The Cavalier is a toy spaniel from England, revived in the 1920s after an American enthusiast offered a prize at Crufts for dogs resembling the longer-nosed spaniels in portraits from King Charles II's era. Britain recognized the breed in 1944 and the American Kennel Club in 1995. Adults stand 12 to 13 inches, weigh 13 to 18 pounds, and have long feathered ears and a silky coat in Blenheim, tricolor, ruby or black and tan.
Cavaliers are gentle, sociable and usually friendly with children, other dogs and cats, though each dog varies. That sweetness comes with planning: nearly all Cavaliers eventually develop mitral valve heart disease, and many carry a skull malformation linked to syringomyelia. Moderate shedding and a coat that needs regular brushing round out the care list.
