What a Cavalier King Charles Spaniel really costs

Cavaliers are easy keepers day to day, with modest food and grooming bills, but they carry one of the heaviest predictable vet bills of any small breed: nearly every Cavalier develops mitral valve disease, often in middle age. Budget for annual heart checks from youth and years of cardiac medication later in life.

Size: Small, 13–18 lb
Life expectancy: 12–15 years
Grooming: Moderate
Insurance risk: High
Puppy price: $2,500–$3,500
Food a day: About 480 calories

Where the money goes each year

A typical adult year for a Cavalier King Charles Spaniel with mainstream food, a groomer, no insurance, in an average-cost area. That's $210 less than the median breed.

Illness and injury (average)$902
Dental cleanings$425
Heartworm, flea and tick prevention$404
Checkups, vaccines and tests$330
Food$251
Grooming$219
Toys, beds and everyday supplies$180
Treats and chews$50
License$20
Typical year$2,780

Most years land between $2,160 (budget food, home grooming, lower-cost area) and $3,880 (premium food, groomer, insurance, big city). Dogs over about 8 add about $180 a year for senior checkups.

Health costs to plan for

Trupanion claim data shows Cavaliers more than ten times as likely as average to claim for mitral valve disease, heart murmurs and syringomyelia, putting them among the costliest small breeds to insure.

Condition	How it affects Cavalier King Charles Spaniels	Typical treatment	Cost
Mitral valve disease (MVD)	In a 2021 echocardiography study, all 126 Cavaliers over age 8 had mitral valve disease, and Trupanion sees Cavaliers more than ten times as often as average for MVD and heart murmur claims. Source	Heart medications once the disease advances, per year ($100–$300 a month), plus echocardiograms (about $250 each at a teaching hospital)	$1,200–$3,600
Syringomyelia (Chiari-like malformation)	Trupanion claim data shows senior Cavaliers are more than ten times as likely as the average dog to have a syringomyelia claim. Source	Average annual cost of a syringomyelia claim (Trupanion claim data); MRI diagnosis adds more	$800–$1,900
Congestive heart failure	Trupanion claim data shows senior Cavaliers are four times as likely as the average dog to have a congestive heart failure claim. Source	Average annual cost of congestive heart failure care (Trupanion claim data)	$900–$1,500
Dental disease	VetCompass found 25.3% of UK Cavaliers had periodontal disease in a single year (odds 2.39 times crossbreds), and Trupanion reports adult Cavaliers 2.5 times as likely to have dental claims. Source	Professional cleaning under anesthesia ($350–$500 routine), rising to $1,500+ with extractions	$350–$1,500
Patellar luxation	Trupanion data shows Cavalier puppies three times as likely as the average dog to have a kneecap claim, though OFA lists only 2.2% of 18,656 screened as abnormal. Source	Surgical correction by a board-certified surgeon, per knee	$1,500–$3,000

The yearly estimate already includes an average allowance of $902 for illness and injury. A single surgery can cost several times that, which is the case for an emergency fund or insurance.

What drives the cost of a Cavalier King Charles Spaniel

Plan for a cardiac exam every year and echocardiograms once a murmur appears; heart medications for an affected dog can cost $100–$300 a month.
Insure early, before a murmur is recorded; once noted, heart disease is usually excluded as pre-existing.
Long, feathered ears trap moisture, so weekly ear checks and cleaning help avoid repeated ear-infection visits.
A professional bath and tidy every couple of months keeps feathering mat-free; most owners do not need full haircuts.
Cavaliers keep a spaniel's chase instinct, so a fenced yard or leash is needed; lost-dog and injury costs are avoidable.

Reputable breeder: $2,500–$3,500
