Key Takeaway: Pet insurance is worth it for most Spokane pet owners, but which plan is worth it depends entirely on whether you buy accident-only or full coverage. Accident-only runs roughly $10 to $25 a month and covers injuries: broken bones, swallowed objects, bite wounds. Full coverage adds illness protection, the thing that actually generates most claims, for three to four times the price. The right call depends on your pet's age, breed, and how much a surprise $4,000 bill would hurt.
Your neighbor's Lab swallowed a sock last spring. The insurance covered it, the bill disappeared, and now you're wondering if you should get a policy too.
Here's the question nobody answers clearly: accident-only or full coverage? They're not the same product at different prices. One covers the sock. The other covers the sock and the cancer diagnosis three years later. Picking wrong doesn't cost you a few extra dollars a month. It can mean writing a check for thousands out of pocket for something you assumed was handled.
Outline
What Accident-Only Pet Insurance Actually Covers
Accident-only pet insurance pays for sudden, unexpected injuries. Broken bones. Torn ligaments. Swallowed toys, socks, or rocks that need surgical removal. Bite wounds. Being hit by a car. If it happened in a single moment and wasn't caused by a disease process, it's probably covered here.
What it never covers is illness. Not cancer, not diabetes, not allergies, not infections, not arthritis. According to the Washington Office of the Insurance Commissioner, accident coverage typically runs alongside illness coverage as a bundled product. When you buy accident-only, you're specifically opting out of that illness half.
The appeal is the price. National averages for accident-only coverage sit around $190 a year for dogs and $112 for cats, according to NAPHIA's industry data. That's roughly $16 and $9 a month. For a young, healthy, indoor-leaning pet, that premium can look like free money sitting in an emergency fund.
What Full Coverage Adds (And Why It Costs Three Times More)
Full coverage, usually called "accident and illness," covers everything accident-only covers plus medical conditions: cancer treatment, chronic disease management, infections, digestive issues, skin conditions, and more. It's the difference between a safety net for bad luck and a safety net for biology.
The price reflects that. NAPHIA's most recent data puts average annual accident-and-illness premiums at $836 for dogs and $435 for cats nationally, compared to $190 and $112 for accident-only. That's roughly 4.4 times the price for dogs.
Why does illness coverage cost so much more? Volume. The National Association of Insurance Commissioners notes that most pet owners who buy insurance prefer comprehensive plans, and claims data backs up why: illness claims vastly outnumber accident claims over a pet's lifetime. Roughly one in four dogs will develop cancer at some point. Treatment can run $5,000 to $15,000 or more. Accident-only pays none of it.
The Real Cost Comparison: Accident-Only vs. Full Coverage
Here's where the math gets concrete. Say your dog swallows a sock. Depending on whether it's lodged in the stomach or has traveled into the intestine, surgery to remove it can run anywhere from $1,500 to $5,000, with complications pushing that figure higher. Both accident-only and full coverage pay for that.
Now say your dog develops a torn cranial cruciate ligament, which is common in larger breeds and often shows up with zero accident trigger, just wear and repeated stress. Surgery typically runs $2,800 to $6,400 depending on the technique and your dog's size. This is where things split. If your dog's ligament tore from jumping off the porch, some insurers may process it as accident-related. If it developed gradually, as CCL tears often do, an accident-only policy may deny the claim outright, because it's classified as a degenerative condition, not an injury.
That gray area is exactly why the Washington OIC tells consumers to compare policy limits and exclusions carefully before buying rather than assuming "accident" means every injury-adjacent event.
When Accident-Only Actually Makes Sense
Accident-only isn't a bad product. It's a mismatched product for some owners and the right fit for others.
It makes sense for a young, healthy dog or cat with a tight monthly budget, where the real fear is a catastrophic one-time bill rather than ongoing care. It fits an older pet who already has a illness-related preexisting condition that full coverage would exclude anyway, since you'd be paying the higher premium without gaining the illness protection you actually want. It also works as a bridge: some owners start with accident-only in the first year to establish coverage, then upgrade once their budget loosens.
The tradeoff you're accepting: zero protection against the single most expensive category of veterinary spending, chronic and serious illness. If that tradeoff doesn't bother you, accident-only is a reasonable, affordable choice.
When Full Coverage Is Worth the Extra Premium
Full coverage earns its higher price when the thing you're actually worried about is a long illness, not a single bad accident. Chronic conditions like diabetes or allergies can run hundreds of dollars a month indefinitely. A cancer diagnosis alone can wipe out years of accident-only premium savings in a single treatment plan.
