Chihuahuas take their name from the Mexican state of Chihuahua, and the AKC registered its first one in 1904. The apple-shaped head, large upright ears and smooth or long coat in nearly any color make them easy to recognize. Most adoptable Chihuahuas weigh between 3 and 9 pounds, and lifespans commonly run 12 to 16 years.
Many are bold, alert and devoted to one or two people, with a big-dog attitude that can show up as barking or snapping when handled roughly. In Savannah, where small dogs share sidewalks with joggers and larger dogs, gentle socialization and a well-fitted harness help. Chihuahuas and Chihuahua mixes are among the most common small dogs in US shelters, so adults of many ages and personalities are often waiting for homes.
