Accident-only vs accident and illness pet insurance
By Raúl Vaquerizo · Published · Editorial policy
An accident-only plan costs roughly a quarter of a full accident and illness policy. That’s the whole appeal. The catch is right there in the name: it pays when your pet gets hurt, not when it gets sick, and sickness is where most of the money goes once a dog or cat is past its first couple of years.
What each plan covers
NAPHIA, the trade association that tracks the US pet insurance market, describes the two products this way:
- Accident only: swallowed objects, cuts, car accidents, ligament tears, poisoning and similar injuries.
- Accident and illness: all of that, plus illnesses such as cancer, infections and digestive problems.
It’s worth looking at what people actually claim for. NAPHIA’s 2025 list of the most common conditions is led by digestive (GI) problems for both dogs and cats. For dogs, ear infections and skin conditions come next; for cats, dental disease and urinary tract infections. Not one of those is an accident.
What each plan costs
| Average annual premium, 2025 (NAPHIA) | Dogs | Cats |
|---|---|---|
| Accident only | $190 | $112 |
| Accident and illness | $836 | $435 |
For dogs, the average accident-only policy cost about 23% of the average full policy. For cats it was about 26%. Quote data points the same way: MoneyGeek’s averages are $19 vs $61 a month for dogs and $11 vs $32 for cats.
The gap grew in 2025. Accident and illness premiums rose 11.5% for dogs and 12.6% for cats, while accident-only prices barely moved (down 1.6% for dogs, up 1.4% for cats).
Accidents aren’t cheap either
Don’t read “accident-only” as “only small stuff”. A torn cruciate ligament in the knee, one of the injuries NAPHIA lists under accident-only benefits, typically costs $5,459 to $12,738 to repair. Whether your policy treats a particular tear as an accident depends on its wording, so check that if your dog is one of the breeds prone to cruciate tears.
Some of the biggest claims NAPHIA members paid in 2025 were injuries, too: $59,700 for a 4-year-old Toy Poodle mix with bite wounds, $43,400 for a 10-year-old Greyhound’s wound, and $37,400 for a 4-year-old cat’s trauma.
When accident-only is a reasonable choice
- Money is tight and you have some savings. You’re covered for the sudden, expensive injury, and you accept that illness bills come out of your own pocket.
- Your pet’s health problems are already excluded. If an older pet’s main conditions are pre-existing, a full policy wouldn’t cover them anyway. Accidents are still new events.
- You want something in place right now. It’s better than no cover while you compare full policies.
When it’s the wrong choice
- Your breed has a well-documented illness risk. Heart disease in Cavalier King Charles Spaniels, cancer in Golden Retrievers and kidney disease in Persians are all illnesses. An accident-only plan pays nothing for them.
- You’re buying it to cover “emergencies”. Plenty of emergencies are illnesses. Bloat, for example, is not on NAPHIA’s list of typical accident-only benefits.
A quick way to decide
Look at the actual difference in your case. For a median-breed 3-year-old dog, our estimate is about $36 a month for accident and illness and about $11 for accident-only, a difference of roughly $300 a year.
Then ask yourself one question: if your dog needed $3,000 of treatment for an illness next year, could you pay it without borrowing? If yes, accident-only plus a savings account is a defensible plan. If not, that $300 a year is buying you something real.
