Cavalier King Charles Spaniel
Summary
The Cavalier King Charles Spaniel is a recreation, developed in the 1920s–1930s, of the old English long-faced Spaniel that appears in 17th-century paintings — prior to the cross with the Pug that gave rise to the modern King Charles Spaniel. It is slightly larger than the King Charles and with a longer muzzle, which results in fewer respiratory problems. It is currently one of the most popular companion breeds in the world due to its exceptionally gentle and adaptable nature.

Cavalier King Charles Spaniel — Frequently Asked Questions
What is the most important health concern for Cavalier King Charles Spaniels?
Mitral Valve Disease (MVD) is the defining health challenge of the breed — the vast majority of Cavaliers will develop this heart condition by the age of 10, and many develop it much earlier. It's a progressive condition that eventually leads to heart failure. Regular cardiac check-ups with a cardiologist from age one, buying from breeders who follow the Cavalier Health heart-screening protocol, and early treatment when a murmur is detected all make a genuine difference to quality and length of life.
Are Cavalier King Charles Spaniels good apartment dogs?
Cavaliers are among the best apartment breeds available — they're small, quiet, calm indoors, and perfectly happy with moderate exercise. They adore being close to their person and won't demand hours of strenuous activity. Their gentle, adaptable nature means they settle into apartment routines easily, as long as they get a couple of short-to-moderate walks per day and lots of cuddle time.
Do Cavaliers suffer from separation anxiety?
Cavaliers are bred to be companion dogs and can struggle significantly with being left alone — they thrive on human contact and may bark, pace, or become destructive when isolated. Gradual alone-time training from puppyhood is essential. Some do fine when properly trained, while others benefit from a companion dog or dog walker during the day. This breed is truly best suited to households where someone is home for most of the day.
What is syringomyelia in Cavaliers, and should I worry about it?
Syringomyelia (SM) is a painful neurological condition caused by the Cavalier's skull being too small for its brain — fluid-filled cavities form in the spinal cord, causing scratching, sensitivity to touch, and pain. It's unfortunately common in the breed. MRI screening of breeding parents and choosing breeders who test for both MVD and SM gives the best chance of a healthier puppy. Any Cavalier showing symptoms (especially phantom scratching) should see a neurologist promptly.
Are Cavaliers easy to train?
Cavaliers are gentle, people-pleasing dogs that respond beautifully to positive reinforcement — they genuinely want to make you happy. They're not as laser-focused as a Border Collie, but they learn basic obedience readily and enjoy trick training as a bonding activity. Their sensitive nature means they shut down completely under pressure, so calm, patient, reward-based training is the only approach that works well with them.
How much exercise does a Cavalier need?
Cavaliers are moderate exercisers — they enjoy and need around 30–45 minutes of daily walking and enjoy off-leash play when safe. They're adaptable and happy to join you on longer hikes occasionally, but don't require intense workouts. Be mindful of temperature as their spaniel faces can make them more sensitive to heat than most dogs. A comfortable walk in the morning and evening suits most Cavaliers perfectly.
Are Cavaliers good family dogs?
Cavaliers are superb family dogs — gentle, patient, and delighted to be involved in family life. They're soft-natured enough to be safe around very young children and adaptable enough to fit into most family routines. They do best in families where they won't be left alone for long hours, as their companion breed nature means they genuinely need human presence to be content. Given that, they repay with unconditional love and joyful companionship.
How long do Cavalier King Charles Spaniels typically live?
Cavaliers typically live 9–14 years, though the cardiac disease burden means many live closer to the lower end of that range. With early heart-screening, prompt treatment of MVD when detected, and proper general care, many Cavaliers live well into their early-to-mid teens. Choosing puppies from health-screened parents is one of the single most impactful decisions you can make for a long and comfortable life together.
