1. Their origin goes back to the Toltec civilization
According to the FCI standard  , the chihuahua was a wild dog that was captured and domesticated during the time of the Toltec civilization. They are one of the pre-Columbian cultures present living during the Xth and XIIth centuries in North America.
Some theories point out that the ancestors of the chihuahua as we know it today inhabited in Tula (Tollan-Xicocotitlan) in the state of Hidalgo, Mexico. This is due to the well-known figure of "Techichi", which is considered the precursory breed of the current chihuahua.
2. They are one of the bravest dogs
The Chihuahua stands out for being an alert  and very brave dog as indicated by the FCI and AKC standards, respectively. They are also considered an intelligent, vivacious, devout, restless, sociable and faithful dog.
Although each dog is different, the fact is that usually this breed creates a very strong bond with their owners, becoming very attached. It is also common to try to get attention or be jealous.
3. They tremble
Have you ever seen a chihuahua all wrapped up? You probably have, especially during winter. It is not a fashion statement, this is because this breed is especially sensitive to low temperatures, as the AKC highlights.
Does your Chihuahua Trembles a lot? You must know that they do not always tremble because of the cold. Sometimes the source of the trembling is due to excitement, to the fact that they are still in their puppy stage, to fear or to possible hypoglycemia. There are many causes!
4. Chihuahua is not their original name
Indeed, the real name of this breed is "chihuahueño"or Chihuahian", that literally means "arid and sandy place" in tarahumara (Utoazteca language). Chihuahuas are named after the place where they were found, Chihuahua, Mexico.
5. They are born with a soft spot on their cranium
Like human babies, chihuahua puppies are born with a soft spot on their skull. That's because their front panels (the bones of the skull) have not connected totally yet. They should end up doing so during their adult stage.
It is usually a congenital defect  common in toy-sized and teacup dog breeds, such as the shih tzu, the Yorkshire terrier or the Maltese, but can also be caused by hydrocephalus, an infection in the brain, a brain tumor or a a disease that blocks the drainage of the cerebrospinal fluid.
In an article  by the Universities Federation for Animal Welfare on genetic problems of Chihuahua, it is stated that primary hydrocephalus (presence of water in the brain) is one of the most common congenital diseases.
Hydrocephalus causes pressure and pain in the dog's brain, as well as thinning in the bones of the skull. This disease is associated with the size of certain breeds.
6. It is the smallest dog in the world
The Chihuahua is the smallest dog in the world, both in height and in length. According to Guinness World Records, the smallest living dog (in length)  is Brandy, a female chihuahua that measures 15.2 centimeters (5.98 in) from the tip of her snout to the tail. She lives in Florida, United States.
It also records that the smallest living dog (in height)  . It is another female chihuahua named Miracle Milly, which measures 9.65 centimeters (3.79 in). She lives in Dorado, Puerto Rico.
7. They prefer the company of their own breed
If properly socialized, the chihuahua is a dog that relates wonderfully with virtually all breeds of dogs, even with cats. However it is often common to observe how Chihuahua dogs prefer others of their own breed to socialize with. Perhaps this is why it is among the curious facts stated by the AKC.
8. It is one of the most popular dogs in the world
The Chihuahua is one of the most popular and beloved dog breeds in the world. It began to be known in the United States after the broadcast of the Taco Bell ads, in which Gidget the dog appeared (which replaced Dinky). Paris Hilton, Hillary Duff, Britney Spears or Madonna are some of the many celebrities who have decided to adopt a dog of this breed.
9. It is a breed with the widest range of colors
According to the FCI standard  the Chihuahua has two varieties: short-haired or long-haired. In both specimens we can find all kinds of colors or combinations, except the blackbird or hairless dogs.
The long hair specimens have a silky, fine and slightly wavy fur, and also have an inner layer. The most notable feature is the presence of long hair in their ears, neck, extremities, feet and tail. Those who have short hair show short and stuck fur, which sometimes has an inner layer.
10. They have a great lifespan
The Chihuahua is one of the dogs with the longest life expectancy. Relatively few years ago it was estimated that they lived between 12 and 18 years, but currently we can find Chihuahua dogs that are over 20 years old.
If you offer them a good diet, veterinary visits every 6-12 months, good care and much affection, your chihuahua can reach this wonderful number.
