Dog Breed Review




Small size and a great personality are what define the traits a Chihuahua. Most widely used for dog competitions, this is a breed which is one of the most popular among the people. They are the smallest dog breed and is named after the Chihuahua state. Also called as Chi, they are recognized by the American, UK and New Zealand Kennel Club as toy dogs whereas the United Kennel Club has categorized it under companion breeds.


Though the exact origin of this breed is still unknown, but two significant theories support its history. The myths and the physical findings depict that this breed has its root in Mexico which is why they are named after a state of the same country.

One theory claims that they were brought to Mexico from China by traders, and the traders started to breed them with the different small breed of dogs which is why they have this little size. Another theory is that they are relatives of the Techichi from the Toltec civilization. The Toltec carvings show a small dog with similar traits of a Chihuahua. They were used as a companion dog to the people and were found in Central and South America.

Most of the Techichis were found in the temples as the people of Toltec civilization believed that they had supernatural powers that could take the soul of the dead to the underworld. With that thing in mind, they made a culture to kill a red Techichi and cremate them with the remains of the dead people. This ritual became the part of the western Mexico shaft tomb tradition which was started as late as 300 BC. Though Techichi may seem similar to a Chihuahua, it is still unclear that what the right theory is.

However, the present Chihuahuas were found in the 1850s in Mexico where the Americans liked this breed and took it with them. However, the people were still unaware of the breed. It was 1904 when the first Chihuahua was registered in the American Kennel Club.


The size of a Chihuahua is one of the most distinctive traits of this breed. A Chi’s height would vary between fifteen to twenty-five inches. The average weight will be near to 2.7 kilograms. Both male and female are known to have same physical traits.
