"Adopt Billy, an 11-year-old longhaired Chihuahua mix! Billy is extremely smart and he loves to learn new tricks and go for long walks. Billy will do best in a quieter family who can help him get comfortable with new people. Once Billy knows you're his friend, he will want to always be by your side. He's a one-person kind of pup looking for that very special someone. Could it be you?"
