    Chihuahua History

    In this article, we discuss the origin and history of Chihuahuas in detail. According to animal experts, the history and origin of Chihuahuas are very old and interesting. The Chihuahua is named after the Mexican State of “Chihuahua” which shares the borders with Texas and New Mexico in the United States. Recently, it has been confirmed that the Chihuahua’s ancestors were from Chihuahua by DNA analysis. 

    Chihuahua is the faithful companion of man since the ancient days, but they were first noticed in the mid 19th century in the Chihuahua state of Mexico. They are typically alert and playful dogs with a weight of a few pounds and a height of few inches. The Mexican origin of Chihuahuas is confirmed by both archaeological and folklore finds.

    Researches at KTH Royal Institute of Technology in Stockholm analyzed the DNA samples of Chihuahuas to confirm the origin and history. They matched the DNA samples with archaeological specimens. The results were confirmed that the modern-day Chihuahuas share a DNA type with the pre-Colombian era dog samples collected from Mexico. 

    The findings of this research have also supported the connection between the origin and Chihuahuas to the Techichi (a desert dog that dates back to the Mayan times). According to the archaeological experts, the Toltecs civilization were the first people who domesticated the Techichi. They may have been further developed the breed with the crossbreeding the Techichi with a dog breed that populated the mountains of Chihuahua, called the Chihuahueno at that time. 

    When the Aztec people became the ruler of Mexico, they started keeping the Techichi as their companions and used them in religious ceremonies. This hypothesis is supported by the carvings found in Aztec temples and pyramids. 

    When explorers came to Mexico, it is believed that the Techichi was bred with the dog which they brought and the resulting specie was the Chihuahua that we have today. Several facts support this statement. For example, the variation of colors that can be found in the Chihuahua breed today is due to the breeding process we have discussed above.

    Are Chihuahuas smart?

    In this section, we are going to take a closer look at Chihuahua intelligence. Chihuahuas are considerably smart but not as smart as many other dog breeds. The Chihuahua’s ranking of obedience intelligence is below average in comparison with other pet dog breeds. However, they know about their intelligence. 

    As we have mentioned earlier, Chihuahuas have the biggest brain-to-body size ratio among all other dog breeds, but surprisingly, they are not top-ranked intelligence dogs. In 1994, Stanley Coren, who was a psychology professor, wrote the book “The Intelligence of Dogs”. He observed the intelligence of 199 dogs rank them from 1 to 138. The ranking was based on two key questions:

    1. In how many repetitions, a dog can learn a new command? (The intelligent dogs learn command in less repetition and faster)
    2. What is the success rate of a dog obeying on the first attempt a known command? 

    According to Coren’s ranking, Chihuahuas come in 125th position out of 138 breeds. This ranking has put them in the category of “fair intelligence”. Coren determined that Chihuahuas can learn a new command between 40-80 repetitions. The success rate of Chihuahua’s obeying on the first attempt at a known command was around 50%.

    On the other hand, Border Collies is ranked 1st in Coren’s ranking which requires only 5 repetitions to learn a new command with a success rate of 95% in obeying a known command. It means Chihuahuas require about twice the time of the average dog to learn a new command. 

    The overall intelligence of Chihuahuas can be assessed by measuring the following types of intelligence:

    • Instinctive intelligence

    Instinctive intelligence is the intelligence the dog was bred for. For example, a gaming dog has instinctive intelligence for collecting birds during a hunt while a herding dog knows how to round up animals. In the case of Chihuahuas, instinctive intelligence is for ratter and guarding. They are also bred as companion dogs. 

    • Adaptive Intelligence

    Adaptive Intelligence is a type of intelligence that a dog can learn to do something for himself. Different dogs can have different adaptive intelligence, no matter if their breed is the same. Chihuahuas also learn adaptive intelligence according to their environment. 

    • Obedience intelligence

    Obedience intelligence covers all the things and commands which a dog learns from humans. For example in the case of Chihuahuas, humans instruct them different commands such as sit, paw or stay, etc. The Coren’s ranking was on the basis of obedience intelligence. 

    In short words, Chihuahuas are intelligent enough to learn all the necessary commands which makes them a perfect companion dog. So, you shouldn’t worry about the intelligence of your beloved Chihuahua.
