The Chihuahua Is the Smallest Dog Breed in the World

The Chihuahua is officially the smallest dog breed in the world, but what they lack in size they make up for in personality. These tiny dogs typically weigh between 2 and 6 pounds and stand only 5 to 8 inches tall at the shoulder, yet they possess the confidence of dogs ten times their size. The breed originated in Mexico and is named after the Mexican state of Chihuahua. They are among the oldest breeds of the Americas, with a lineage going back to ancient pre-Columbian kingdoms. Chihuahuas come in two coat varieties, smooth and long, and virtually any color combination. Their small size makes them ideal apartment dogs, though they still need regular exercise and mental stimulation. Despite their diminutive stature, Chihuahuas are known for their big personalities and fierce loyalty to their owners.
