1. Aztec Companion Dog: One widely accepted theory suggests Chihuahuas originated in Mexico, possibly from the Techichi, a small hairless dog kept by the Aztec civilization. These dogs were believed to be companions, possibly even used for medicinal purposes.
2. Toy Breeds from Asia: Another theory proposes that Chihuahuas might have been developed from toy breeds brought to Mexico by Spanish conquistadors who, in turn, had obtained them from Asia.
3. Natural Selection: Some believe Chihuahuas evolved naturally from smaller wild dogs in the Mexican region.
The Exact Purpose:
While the exact purpose for which the Chihuahua was developed remains unclear, it is believed that they were primarily companion dogs. Their small size made them easy to handle and transport, and they were likely cherished for their loyalty and affection.
It's important to note: The origin of the Chihuahua breed is still debated among experts, and there's no definitive answer. However, their history in Mexico is undeniable, and they have been popular companion dogs around the world for centuries.
