The Chihuahua is named for the Mexican state of Chihuahua and is one of the world's smallest dogs, with an apple-shaped head, big upright ears and a smooth or long coat in nearly any color. Adoptable Chihuahuas often weigh 3 to 9 pounds, a bit more than the show standard, and many live 12 to 16 years.
In Lee's Summit's subdivisions, a Chihuahua's confidence tends to show up at the front window and the fence line, where barking at passersby is common. Gentle socialization and short, steady training help a lot. Chihuahuas vary: one may be clingy, another aloof or playful, so a dog's own personality tells you more than the breed label does.
