Chihuahuas are named for the Mexican state of Chihuahua, where small dogs of this type were described in the 1800s, and the AKC registered its first one in 1904. Most weigh roughly 3 to 9 pounds, with an apple-shaped head, big upright ears and either a smooth or long coat in nearly any color. Shedding is low to moderate, so regular brushing usually covers it.
Many Chihuahuas are devoted to one or two people and bold for their size. That can show up as barking, wariness of strangers or snapping when handled roughly, so gentle socialization matters. Neighbors in Bartlett's close-set streets will appreciate early quiet training. Dogs vary, and Chihuahuas live 12 to 16 years, so adopting one is a long commitment to a dog that may be a lively young adult or a calm senior.
