglar.

Potential owners need to be prepared to step in to prevent altercations with dangerous adversaries. The small size of the dog intensifies the need for training and socialization. Because of its size, a Chihuahua can become defensive, shy, or excessively clingy if not consistent and positively socialized.

Thanks to its intense devotion to a single family member, the Chihuahua has earned its rightful place as a favored and loved dog. The dogs are reserved with strangers but excellent with other pets and dogs within the household. Most try to offer protection but are not particularly effective.
