Why Your Dog’s Breed Determines What You’ll Pay for Pet Insurance
Mastiff owners pay an average of $2,546 per year for pet insurance. That’s 264% higher than the national average of $700. My friend’s Chihuahua? Insured for about $33 a month — less than her Netflix and Spotify subscriptions combined.
The gap is staggering. If you’re researching breeds or about to bring home a new pup, understanding these costs upfront could save you from some serious sticker shock down the road.
I’ve pulled data from MoneyGeek, Insurify, Pawlicy Advisor, and several insurance providers to break this all down. Let’s get into it.

How Pet Insurance Companies Calculate Breed-Based Premiums
Insurance companies aren’t just randomly assigning prices to different breeds. There’s actual actuarial science behind it, though sometimes the results feel pretty arbitrary when you’re the one writing the check.
The Risk Profiling System
Every breed gets profiled based on historical claim data. Insurers track how often each breed visits the vet, what conditions they develop, and how much those treatments cost. A breed that generates 50% more claims than average? You’re looking at 50-75% higher premiums.
The big factors:
Hereditary conditions — Some breeds are genetic time bombs. Bernese Mountain Dogs have a nearly 50% cancer rate. English Bulldogs need $3,000+ BOAS surgery more often than not. Insurers know this and price accordingly.
Size matters. A lot. Giant breeds like Mastiffs and Great Danes require more anesthesia, larger doses of medication, and more expensive surgical procedures. Everything costs more when your patient weighs 180 pounds.
Lifespan calculations — Shorter-lived breeds often cost MORE to insure, not less. Why? Because they tend to develop expensive conditions earlier, and you’re paying higher premiums for a compressed timeline of potential health issues.
Claim frequency data — French Bulldog owners are six times more likely to file claims for corneal ulceration than owners of non-brachycephalic breeds. Insurers have tracked this stuff for decades.
The Statistical Reality
Dog breeds in the highest risk category can cost 50% to 75% more than breeds insurers consider low risk. And purebreds overall run about 17% higher than mixed breeds ($825 annually versus $687) because mutts benefit from genetic diversity that protects against inherited conditions.
Top 10 Most Expensive Dog Breeds to Insure (With Full Cost Breakdown)
1. Mastiff
At $212 per month and $2,546 annually, Mastiffs top every single “most expensive to insure” list I’ve seen. It’s not even close.
These gentle giants can weigh 230 pounds, and everything about their care scales up accordingly. The issue isn’t just size, though paying for medication dosed by weight adds up fast. Mastiffs are prone to hip dysplasia, gastric torsion (bloat), heart problems, and cancer. A single bloat surgery can run $5,000-$7,500, and without emergency intervention, it’s fatal within hours. Honestly, if you’re bringing home a Mastiff without budgeting at least $200/month for insurance, you’re gambling with money you probably can’t afford to lose.
2. Standard Schnauzer
This one catches people off guard. Standard Schnauzers aren’t giant dogs (typically 35-50 pounds), so why $150/month? Because they’re genetically predisposed to hip dysplasia, eye issues, and pulmonic stenosis, a heart valve defect that can require surgery costing $5,000 or more. At $1,797 annually, that’s 157% above the national average for a medium-sized dog. Those hereditary conditions drive claims through the roof.
3. Bernese Mountain Dog
I had a neighbor with a Berner named Winston. He had two cruciate ligament surgeries before age 5 (totaling about $11,000), and insurance only covered around 60% of it.
That tracks with the data. Berners run $153-293 per month depending on location, and they have one of the highest cancer rates of any breed. The Bernese Mountain Dog Club of America reports that cancer is the leading cause of death in nearly half the breed. They’re also prone to hip and elbow dysplasia, and their average lifespan is just 6-8 years. So yeah, they’re expensive to insure. No mystery there.
4. French Bulldog
Frenchies are everywhere right now (they’ve topped the AKC popularity rankings), but those smushed faces come with a price tag. BOAS treatment averaged $3,174 in 2026, with severe cases requiring multiple surgeries over the dog’s lifetime pushing costs dramatically higher.
What really gets me about Frenchies is the range: $76-181 per month depending on location and provider. That’s a massive spread. A Frenchie in Manhattan might cost you twice what the same dog costs to insure in rural Ohio. Add in spinal issues, skin allergies, and the fact that most Frenchie pregnancies require C-sections, and you start to understand why insurers charge what they do. My advice? If you can’t comfortably budget $150/month for a Frenchie’s insurance, seriously reconsider the breed.
5-7. The Mastiff-Type Trio: Cane Corso, Newfoundland, and Dogue de Bordeaux
I’m grouping these three together because the story is basically the same: big dog, deep chest, bad joints, expensive everything.
Cane Corsos come in at $69/month ($828 annually), which sounds almost reasonable until you realize some insurers also flag them on “restricted breeds” lists due to liability concerns. That can affect both pet and homeowner’s insurance, which is a nasty double hit nobody warns you about.
Newfoundlands are pricier at $70-90/month. Newfies can hit 150 pounds and come loaded with hereditary problems: hip dysplasia, heart valve narrowing (subaortic stenosis), kidney stones, and cystinuria. Cruciate ligament surgery on a dog this size runs $4,000-$6,000. Per knee.
