Personality
The Chihuahua tends to bond closely with one or two people, with whom they will be curious, lively and intelligent, as well as deeply and constantly affectionate. However, without adequate socialisation, the breed will not take kindly to strangers and can appear nervous, yappy and even snappy. Chihuahuas must be socialised as early as possible or they will become anxious in new environments and will not get along with strangers, children and other household pets.
The Chihuahua will suit an owner who may have little space in their homes but still want a lively, affectionate companion who will be able to come everywhere with them as this is not a dog who is easily able to tolerate owner absences.

History and Origins
A small dog, called a Techichi, was an important part of Toltec and Aztec cultures. Techichi were the pets of the wealthy and were cremated with the dead in order to take on the deceased's sins so that the person could enter the next world without angering the gods. The dogs were also supposed to guide the deceased through the underworld and fight off evil spirits. Some believe that the Chihuahua is the product of breeding between the Techichi and a small, hairless dog from Asia.
The Chihuahua is a state in Mexico and it’s from this state that the modern Chihuahua dog breed was first exported to America. Theory has it that the modern breed developed from the ancient strains of the Techichi, mixed with small dogs of Mexico, Arizona and Texas.
