About
What is a Cavalier King Charles Spaniel?
Small, elegant toy spaniel with silky coat, large expressive eyes, and noble appearance, known for its gentle expression and affectionate temperament, equally at home as a lap dog or active companion
Cavalier King Charles Spaniel history and origins
Named after King Charles II who favored the breed, descended from toy spaniels depicted in 16th-18th century British court paintings. The modern breed was revived in the 1920s by enthusiasts seeking to restore the longer-nosed type seen in old portraits
Cavalier King Charles Spaniel appearance and size
Typically 6-8 kg and 30-33 cm at the shoulder — published as one range rather than separately for males and females.

What you are taking on

- High grooming needs — the standard’s own description is “Plenty of feathering. Totally free from trimming”
Drawn from sources rather than written as an opinion — cited health research, the registry’s own standard, and peer-reviewed longevity.

One breeder’s animals can differ from any of it, and an empty column means we hold nothing for that side rather than that there is nothing to say.

Shortened from FCI standard n°136 — each label is the standard’s own wording with the verdict lifted into the tag beside it. Read the full clause at source.
FCI varieties
FCI divides the Cavalier King Charles Spaniel into these varieties, listed in the registry's own words. Depending on the breed they separate colour, coat, size or line — they are not a full list of colours, which no registry we hold publishes. Ask a breeder which variety their line is.

5 conditions documentedThis is breed-level literature, not veterinary advice about an individual animal — your vet knows the animal.
Health checklist (PDF)Heart & circulation
Mitral valve disease (MVD)
Serious
Degeneration of the mitral heart valve leading to a leaking murmur, and in many dogs eventually to congestive heart failure; it appears earlier and far more often in this breed than in any other. There are no recognised varieties in this breed, so this applies breed-wide.
What to ask for
A current cardiac auscultation result from a boarded veterinary cardiologist for both parents, following the age-linked MVD breeding protocol (clear of a murmur past 2.5 years, ideally with parents and grandparents clear at 5)
Bones & joints
Chondrodystrophy-linked intervertebral disc disease (IVDD)
Serious
A raised risk of premature disc degeneration from the same FGF4 retrogene insertion (CDDY) implicated in Dachshunds; testing-lab data show it at very high frequency in this breed (allele frequency around 99.6%), and a 2025 study of 43,517 US dogs found Cavaliers at four times the odds of owner-reported IVDD compared with mixed-breed dogs.
What to ask for
A CDDY/IVDD-risk DNA test on both parents
Brain & nerves
Chiari-like malformation and syringomyelia (CM/SM)
SeriousInherent to the breed
A mismatch between the skull and brain causes fluid-filled cavities to form in the spinal cord, producing neck pain, scratching at the neck/shoulder without contact, and in severe cases partial paralysis. The Kennel Club and British Veterinary Association run a dedicated joint screening scheme for this breed because of how closely it relates to the breed's skull conformation.
What to ask for
An MRI grading under the BVA/Kennel Club Chiari-like Malformation and Syringomyelia scheme for both parents
Episodic falling syndrome (EFS)
Serious
An inherited disorder of muscle control, usually appearing in the first year of life, in which exercise, excitement or frustration triggers rigid muscles and collapse. A DNA test has existed since the causal mutation was identified, so no dog need be bred that can produce an affected puppy.
What to ask for
An episodic falling syndrome DNA test on both parents
Eyes
Curly coat / dry eye syndrome
Serious
An inherited disorder in which affected dogs produce no tears, leaving the eyes chronically sore, alongside dry, flaky skin that can make standing and walking painful.
What to ask for
A curly coat/dry eye syndrome DNA test on both parents
How long the Cavalier King Charles Spaniel lives, in the records
Median survival 11,8 years
95% confidence interval 11,7–11,9 years, from 6879 recorded deaths among 13.866 dogs
Mortality hazard 1.07 (1.04, 1.09) relative to crossbred dogs, whose median is 12,0 years.
Measured in the United Kingdom from 584.734 dogs. Median survival is not a prediction for an individual dog.
