The Cavalier King Charles Spaniel is an active, graceful, well-balanced toy spaniel, very gay and free in action; fearless and sporting in character, yet at the same time gentle and affectionate. It is this typical gay temperament, combined with true elegance and royal appearance which are of paramount importance in the breed. Natural appearance with no trimming, sculpting or artificial alteration is essential to breed type.
Cavaliers have been depicted in many famous paintings throughout history, usually with royalty. King Charles II made the Cavalier popular during his reign, and set the breed standard for the time.
