Chihuahua (dog)


A Chihuahua is the smallest type of dog in the world, named after the Mexican state of Chihuahua. The ferocity of this type of dog depends to a large extent on the behavior of the owner, so the dog must be carefully selected when buying it from a previous owner. Chihuahua fur is light to match the heat of Mexico. 

What did the Chihuahua evolve from?  

In 2018, full-genome DNA analysis showed that domesticated dogs entered North America from Siberia for 4,500 years and were isolated for 9,000 years. After contact with Europeans, these pedigrees were replaced by Eurasian dogs and their local offspring.

Pre-contact dogs showed a unique genetic trait that has now almost disappeared. In 2020, ancient dog genome sequencing indicates that Chihuahuas retain 4 percent of Mexican and 3 percent of pre-colonial ancestry from two Mexican breeds.

What was the original purpose of Chihuahuas? 

Chihuahuas are believed to be descended from the Tchichi (a companion dog favored by the Toltec civilization in Mexico) Records of the Chichi are not available before the 9th century although dog pots are from Colima, Mexico, buried as part of Western Mexico tomb tradition, dating back to 300 BC depicting Chichi.

 The ancestors of the former Chihuahuas may have been present before the Maya, as there are small dogs in the Great Pyramid of Xulua, which dates back to 1530 AD, and also in the ruins of Chichen Itza in the Yucatan Peninsula. 

In a 1520 letter, Hernan Cortes wrote that the Aztecs bred and sold small dogs as food. Colonial records refer to small, almost hairless dogs at the beginning of the 19th century, one of which claims that the 16th-century corticosteroids found abundant in the area are later known as Chihuahuas. It was also used as a living pillow to keep warm during illness or injury.

Some believe that this practice originated the idea of transmitting pain to animals from humans, which gave way to rituals such as cremation of the deceased with live dogs such as taichichi, to absolve the sins of the deceased person. As we know them today, the Chihuahua breed remained rare until the early twentieth century, when the Kennel Club of America did not register the Chihuahua name until 1904. 

In 1884, Mexican merchants began selling the Chihuahua to tourists at the border, many of whom brought them back to the United States to keep pets. At the time, the dog did not have an official name. Rather, people named it after the name of the area in which it was seen.

This led to the modern-day Chihuahua being called Arizona, Texas, Mexico, and Chihuahua. Of course, only one of these names has survived the hands of time, with the breed now being universally recognized as the Chihuahua. 

What are Chihuahuas genetically?

The way Chihuahuas behave based on the genetic characteristics of their parents and grandparents, and their small size makes them sensitive and vulnerable to injuries and attacks from larger animals. Like all dogs, they benefit from proper socialization and training.

Chihuahuas tend to learn best when they are rewarded for good behavior such as being treated or petted. With the proper training a Chihuahua needs, this dog can be extremely intelligent.

The way a dog is trained will affect its behaviour. Chihuahuas are weak and can be frightened easily. It is also generally unsuitable for homes with young children. This type tends to be fierce loyalty to a particular person, and in some cases may become very protective of the person, especially around other people or other animals.

 They tend to have a "kindness intolerance" character and often prefer the company of a Chihuahua over other dogs, and these traits make them generally unsuitable for families with children who are not impatient and calm. . They are often found under the covers or the bed. In the depths of darkness and safety, this is what they consider their den.

Chihuahuas also enjoy time in the sunlight. Sometimes Chihuahuas act like a cat and climb to the highest point on the sofa, usually on top of the pillow, and roll into a ball. Chihuahuas have their and tend to be keen personality. Chihuahuas are not usually fearless and although they are a smaller breed, they do not consider their size a barrier.

Chihuahua dog information

What kind of problems do Chihuahuas have? 

Chihuahuas are prone to some diseases that affect small dogs such as hypoglycemia, tracheal collapse, and dental problems. Chihuahuas can live a long time, often reaching 16 years or more of life. However, it is prone to many of the health problems common to small breed dogs such as the Pomeranian. 

dental problems 

Small breed dogs such as Chihuahuas tend to have problems with their teeth and gums. This is understandable because their mouths are very small, which facilitates dental problems. For example, food is usually trapped between their teeth. This causes plaque and tartar buildup. If not treated, this can also lead to gum disease such as gingivitis as well as premature tooth loss. Chihuahua's teeth are taken care of by daily brushing and regular dental checkups. Junk foods rich in starch and sugar are also avoided. 

lack of blood sugar 

Hypoglycemia, a condition of abnormally low blood sugar, is one of the most common health problems in Chihuahuas. This can cause problems with the nervous system, leading to seizures and possibly coma.

Severe hypoglycemia may occur without warning. Sometimes, your dog may show signs of low blood sugar such as lethargy, weakness, and restlessness.

Therapeutic measures are taken as quickly as possible to keep the dog safe. Even a mild case of hypoglycemia can deteriorate quickly and can lead to permanent brain damage.

The best way of course is to prevent this from happening by taking various precautions. Therefore, when a dog is suspected of having diabetes, a specialized veterinarian should be visited to examine it and determine the necessary medication. 

tracheal collapse 

This condition primarily occurs in older small breed dogs, especially Chihuahuas, Pomeranians, and Poodles. Obese dogs are especially prone to this health problem.

The trachea is made up of cartilage rings. Tracheal collapse occurs because the tracheal rings do not have rigidity

naturally. This causes the tracheal wall to collapse whenever the dog inhales. The collapse of the tracheal wall leads to tracheal stenosis. The symptom of this problem is a goose cough and sometimes rough breathing. These symptoms are also caused by stress. Coughing may also occur when the dog eats or drinks.


This is not a health problem but a Chihuahua tends to shiver, especially under stress or when playing. Small breed dogs have a higher metabolic rate, which causes them to lose body heat faster than other larger dogs - shivering is a way to help generate body heat.

Chihuahuas should always be protected against the cold, so keepers must make sure they keep them with sweaters and blankets in winter.
