The short answer
Cavaliers are the breed where the breeder price tag is the cheapest part of ownership. A $4,000 puppy is the small line on the lifetime spreadsheet. Mitral valve disease (MVD) shows up in roughly 50% of Cavaliers by age 5 and nearly all by age 10. Heart medications, echocardiograms, and cardiac specialist visits then drive monthly cost from $130 to $450+. The Reddit Cavalier community has multiple documented cases of one dog running up $25,000 to $42,000 in vet bills for one condition alone. Read the medical-cost math below before you adopt, then decide. The breed is gentle, kid-friendly, and worth it for the right home. The wrong call here is buying on price and learning the medical reality later.

Monthly Budget by Health Scenario
| Monthly Expense | Healthy | MVD | SM | Both |
|---|---|---|---|---|
| Food | $30 to $50 | $30 to $50 | $30 to $50 | $30 to $50 |
| Pet insurance | $35 to $70 | $60 to $110 | $60 to $110 | $90 to $150 |
| Baseline vet (averaged) | $30 to $60 | $50 to $100 | $50 to $100 | $60 to $120 |
| Grooming (averaged) | $40 to $70 | $40 to $70 | $40 to $70 | $40 to $70 |
| Heart medications | $0 | $50 to $150 | $0 | $50 to $150 |
| SM medications (gabapentin, omeprazole) | $0 | $0 | $40 to $120 | $40 to $120 |
| Cardiac specialist (averaged) | $0 | $50 to $100 | $0 | $50 to $100 |
| Enrichment / treats | $20 to $40 | $20 to $40 | $20 to $40 | $20 to $40 |
| Monthly total | $155 to $290 | $300 to $620 | $240 to $490 | $380 to $800 |
| Add: Daycare 1 day/wk (if WFT) | +$140 to $220 | +$140 to $220 | +$140 to $220 | +$140 to $220 |
Most Calgary Cavaliers move from the healthy column into the MVD column between ages 5 and 7. About 10 to 20% of Cavaliers show clinical syringomyelia symptoms. Plan budget around the MVD column, not the healthy one.
Annual + Lifetime Totals (with Real Reddit Case Studies)
Best case (late-onset MVD)
Annual: $1,500 to $2,500 healthy years, $3,000 to $5,000 senior years
Lifetime over 12 to 14 years: $25,000 to $45,000
Lucky genetic draw. MVD onset after age 8. No SM. Manageable senior cardiac care for the last 3 to 5 years. Roughly 15 to 20% of Cavaliers land here.
Average case (typical MVD)
Annual: $3,000 to $5,000 with full MVD progression
Lifetime over 10 to 12 years: $45,000 to $70,000
MVD diagnosed age 5 to 7. Steady cardiac care, heart meds, annual echos for 5 to 8 years. The most common path. Roughly 60 to 65% of Calgary Cavaliers fall here. Reddit case study: one owner reported $25,000 in vet bills over 2 years managing late-stage MVD.
High medical (MVD + SM)
Annual: $5,000 to $8,000+ with both conditions
Lifetime over 9 to 11 years: $70,000 to $100,000+
Early MVD plus clinical SM plus possible decompression surgery. Roughly 15 to 20% of Cavaliers. Insurance bought early is essential here. Reddit case study: one owner documented $42,000 in vet bills over 3 years for SM management alone, before any cardiac costs.

Adoption fees $300 to $700 vs $3,000 to $8,000+ breeder pricing. Rescue Cavaliers come with spay/neuter, vaccines, microchip, and vet workup included. Some are seniors with known MVD status, which is actually useful information for budgeting.

Major Medical Costs (Calgary 2026)
| Procedure / Care | Calgary cost | Lifetime probability |
|---|---|---|
| Diagnostic echocardiogram | $400 to $700 per visit | ~98% by age 10 (recurring every 6-12 mo once positive) |
| Heart medications (pimobendan, enalapril, furosemide) | $50 to $150/month | ~95% (lifelong once started) |
| Cardiac specialist consult | $200 to $500 per visit | ~95% (annual once diagnosed) |
| MRI for SM diagnosis | $1,500 to $3,000 per scan | ~15 to 25% (recurring if symptoms progress) |
| Decompression surgery (Chiari-like malformation) | $8,000 to $15,000 | ~3 to 5% |
| Dental cleaning + extractions | $500 to $1,500 per visit | ~90% (recurring every 1-2 years) |
| Patellar luxation repair | $2,500 to $4,500 per knee | ~10 to 15% |
Calgary specialty centres: Western Veterinary Specialist & Emergency Centre, Calgary North Veterinary Hospital, Veterinary Specialists of Western Canada. Cavaliers with documented health-tested parents (heart-clear sire and dam, MRI-cleared) have lower SM probability but the MVD numbers stay high regardless of breeding.
Hidden Costs Owners Did Not Plan For
1. Cardiac specialist visits
$200 to $500 per visit. Most Cavaliers need 1 to 2 specialist visits per year once a murmur shows up, plus the echos. The cardiologist appointment alone runs more per visit than a year of GP wellness care for most other small breeds.
2. Daycare or dog walker
Calgary daycare $35 to $55/day. Walker $25 to $40/visit. One daycare day a week runs $140 to $220/month. Cavaliers are velcro dogs and separation anxiety surfaces fast if left alone all day. Most owners working full-time end up paying for at least one daycare day to prevent it.
3. Training classes
$200 to $400 per round at Calgary force-free schools like Raising Canine or The Calgary Animal Referral and Emergency Centre training program. Most owners do two to three rounds in the first two years (puppy class plus one or two follow-on classes).
4. Calgary winter gear
$80 to $150 for a sweater, booties, and paw wax. Cavaliers have a thin coat and low cold tolerance and need real winter gear below minus 10. Most owners replace gear every 2 to 3 years.
5. Home grooming equipment
Slicker brush, steel comb, blow dryer, dematting tool, ear cleaner, scissors. Setup is $100 to $200. Cavaliers have feathered ears, legs, and tail that mat quickly without daily brushing between professional groomer visits.
6. MRI imaging if SM symptoms appear
$1,500 to $3,000 per scan. If your Cavalier shows scratching at the air, neck pain, or yelping for no reason between ages 1 and 4, an MRI is the diagnostic standard. Some dogs need repeat imaging if symptoms progress. Insurance bought before symptoms typically covers this; pre-existing exclusion is the trap.
The honest pre-adoption reserve
Calgary vets and rescues recommend a pre-adoption reserve of $5,000 to $8,000 minimum for Cavalier ownership. Breakdown: adoption fee + setup + first-year vet + first-year insurance + emergency buffer. The buffer is bigger than for most small breeds because MVD is not a question of if but when.
If a $5,000 to $8,000 unexpected vet bill would create real financial stress, this is probably not the right time of life for a Cavalier. Medical-cost overwhelm is one of the most common reasons we see Cavaliers hit Calgary rescues. Plan for it, or wait until you can. Read our Cavalier health issues guide before deciding.