Dogue de Bordeaux — you probably recognize the breed from Turner & Hooch — might be the saddest entry on this list. They have one of the shortest lifespans of any purebred dog (5-8 years) and are riddled with health issues from day one. Hip and elbow dysplasia, heart disease, bloat. Their massive heads mean most puppies are delivered via C-section. At $75-100+ per month, the insurance cost is almost the least of your worries with this breed.
8. Rottweiler
Rottweilers run $70-95/month. The big driver is cancer: the National Canine Cancer Foundation identifies Rottweilers as having significantly elevated cancer risk compared to the general dog population. Heart disease and joint problems pile on top.
Like Cane Corsos, Rotties also land on some insurers’ restricted breed lists, which can bump up rates or limit your options entirely. Worth checking before you commit.
9. Doberman Pinscher
$65-90/month. Dobermans are prone to dilated cardiomyopathy (a serious heart condition), von Willebrand disease (a bleeding disorder), and bloat. That deep chest makes emergency GDV surgery a real possibility. They’re also on some insurers’ restricted breed lists, which can complicate coverage. If you own a Doberman, skip accident-only plans. They’re basically useless for this breed since the expensive stuff is all illness-related.
10. English Bulldog
I’ve talked to three different vets who’ve joked that Bulldogs alone keep the lights on at their practice. Between BOAS, skin fold infections, hip dysplasia, cherry eye, and allergies, these dogs visit the vet constantly. At $80-120/month, insurance premiums reflect that reality.
Most English Bulldogs can’t breed or deliver naturally, they overheat easily, and many can barely breathe properly. The average pet insurance cost for all dog breeds in the UK was £475; Bulldogs cost about double that. I love Bulldogs, but you need to walk in with your eyes open about lifetime costs.
Why These Breeds Cost So Much: A Health Condition Deep Dive
Understanding the specific conditions driving these costs helps explain the pricing and might inform your decision about whether to get insurance in the first place.
Brachycephalic Respiratory Issues
Flat-faced breeds (French Bulldogs, English Bulldogs, Pugs, Boston Terriers) are six times more likely to file claims for breathing-related conditions. BOAS surgery ranges from $1,500 to $5,000+, and many of these dogs need multiple procedures over their lifetime.
Corneal ulcerations (those bulging eyes are vulnerable) add another $1,000+ per incident. And brachycephalic dogs are far more likely to require emergency intervention for overheating. If you live somewhere hot, factor that into your calculations. I think comprehensive coverage is non-negotiable for any brachy breed.
Hip and Elbow Dysplasia in Giant Breeds
Large and giant breeds are genetically predisposed to malformed joints. Treatment options range from $1,500 for conservative management to $5,000+ for total hip replacement — per hip. Breeds most affected include Mastiffs, Bernese Mountain Dogs, Newfoundlands, Rottweilers, German Shepherds, and Labrador Retrievers.
Bloat (Gastric Dilatation-Volvulus)
A friend’s Great Dane bloated on a Sunday night. $6,200 and a 2am emergency surgery later, the dog survived. Barely. Deep-chested breeds like Great Danes, German Shepherds, Dobermans, and all the mastiff types are susceptible to GDV, where the stomach fills with gas and rotates. Without emergency surgery (typically $3,000-$7,500), it’s fatal. And it comes on fast; owners have hours, not days. Preventive gastropexy during spay/neuter is worth discussing with your vet — it runs about $400-$1,200 and can save your dog’s life.
Heart Conditions and Cancer
These two deserve to be talked about together because they’re the long-game costs that catch people off guard.
Dobermans are notorious for dilated cardiomyopathy. Cavalier King Charles Spaniels have astronomical rates of mitral valve disease. Standard Schnauzers deal with pulmonic stenosis. Cardiac workups alone run $500-$1,500, and ongoing medication for heart failure adds $100-$300 monthly. That’s $1,200-$3,600 per year just in maintenance meds.
On the cancer side, Golden Retrievers, Bernese Mountain Dogs, Rottweilers, Boxers, and German Shepherds all have elevated rates. Treatment can easily exceed $10,000-$15,000 for chemotherapy or surgery. For these breeds, comprehensive coverage isn’t a luxury. It’s the whole point of having insurance.
Von Willebrand Disease
A bleeding disorder that affects Dobermans, Scottish Terriers, and several other breeds. Any surgery becomes more complicated and expensive when your dog doesn’t clot properly. Two sentences, but it matters.
10 Most Affordable Dog Breeds to Insure
Good news if you’re budget-conscious: plenty of wonderful dogs won’t break the bank to insure.
| Breed | Average Monthly Cost | Why They’re Cheaper |
|---|---|---|
| Chihuahua | $33-44 | Tiny size means lower vet costs across the board. Medications, anesthesia, surgery — everything is cheaper when the patient weighs 6 pounds. |
| Yorkshire Terrier | $37-52 | Small, generally healthy, and they live forever. A 15-year-old Yorkie is basically middle-aged. |
| Miniature Poodle | $40-55 | One of the healthiest purebreds out there. Fewer hereditary issues than most breeds their size. |
| Australian Shepherd | $41-59 | Active and robust with good genetic diversity. They do get MDR1 gene issues, but overall claim rates stay low. |
| Dachshund | $38-55 | Cheap to insure despite the back problems (IVDD). Their small size keeps treatment costs manageable even when things go wrong. |
