The history of Chihuahua is a bit complicated as many theories explained the origin of this breed. According to archaeological and folklore, this dog breed is believed to have originated from Mexico. However, the most popular theory is that Chihuahuas descended from a dog called Techichi, a South or Central American dog. 

Chihuahuas are known to be North America’s oldest dog breed. Although there have been no records of Techichi, there are dogs from Colima, Mexico known to depict Techichis. In the mid 19th century, the modern Chihuahua was discovered in Mexico. The Chihuahua was named after a state in Mexico. According to some experts, the Incas or Aztecs this dog breed while others traced it to Spanish dogs. History recorded that the Aztecs took hold of the Techichi when they conquered the Toltecs. 

According to the Aztecs, the Techichis were powerful, they could see the future, guide dead souls to the underworld, and they could heal the sick. The Techichi was also used as a source of food. However, this dog became obscure after the Aztecs were conquered by the Spanish in the late 16th century. Another theory reveals that the Spanish traders brought the small hairless dogs from China to Mexico and they were bred with some native dogs. 

According to the information obtained from the Chihuahua Club of Victoria, it was revealed that the first four Chihuahuas that came into Australia occurred in 1955. It is from these four that the establishment of the famous breeding line (Chicdale) came to be. The Chihuahua club of South Australia revealed that the very first female Chihuahua was owned by Mrs R Truscott in the year 1958.
