Techichi
The Techichi was a small companion dog of pre-Columbian Mesoamerica, especially associated in later accounts with the Toltec and Mexica or Aztec cultures of central Mexico. It is known from archaeology, colonial writing, and ceramic figures rather than from a modern breed standard. These dogs were probably compact, short-coated, and variable in color, and they are often discussed as part of the ancestry of the Chihuahua, although that relationship is not a simple one-to-one pedigree.
Because the Techichi is extinct as a documented population, people cannot responsibly buy or breed a pure Techichi today. The name appears in historical research, museum interpretation, and sometimes in marketing for Chihuahua-type dogs, so buyers should treat modern claims cautiously. Stewardship of the subject belongs more to archaeology, genetic study, and accurate breed history than to pet keeping, while living toy dogs still need ordinary companion-dog care rather than assumptions based on ancient depictions.
