The Cavalier King Charles Spaniel is a toy spaniel from England, revived in the 1920s after an American offered prize money for dogs resembling the long-nosed spaniels in portraits of Charles II. The AKC recognized the breed in 1995. Adults weigh about 13 to 18 pounds, with large dark eyes, long feathered ears and a silky coat in Blenheim, tricolor, ruby or black and tan.
Many Cavaliers are gentle, sociable and happy on a lap or a walk, and they often get along with children, other dogs and cats. That sweetness comes with serious health concerns, since nearly all develop mitral valve heart disease eventually, so adopters should plan for veterinary costs. The coat needs regular brushing, and dogs vary in energy and in how strongly they chase birds and squirrels.
