Chihuahua Dog History and Origin
The Chihuahua gets its name from the Mexican state of Chihuahua, where the breed was discovered in the mid-19th century. However, its roots go back even further. It’s believed that Chihuahuas are descendants of the ancient Techichi dogs, kept by the Toltec civilization in Mexico around 1,000 years ago.
These dogs were considered sacred and were believed to have spiritual powers. Over time, they became smaller and more domesticated — eventually evolving into the modern Chihuahua we know today.
