Your Cavalier's first year — a health-first guide
Cavaliers are among the most affectionate breeds ever created — sweet, gentle, and bonded to their people. They're also at the sharp end of breed-related health issues: mitral valve disease affects most Cavaliers by age 10; syringomyelia affects up to 70%. The right breeder makes the single biggest difference.
Companion-focused owners with time for daily affection and moderate walks
Owners away all day (they develop separation distress) or budget-constrained homes (health screening is essential)
Month-by-month timeline
Look for AKC-registered or reputable breeders with heart-certified parents (current MVD cert) and MRI-scanned parents for syringomyelia. Walking away from un-screened breeders saves thousands in vet bills.
First jabs at 8 weeks. Cavaliers are sensitive — keep first days calm and predictable. Soft crate or pen.
Second jabs at 10–12 weeks. Expose to varied people, dogs, surfaces. Cavaliers are naturally friendly — easy to over-socialize them into thinking every dog is a friend.
Build tolerance for being alone from week one. Cavaliers are prone to separation anxiety — short absences, gradually extended.
Eager to please + food-motivated = fast learners. Short positive sessions.
Ask your vet to listen to the heart at check-ups. Early murmurs may be detectable. MVD is genetic and typically develops in middle age but baseline now helps.
Some Cavaliers chase — their Spaniel ancestry surfaces. Build recall early, use long-line in unfenced areas.
Milder teen phase than many breeds. Consistency wins.
Later is typically better (15–18 months for skeletal maturity). Discuss with vet.
Cavaliers gain weight easily. Every extra kilo stresses a mitral-valve-prone heart.
Floppy ears need weekly cleaning. Watch for bulging/teary eyes (brachycephalic tendencies exist in some Cavaliers).
Full vet check, booster, weight, heart listen, neurology basics (unexplained scratching/yelping?). Schedule a specialist cardiac scan from age 3–4.
Feeding
Easy keepers — they gain weight on small portions. A Cavalier that looks "cute and round" is usually overweight.
- Weigh food daily. A Cavalier's adult portion is smaller than you'd guess.
- Two meals a day from 6 months.
- Training treats break down from daily allowance.
- Watch for begging — they're Olympic-level manipulators and people cave fast.
- Ears in bowls is a common issue — raised-sided bowls or snoods help.
Training priorities
- Alone-time tolerance — most important training goal
- Handling (ears, paws, belly)
- Settle on mat — Cavaliers want to be with you; settle teaches them to relax alone
- Recall — for the day off-leash becomes safe
- Loose-leash walking — usually easy for Cavaliers
- No jumping up — their backs aren't as vulnerable as Dachshunds but jumping on furniture still adds up
Health watch-outs
The #1 Cavalier health issue. Breeding parents should be heart-certified each year. Annual cardiac exams from age 3. Very high lifetime prevalence.
Up to 70% affected. Causes air-scratching, yelping when touched, neck pain. MRI-screened parents reduce risk significantly.
Genetic test available — reputable breeders screen.
Screenable at birth; painful if not diagnosed.
Floppy ears = weekly care.
Worsens every other issue, especially heart.
Exercise
Puppy (under 12 months): 5-minute rule until 12 months. Low to moderate impact.
Adult: 30–60 minutes daily, split. They love gentle walks and happily curl up afterwards.
Grooming
Common first-year mistakes
- Skipping the cardiac-certified / MRI-scanned breeder question. It's the difference between typical and catastrophic lifetime costs.
- Letting them fatten up as puppies. Cute rolls at 6 months = chronic weight issues at 3.
- Leaving them alone too long. Separation anxiety escalates quickly.
- Ignoring "air scratching" or phantom scratching. Often a symptom of syringomyelia — needs neurology referral.
- Not insuring from day one. Breed-associated conditions can be excluded if diagnosed before cover.
Frequently asked
Are Cavalier puppies healthy?
Individual puppies can be very healthy, but the breed has high rates of specific genetic conditions. Health-screened parents (MVD cert + MRI for SM) drastically improve odds but don't eliminate risk.
How much exercise does a Cavalier need?
30–60 minutes daily as adults. They're flexible — happy with a short walk or a long one. Mental enrichment matters too.
Are Cavaliers good family dogs?
Excellent — gentle, patient, and sociable. They bond strongly with their family and get on with children, other dogs, and cats. Watch energy-level mismatches with very active kids (they're happy to lounge).
Do Cavaliers shed a lot?
Moderate year-round shedding. Not a hypoallergenic breed despite the silky coat.
How much does a Cavalier cost in year one?
$1,800–$3,500 (puppy $1,500–$2,800 from reputable breeder, food $250–$400, insurance $300–$500 — tends to rise as heart conditions emerge, kit $200–$400, grooming $400–$600).
