Cavalier King Charles Spaniel Puppies for Sale & Breed Guide

Breed Origin & History

The Cavalier King Charles Spaniel traces back to the small toy spaniels portrayed in 17th century European court paintings by artists such as Van Dyck and Gainsborough. King Charles II of England was so devoted to these little spaniels that they were named for him. They remained a staple of English aristocratic life for centuries. During the Victorian era, however, fashion shifted, breeders refined these toy spaniels into a much shorter muzzled, domed skulled dog that became the English Toy Spaniel (known in the US as the King Charles Spaniel).

The modern Cavalier was effectively recreated in the 1920s when American breeder Roswell Eldridge offered a cash prize at Crufts for any breeder who could produce a toy spaniel resembling the longer muzzled "old type" seen in the Van Dyck paintings. Within a decade a separate breeding program, rebuilt from surviving specimens that still carried the old look, produced what became the Cavalier King Charles Spaniel, distinct from the shorter faced King Charles Spaniel. The Kennel Club (UK) recognized the breed in 1945 and the AKC in 1995.

Because the modern Cavalier was rebuilt from a very small foundation stock in a short window of time, the gene pool is narrower than the breed's popularity would suggest. This narrow foundation is the structural reason for the breed's well documented health burden, not the fault of any individual breeder, but a population genetics challenge that ethical breeders work against every day.

Temperament & Personality

Cavaliers are, in temperament, the archetype of a sweet natured companion dog. They are affectionate, gentle, sociable with nearly everyone and everything, and almost never aggressive. They love children, tolerate other dogs, get along with cats, and greet strangers as long lost friends. The breed has almost no guarding instinct, moderate prey drive (spaniel enough to chase a squirrel but not to hunt seriously), and a deep need for human companionship.

They are trainable, moderately so. Cavaliers are people pleasers but they are not a working breed. They have neither the intense focus of a retriever nor the stubborn independence of a terrier. They learn basic manners quickly with positive methods, make excellent therapy dogs, and do well in rally and beginner obedience. They are less suited to high drive sport or to rigorous protection / service work.

Cavaliers are velcro dogs, even more so than most companion breeds. They want to be on their person at all times. They are not a breed that does well left alone for long hours, and separation anxiety is common when they are. For owners who work from home, are retired, or can bring the dog with them regularly, this deep bond is the breed's greatest gift; for households where the dog will be alone 10 hours a day, the breed is genuinely the wrong choice.

Physical Characteristics

The AKC breed standard recognizes four colors: Blenheim (chestnut on pearly white), Tricolor (black and white with tan markings), Ruby (solid rich red), and Black & Tan. Cavaliers should weigh 13-18 pounds as adults and stand roughly 12-13 inches at the shoulder. "Teacup" or "toy" Cavaliers are not a recognized variety, undersized dogs are typically runts of the litter or the result of deliberately breeding for miniaturization, which concentrates rather than dilutes the breed's genetic risks.

The long, silky feathering on the ears, chest, legs, and tail is defining but demanding. Without regular brushing the feathering mats quickly, especially behind the ears where moisture gathers. Cavaliers are also prone to ear infections due to the heavy pendant ear structure, ear hygiene should be a weekly routine from puppyhood.

Health Testing Requirements

The American Cavalier King Charles Spaniel Club (ACKCSC) participates in the OFA CHIC program. For a Cavalier to earn a CHIC number, the parent club requires the following on both sire and dam before breeding:

Review every OFA, CAER, or MRI claim at ofa.org/look up a dog. If a Cavalier breeder does not know what "MVD Breeding Protocol" or "CM/SM MRI" means, this is not a breeder who should be placing puppies.

Training & Exercise Needs

Cavaliers need 30-60 minutes of daily activity, most of it gentle and low impact. The breed enjoys leashed walks, moderate off leash time in a safe area, and indoor play. They are not a jogging or long hike breed for their first year or for seniors with cardiac disease, but healthy adults can handle a steady walk of several miles. Owners should watch for any sudden reluctance to exercise, coughing after activity, or fainting, these are cardiac warning signs that warrant a cardiologist visit.

