🐀 Are Chihuahuas Dogs or Rats? (Debunking the Myth)

The Chihuahua is the smallest of all the dog breeds. It has a height of approximately 15-23 cm (about 9.06 in) on average, though some may grow to 30cm (about 11.81 in) or even 38cm (about 1.25 ft).
The tiniest Chihuahuas, also known as teacup Chihuahuas, are in high demand, therefore many readers try their best to keep their Chihuahuas as small as possible.
Due to their diminutive size, there was widespread speculation that Chihuahuas are not really dogs but rodents. Many people have pointed out the close likeness in appearance between Chihuahuas and a rodent, but are Chihuahuas dogs or rodents on a genetic level?
Are Chihuahuas actually dogs?
In 2004 an article by the Wately Review claimed that researchers after analyzing the DNA of 85 dog breeds concluded that the Chihuahua was, in fact, a type of oversized rodent and not a dog. This led many to speculate - are Chihuahuas dogs or rodents?
However, this article was a false claim written purely as a satirical news article by the website owners’ own admission in the “About” section of the site.
The Watley Review stated in 2004 that the Chihuahua was a large rodent and that it was selectively bred for many centuries to resemble a canine. The article stated that scientists at the Fred Hutchinson Cancer Research Center in Seattle had undertaken a study in which they analyzed 414 DNA samples from 85 breeds of dog.
Peggy Wilson who was the president of the Chihuahua Club of America said that they used 96 distinct patterns called “microsatellites” in dog’s genes that were then used by researchers to compare dogs within the same breed as well as one breed with another. At the end of the study, they concluded that each breed was genetically distinct.
It should be noted here that The Watley Review is not based on journalistic merit, or any facts and that names, events and places are fictitious. However, this confusion led some people to believe that the Chihuahua did originate from rodents.

Are Chihuahuas related to rodents?
As a result of the Watley Review article, people began to wonder whether the Chihuahua was a dog or a rodent. Future studies proved that the Chihuahua has no genetic connection to rodents, much to the relief of Chihuahua enthusiasts everywhere.
Chihuahuas, like other dogs, are descendants of wolves. In 1904 the American Kennel Club stated that Chihuahuas are a “reputable and recognizable breed” and are of exacting standards.

For the sake of clarity let’s take a look at where the Chihuahua originated. Research into the DNA and history of the breed has shown that the Chihuahua's ancestors entered North America during the ice age when more land was still accessible than it is today. The Chihuahua was then bred from a different breed native to Mexico by the native people.
Today the Chihuahua’s original breed is extinct either because they were interbred with other dogs to a point that they no longer existed, or as another theory suggests, they were hunted to extinction and eaten by the Spanish.
Nowadays, there are varying versions of the Chihuahua that vary in color and coat.
