Cavalier King Charles Spaniel Health Issues: What to Watch For

Mitral valve disease (MVD)

nearly 100% of breed

Virtually every Cavalier develops a heart murmur. By age 5, over 50% have it. By age 10, nearly all do. Medication manages symptoms but doesn't cure it. Surgery ($20K-$40K) exists but is rare.

Treatment cost: $500-$5,000

Syringomyelia (SM)

25-70% of breed

The skull is too small for the brain. Spinal fluid cavities form causing pain, scratching at the air, and neurological symptoms. MRI diagnosis. Pain management or surgery.

Treatment cost: $500-$8,000

Patellar luxation

10-15% of breed

Standard small-breed kneecap issue. Surgery if severe.

Treatment cost: $1,500-$4,000

Ear infections

20-30% of breed

Long, heavy ears with poor air circulation. Chronic recurrence is common.

Treatment cost: $100-$300

Eye conditions (dry eye, cataracts)

10-15% of breed

Keratoconjunctivitis sicca (dry eye) needs lifelong eye drops. Cataracts may need surgical removal.

Treatment cost: $300-$2,000

Recommended Procedures & Screenings

Procedure Frequency Cost
Cardiac auscultation Every 6 months $50-$150
Echocardiogram Annual after murmur detected $300-$600
MRI (if SM symptoms) Once for diagnosis $1,500-$3,000
Dental cleaning Annual $300-$700
Eye exam Annual $50-$150

The Bottom Line on Cavalier King Charles Spaniel Vet Bills

Cavaliers are the most expensive small breed to keep healthy. The heart disease is practically guaranteed — the question is when, not if. Syringomyelia is the second gut-punch: their skull is literally too small for their brain. Insurance with cardiac and neurological coverage is non-negotiable. Despite all this, they're one of the most popular breeds because the temperament is that good.
