We ranked every breed we’ve deeply researched by documented health severity, not marketing claims. A Bernese Mountain Dog’s risk profile looks nothing like a Chihuahua’s, and the gap is bigger than most owners realize.
Which Pet Breeds Need Insurance Most?
Every breed guide on this site cites real, sourced data, peer-reviewed studies, veterinary registries, breed-specific cohort research, rather than vague “prone to health issues” language.
That gives us something most comparison sites don’t have: a genuinely comparable dataset across 16 breeds, spanning both dogs and cats, built from consistent research standards rather than mixed sourcing quality.
This article settles which pet breeds need insurance most, not by cuteness or popularity, but by the actual severity of documented health risk, using our own independently verified data rather than marketing claims from any insurer.
How we built this ranking
Each breed on this list was scored using three factors we could independently verify in our own research: the severity of the primary documented risk (is it life-threatening or manageable), how well-established the risk is in veterinary literature (a single blog claim ranks lower than a peer-reviewed cohort study), and the realistic cost burden if the condition occurs.
We did not rank based on premium price alone, since a cheap policy that excludes your breed’s actual, documented risk isn’t a good value regardless of how attractive the monthly number looks.

Why cats rarely appear on lists like this one
Most “which pets need insurance most” content skews almost entirely toward dogs, not because cats are healthier, but because far less large-scale veterinary research exists on cat breeds specifically, a gap in the literature rather than a gap in actual feline risk.
Dog breed health studies, especially from institutions like the Royal Veterinary College and Swedish insurance registries, are simply more numerous and better funded, which skews what gets written about, not necessarily what actually matters most for a given pet’s health.
That research gap doesn’t mean feline risk is lower, it means it’s less documented. Ragdoll’s HCM and FIP profile, and Maine Coon’s specific genetic cardiac mutation, are backed by real peer-reviewed data that’s just as severe as several dog breeds ranked above them.
We included both breeds at their genuinely earned position in this ranking rather than defaulting to a dog-only list simply because more content exists elsewhere for dogs.
What this ranking does and doesn’t mean
A lower rank does not mean a breed is risk-free, and a higher rank does not mean every individual pet of that breed will develop the condition we cited. This ranking reflects documented population-level severity, the kind of statistical risk that makes insurance mathematically sensible, not a prediction about any specific dog or cat, and never a guarantee either way.
A Chihuahua at rank 16 can still develop an expensive, unexpected condition, just as a Bernese Mountain Dog at rank 1 can live a long, healthy life without ever developing cancer.
What this ranking is genuinely useful for is prioritization. If you’re choosing between two breeds, or trying to decide how seriously to take insurance for a breed you already own, this gives you an apples-to-apples comparison built from consistent research standards.
That’s something no single breed page, ours or a competitor’s, can offer on its own, since a single breed page has no basis for comparison against anything else.
A pattern worth noticing
The top of this ranking is dominated by cancer and severe cardiac risk, not the orthopedic conditions that generate the most claims industry-wide. Frequency and severity are different things.
A condition that happens often but is treatable, like patellar luxation, ranks lower here than a condition that happens less often but is frequently fatal, like Bernese Mountain Dog cancer.
Frequently asked questions
Bernese Mountain Dogs rank highest in our research on which pet breeds need insurance most, with a documented cancer mortality rate of 55 to 58% across two peer-reviewed studies, the most severe single statistic we found across all 16 breeds researched.
No. Every breed on this list, including the lowest-ranked, has documented health risks that can generate real veterinary costs. This ranking reflects relative severity based on our own research, not an absence of risk for lower-ranked breeds specifically.
Most such lists rank by average premium price, which reflects what insurers charge, not necessarily the underlying health severity. This ranking is built from the documented medical severity we found in our own independent research into each breed, regardless of what any provider currently charges to insure them.
Because the underlying research is more nuanced than a single label suggests. The large-scale study behind the “highest epilepsy risk” figure codes all seizure disorders as one category, without distinguishing genetic idiopathic epilepsy from structural causes like brain tumors.
A separate, breed-specific referral hospital study found the latter is far more common in Boxers specifically, which changes what the statistic actually represents.
Yes. As we research additional breeds in more depth, we’ll add them to this comparison using the same methodology, rather than estimating data we haven’t independently verified ourselves.
The bottom line: which pet breeds need insurance most
Severity, not frequency, is what should drive how seriously you take pet insurance for a given breed. The breeds at the top of this list carry risks that are not just common but genuinely life-threatening, cancer, sudden cardiac events, serious neurological disease, while breeds further down tend toward conditions that are manageable, even if expensive.
Wherever your pet falls on this list, the same rule applies across every guide on this site: enrollment timing, before any symptom of any kind appears, is what actually determines whether any of this research translates into real coverage.
