PetDon't let the size fool you — Chihuahuas are one of the longest-lived dog breeds, and that long life means more years of dental cleanings, more chances for knee or heart issues to appear, and more total lifetime veterinary spend than their size suggests. Here's what Canadian owners should plan for.
Chihuahua at a glance
| Typical adult weight | 1.5–3 kg |
| Height | 15–23 cm at the shoulder |
| Lifespan | 14–18 years (one of the longest-lived breeds) |
| Breed group | Toy |
| Coat & shedding | Smooth or long coat; low to moderate shedding |
| Energy level | Moderate — lively but small, easy to exercise indoors |
| Insurance snapshot | Low to moderate premiums, but a long life means dental, knee and heart claims add up over time |
Common Chihuahua health issues
| Condition | How common | Typical treatment cost (CAD) |
|---|---|---|
| Dental disease (tiny crowded jaw) | Very common — the defining ongoing cost | Moderate per cleaning, recurring; extractions common |
| Patellar luxation | Very common in the breed | Moderate to high if surgical |
| Heart disease (mitral valve) | Common in later life | Lifelong medication; can escalate |
| Tracheal collapse | Notable in toy breeds | Moderate to high; chronic management |
| Hydrocephalus | Breed-associated, especially apple-head type | High — neurological condition |
| Hypoglycemia (especially puppies) | Common in very small/young dogs | Low to moderate; emergency in acute cases |
| Luxating patella–related arthritis | Common with age | Moderate ongoing |
Our Recommendation
For a Chihuahua, comprehensive coverage with a wellness add-on, enrolled early, is the smart structure. The wellness portion offsets the frequent dental care; the comprehensive base catches knee surgery, heart management, and the rarer neurological issues. Because Chihuahuas live so long, a policy started in puppyhood typically delivers value over a 15-year-plus horizon.
What drives a Chihuahua's insurance cost
Don't let the low premium fool you — a Chihuahua's 14–18-year lifespan means the policy gets used for many years. Dental disease (~$650–1,300 per cleaning, often recurring) is the dominant ongoing cost, because a full set of teeth is crowded into the tiniest of jaws. Add patellar luxation (a slipping kneecap, common and sometimes surgical), age-related mitral-valve heart disease (~$50–300/month once it appears), tracheal collapse, and breed-associated hydrocephalus.
How to structure coverage for a Chihuahua
Comprehensive coverage with a wellness add-on, enrolled in puppyhood, is the smart structure — the wellness portion offsets frequent dental care while the comprehensive base catches knee surgery, heart management, and the rarer neurological issues. Because Chihuahuas live so long, a policy started early has a 15-year-plus runway to deliver value, and it locks in coverage before dental or knee problems become pre-existing exclusions.
