QUIZ matches me with Cavalier King Charles Spaniel 92% match The cav is an elegant, royal, toy spaniel, slightly longer than tall, with moderate bone. It retains the build of a working spaniel, yet in a smaller version. Its gait is free and elegant, with good reach and drive. Its silky coat is of moderate length, with a slight wave permissible. Long feathering on the feet is a breed characteristic. A hallmark of the breed is its gentle, sweet, melting expression.