Training difficulty is low. Cavaliers are eager to please, food motivated, and sensitive. Short, positive, low pressure sessions work best. The breed does not respond well to harsh methods, they will shut down rather than comply. House training can be slightly slower than average for a small breed but is easily managed with consistent schedule and crate training.

Common behavioral challenges are mostly related to separation (the breed's greatest weakness is being left alone), occasional chasing of birds or small wildlife (the spaniel heritage showing through), and the occasional Cavalier who becomes overly protective of its primary person in a single person household. None are difficult to manage in a home that respects the breed's emotional needs.

Who This Breed Is Best For

• Companions for retired, semi retired, or work from home owners who can have the dog with them most of the day.
• Therapy and emotional support work, few breeds rival the Cavalier for this role.
• Families with children old enough to handle a small dog gently, typically age 6 and up.
• Multi pet households, Cavaliers mix peacefully with other dogs and cats.
• Apartment and small home dwellers who want a calm, affectionate companion.

The Cavalier is a poor match for: households gone long hours every day, owners unwilling or unable to budget for cardiology and neurology care, people who want a high energy sport or working prospect, or anyone shopping primarily on price, the breed's health burden makes cutting corners on breeder selection a long term financial and emotional mistake.

Red Flags When Buying

Walk away from any seller who: markets "teacup" or "toy" Cavaliers; cannot discuss the MVD breeding protocol in detail; breeds multiple breeds or "Cavapoos" and "Cavachons" alongside purebreds; offers puppies before 10 weeks of age (the breed's small size and health complexity warrant a later placement than average); has no cardiologist report less than 12 months old on both parents; refuses MRI discussion; or ships without meeting. Also avoid any Cavalier priced dramatically below market, the breed's health testing requirements make genuinely low cost ethical breeding mathematically impossible.

The Cavalier is heavily produced by commercial breeders because it is small, sells easily, and demand exceeds ethical supply. A commercially bred Cavalier is almost always a cardiology problem waiting to happen. Buyers must be willing to wait, ethical breeders frequently have multi year waitlists and deliberately breed infrequently.

Price Range & Rescue Alternatives

Ethically bred Cavalier King Charles Spaniel puppies from fully health tested parents (including MRI screening and age appropriate cardiac clearances) typically fall in the $3,000–$5,500 range in the United States. Imported or show prospect puppies occasionally higher. Puppies priced below roughly $2,000 are almost universally from programs skipping MRI, cardiac protocol, or both.

Cavalier rescue is smaller than rescue for more populous breeds but is well organized:

• Cavalier Rescue USA, national Cavalier specific rescue network.
• Lucky Star Cavalier Rescue, ACKCSC Rescue Trust, Cavaliers of the NW, regional and parent club programs.
• Breed Adjacent Rescue, many toy breed rescues regularly take in Cavaliers and King Charles Spaniels surrendered by owners who couldn't afford cardiac care.

Adult Cavaliers in rescue are often surrendered because of owner hardship rather than behavior problems, and many are healthy, well socialized, and eager to bond with a new family. For an owner who can provide a steady home and ongoing cardiology monitoring, an adult rescue Cavalier is a wonderful option.

About these recommendations. PuppyReports surfaces the basic health screening recommendations for each breed in accordance with the principles established by the Orthopedic Foundation for Animals (OFA) Canine Health Information Center (CHIC) program. The OFA, working with each breed’s primary US parent club, sets the recommended testing list per breed. Recommendations may vary by country and region (US OFA CHIC, European FCI, UK Kennel Club, Australian National Kennel Council, etc.). Always review current requirements with your breed’s parent club for your jurisdiction. Last reviewed: 2026-05-02.