The math tends to favor full coverage for most owners once you look past the sticker price. You might pay $20 to $40 more per month than accident-only. But a single serious illness diagnosis can generate claims worth thousands, something no accident-only policy will ever touch no matter how minor or major the diagnosis.
The Age and Breed Math That Changes Your Answer
Age matters more than almost any other factor. Buy full coverage while your pet is young and healthy, and illness conditions that show up later get covered because they weren't preexisting when you enrolled. Wait until your pet is seven or eight, and any condition already brewing gets excluded, which defeats much of the purpose of upgrading.
Breed matters too. Large and giant breeds carry higher orthopedic and cancer risk. Certain purebred cats and dogs carry documented hereditary condition risk that full coverage addresses and accident-only simply ignores by design.
What Washington Law Requires Your Insurer to Tell You
Washington passed Senate Bill 5319 in 2023, now codified in state law, specifically to stop pet insurers from burying this exact distinction in fine print. Under RCW 48.205, insurers selling pet policies in Washington must disclose upfront whether a policy excludes coverage based on preexisting conditions, hereditary disorders, congenital anomalies, or chronic conditions.
That matters directly for the accident-only versus full coverage decision. Under RCW 48.205.050, when an insurer denies a claim as a preexisting condition, the burden of proof falls on the insurer, not on you. The law also bans insurers from requiring a vet exam just to renew your policy, and it prohibits marketing wellness programs as if they were insurance.
In practice, this means any agent or insurer selling you a pet policy in Spokane has to spell out, in writing, exactly what your plan excludes. If they can't answer that question directly when you ask, that's a signal to keep shopping.
How to Decide: A Simple Framework
Run through these four questions before you buy either type of plan:
- How old is your pet right now? Under three years old, full coverage locks in illness protection before anything shows up on record. Over seven, weigh whether illness coverage would even apply to conditions your pet may already be developing.
- What's your pet's breed risk? Large breeds and certain purebreds carry documented orthopedic and hereditary risk that accident-only won't touch.
- Could you absorb a $5,000 illness bill without insurance? If the honest answer is no, full coverage is the one doing the actual job you need insurance to do.
- Is your real fear a single bad accident, or a slow-building health problem? Accident-only solves for the first. Only full coverage solves for the second.
In twenty-plus years quoting policies across this market, the mismatch I see most often isn't the healthy young Lab on accident-only. It's the owner who bought accident-only for a puppy, kept it for six years to save a few dollars a month, and then watched their now-senior dog develop a thyroid condition that's permanently excluded because there was never an illness rider in place to begin with. The premium they saved for six years didn't come close to covering what they ended up paying out of pocket.
Neither accident-only nor full coverage is automatically the right answer. It depends on your pet, your budget, and how much risk you're comfortable carrying yourself.

FAQ
Is pet insurance worth it for a healthy young dog?
Often yes, especially full coverage, because enrolling before any illness appears means future conditions won't be excluded as preexisting. Waiting until problems show up limits what any policy will cover.
What's the difference between accident-only and accident-and-illness pet insurance?
Accident-only covers sudden injuries like broken bones or swallowed objects. Accident-and-illness, or full coverage, adds protection for diseases, chronic conditions, and cancer, for roughly three to four times the premium.
Does accident-only pet insurance cover torn ligaments?
It depends on the cause. A ligament tear from an acute trauma, like a fall, may qualify as an accident. A gradual degenerative tear, common in larger dog breeds, is often classified as illness-related and excluded.
Can I switch from accident-only to full coverage later?
Usually yes, but any condition that developed while on accident-only may be treated as preexisting and excluded from the upgraded policy. Switching early, before problems appear, avoids that gap.
Does Washington law require pet insurers to disclose exclusions?
Yes. Under RCW 48.205, insurers selling pet policies in Washington must disclose exclusions for preexisting conditions, hereditary disorders, and chronic conditions before you buy.
How much does pet insurance cost in Washington?
Accident-only typically runs $10 to $25 a month. Full coverage typically runs $30 to $70 a month for dogs and somewhat less for cats, depending on age, breed, and the insurer.
Is accident-only pet insurance a waste of money?
Not necessarily. For a young, healthy pet with a tight budget, it provides real protection against catastrophic injury costs. It's only a poor fit if your actual concern is long-term illness risk.
What happens if my pet has a preexisting condition?
Most insurers exclude preexisting conditions regardless of plan type. Under Washington law, the insurer must prove the condition existed before coverage started, not the other way around.
