Common Misconceptions about the Cavalier King Charles Spaniel
That a healthy-looking Cavalier puppy is enough. Heart disease and syringomyelia can develop later, so parental clearances matter. Another misconception is that Cavaliers and King Charles Spaniels are the same; in the US, the flatter-faced King Charles is a separate breed called the English Toy Spaniel.

Cavalier King Charles Spaniel Health
Common Health Issues
Mitral valve disease, syringomyelia, patellar luxation
Diet & Nutrition
Feed a quality small-breed diet in measured portions; Cavaliers love food and gain weight easily, which puts extra strain on the heart. Choose small training treats. Talk to your vet before choosing grain-free or boutique diets, given the breed's heart risks.
Health Care
Health research is essential before buying a Cavalier. Mitral valve disease (MVD) affects most Cavaliers eventually, and often starts early. Ask breeders to show heart clearances from a cardiologist for both parents, and ideally follow MVD breeding protocols that use parents and grandparents with heart-clear results at specific ages. Syringomyelia, a condition in which fluid-filled cavities form in the spinal cord, is also common; signs include scratching at the neck or shoulder without contact (phantom scratching), sensitivity to touch, and pain. MRI screening of breeding dogs helps. Ask about DNA tests for episodic falling and curly coat/dry eye syndrome, plus eye, hip, and knee evaluations.
About the Cavalier King Charles Spaniel
History
Small spaniels were favorites of the British aristocracy for centuries, and King Charles II was so attached to his that the dogs took his name. Over time, breeders favored flatter faces and domed heads, creating the type now known in the US as the English Toy Spaniel. In the 1920s, an American named Roswell Eldridge offered prize money at Crufts for spaniels resembling the old paintings, with longer noses and flat skulls. Breeders took up the challenge, and the Cavalier King Charles Spaniel was born from that effort. The Kennel Club recognized it as a separate breed in 1945, and the AKC recognized it in 1995.
Personality
Cavaliers are among the most gentle and affectionate breeds. They want to be with their people and usually like strangers, children, and other dogs just as much. They are adaptable: happy to snuggle on the couch or go for a hike. They have some sporting spaniel instincts and may chase birds or squirrels, so a secure leash and fence matter. They are not watchdogs, and most bark only occasionally. Their sensitivity is a strength and a weakness: they respond beautifully to gentle training but can become anxious if left alone for long periods. They are an ideal companion for people who are home a lot and want a sweet, sociable dog.
Living With a Cavalier King Charles Spaniel
Cavaliers adapt well to apartments or houses, cities or countryside, as long as they get companionship and moderate exercise. Daily walks and play keep them fit. They do best when someone is home much of the day, since many struggle with separation. They usually get along well with children, other dogs, and cats. Keep them leashed or in a fenced area because they may chase birds and squirrels.
Training
Cavaliers are eager to please and respond well to gentle, reward-based training. They pick up house rules quickly and enjoy tricks, rally, and therapy-dog work. Build confidence with short periods alone from puppyhood to prevent separation anxiety. Practice recall in safe areas, since their chasing instinct can override it.
