Chihuahua, todays featured dog

The Chihuahua is the smallest breed of dog in the world and is named after the state of Chihuahua in Mexico, where it was discovered in 1850. Some academics believe the Chihuahua to be descended from Chinese hairless dogs—who may have crossed over from Asia to Alaska on a land bridge before continental separation created the Bering Strait—and bred with the ancient Toltec and Aztec Techichi dog, creating the modern-day Chihuahua. The American Kennel Club registered its first Chihuahua in 1905.
