Cavaliers were revived in the 1920s, when American Roswell Eldridge offered a prize at Crufts for toy spaniels like the ones in portraits from King Charles II's era. Britain recognized the Cavalier as its own breed in 1944, and the American Kennel Club followed 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 and affectionate, and they often get along with children, other dogs and cats. The silky coat sheds moderately and needs regular brushing. Their sweetness comes with serious health concerns: nearly all develop mitral valve heart disease eventually, and many have a skull malformation linked to syringomyelia. Each dog varies, but it pays to plan for veterinary costs.
