Question 1

Is a Cavalier King Charles Spaniel or Cocker Spaniel more expensive to own?

Accepted Answer

Cavalier King Charles Spaniels are more expensive to own due to serious breed-specific heart disease. Nearly all Cavaliers develop mitral valve disease (MVD) by age 10 — it's the leading cause of death in the breed. Cardiac medication and cardiologist monitoring can cost $2,000–$5,000/year in later life. Purchase price: $1,500–$3,500 for a Cavalier vs $800–$2,500 for a Cocker Spaniel. Lifetime cost: $28,000–$45,000 for a Cavalier vs $20,000–$30,000 for a Cocker.

Question 2

What heart problems do Cavalier King Charles Spaniels have?

Accepted Answer

Mitral valve disease (MVD) is near-universal in Cavaliers. Studies show 50% of Cavaliers have heart murmurs by age 5, and nearly all by age 10. MVD is progressive — dogs move from a murmur to heart failure over months or years. Management involves medications (pimobendan, ACE inhibitors, furosemide) that cost $100–$300/month in late-stage heart failure. Cardiologist visits run $200–$400 per exam. The MVD Health Protocol recommends screening breeding dogs annually — ask for cardiology certificates before buying.

Question 3

What health problems do Cocker Spaniels have?

Accepted Answer

Cocker Spaniels (American or English) are prone to ear infections (their long, floppy ears trap moisture), eye conditions (cataracts, glaucoma), hip dysplasia, and autoimmune conditions. Ear infections are the most common recurring cost — plan $100–$300/year for cleaning and treatment. Cocker Spaniels can also develop AIHA (autoimmune hemolytic anemia), which is serious but less universal than Cavalier heart disease. Overall health costs are lower than Cavaliers but higher than average for a small breed.

Question 4

How much does it cost to groom a Cavalier vs a Cocker Spaniel?

Accepted Answer

Both breeds need regular professional grooming. Cavaliers have silky medium-length coats that need grooming every 8–10 weeks ($60–$100/session). Cocker Spaniels have thicker coats that require grooming every 6–8 weeks and more complex clipping ($75–$120/session). Annual grooming: $500–$900 for a Cavalier, $600–$1,100 for a Cocker Spaniel. Both breeds also require regular ear cleaning — floppy-eared breeds need weekly ear checks to prevent infections.

Question 5

Are Cavaliers or Cocker Spaniels better apartment dogs?

Accepted Answer

Both breeds do well in apartments. Cavaliers are especially suited — they're calm, adaptable, and happy with moderate exercise (30–45 min/day). Cocker Spaniels are slightly more energetic and need 45–60 min of daily exercise. Neither breed is excessive in size or noise. The bigger apartment consideration is the Cavalier's health needs: regular cardiac checkups require a nearby veterinary cardiologist, which is easier to find in cities than rural areas.
