Health problems linked to the Cavalier King Charles Spaniel

Conditions and what they can cost
ConditionWhat it isRelated costs
Hip dysplasiaNamed by: AKC breed page, breed club screening [1]The hip joint forms loosely, so the ball and socket rub and wear. Over time this usually leads to arthritis and pain. [2]Hip surgery (owner bills): $2,500–$5,500 (estimate) [3]
Ongoing arthritis care: $500–$2,500 total [4]
Luxating patella (slipping kneecap)Named by: AKC breed page, breed club screening [1]The kneecap slips out of its groove. Mild cases may only cause an odd skip in the step; severe cases can need surgery. [5]Surgery, median invoice: $1,284 (typical $578–$3,229) [6]
Dog X-rays (owner bills): $130–$300 [7]
CataractsNamed by: AKC breed page [1]The lens of the eye turns cloudy and vision fades. Some cataracts can be removed surgically by a veterinary eye specialist. [8]Sick visit (owner bills): $160–$525 [9]
Surgery, median invoice: $1,284 (typical $578–$3,229) [6]
Mitral valve diseaseNamed by: AKC breed page [1]A heart valve thickens and leaks. It often starts as a murmur and can lead to heart failure in older dogs. [10]Dog ultrasound (owner bills): $80–$500 [11]
Ear infectionsNamed by: AKC breed page [1]Floppy or hairy ears trap moisture, which makes infections more likely. Regular cleaning helps, and repeat infections often point to allergies. [12]Ear infection treatment (owner bills): $200–$650 [13]
Syringomyelia (Chiari-like malformation)Named by: AKC breed page [1]The skull is too small for the brain, which can cause fluid pockets in the spinal cord. Signs include neck pain and scratching at the air. [14]Dog MRI (owner bills): $900–$2,900 [15]

Costs are national figures from our sourced cost guides, not breed-specific prices. Being on this list doesn't mean a pet will get the condition.

Here is how the AKC breed page puts it: These include certain eye conditions (including retinal problems and cataracts), patella luxation, hip dysplasia, middle ear infections, mitral valve heart disease, and a neurological condition called syringomyelia. [1]

Health screening

The national breed club recommends these health tests for breeding dogs: Patella Evaluation, Hip Evaluation, Cardiac Exam, Ophthalmologist Evaluation. [1][16] If you are buying a puppy, it is fair to ask the breeder for the parents' results. OFA keeps a public database of many of them.

The UC Davis Veterinary Genetics Laboratory lists 1 DNA health test for the Cavalier King Charles Spaniel, including Progressive Rod-Cone Degeneration (PRA-prcd). [17] One health test costs $58 there. [18]

What to budget

For a small dog like the Cavalier King Charles Spaniel, a typical vet bill runs $273 – $1,110 (median $508), and surgery, when needed, runs $435 – $1,484. [19]

Lifetime cost, roughly. Our yearly estimate for an adult Cavalier King Charles Spaniel at US-average prices, before insurance, is $880–$1,400. Multiply that by a life expectancy of 12–15 years and you get roughly $10,500–$20,700 over a lifetime, before inflation and before any major illness. The low end is the ASPCA's yearly cost of care; the high end adds one typical vet bill a year. [19][20] It's simple math on sourced figures, not a quote.

Insurance and savings

The average accident and illness policy cost $836 a year for a dog in the US in 2025. [21] Timing matters more than the price. A condition that shows up before you enroll is usually treated as pre-existing and isn't covered. [22] Many plans also have a 6 to 12 month waiting period for orthopedic problems like knees and hips. [23]

Prefer saving instead? Putting money aside each month works too; see insurance vs a savings fund.
