Chihuahuas are a small dog breed that originated in Mexico, with their roots traced back to ancient civilizations. They are believed to have descended from the Techichi, a small companion dog kept by the ancient Toltec civilization. The modern Chihuahua as we know it today gained popularity in the mid-19th century, particularly during the 1890s when Americans began to explore Mexico and brought back the dogs.
The breed was officially recognized by the American Kennel Club (AKC) in 1904, which contributed to its popularity in the United States and other countries. Chihuahuas are known for their small size, lively personality, and loyalty to their owners. If you're asking about a specific discovery related to Chihuahuas or need more information, please clarify!
