Chihuahuas take their name from the Mexican state of Chihuahua and are among the world's smallest dogs, usually 3 to 9 pounds as pets. The apple-shaped head and big upright ears are classic, and coats come smooth or long in nearly any color. Shedding is low to moderate either way, though long coats need a little more brushing.
Personality runs bold. Many Chihuahuas bond tightly with one or two people, bark at unfamiliar sounds and act far bigger than they are. In Rapid City, that attitude meets mountain lions, rattlesnakes and large dogs on the Rapid Creek path, so a Chihuahua should stay leashed or in your arms outdoors. Chihuahuas of every age are common in shelters, and adults often arrive with settled habits.
