Accident-only is the tier insurers put on the menu so the entry price looks reachable. It is a real product with a real use, and it is also the easiest way to end up with a policy that denies the claim you eventually file. This page prices the gap, lists what the cheap tier never pays for, and names the owners it actually fits. Our own quoted prices for either tier are pending first quote run, so the figures below belong to the publishers named beside them.
How much cheaper is accident-only coverage?
Accident-only runs at less than a quarter of the full-coverage average: $190 a year for dogs and $112 for cats, per NAPHIA's 2026 State of the Industry report covering 2025. Full accident and illness coverage averaged $836 for dogs and $435 for cats in the same report. The dog gap is about $646 a year, or roughly $54 a month.
The direction of travel matters more than the snapshot. NAPHIA's average accident-only dog premium was $204.16 a year in 2023 and $190 in 2025, while the accident and illness average for dogs climbed from $675.61 to $836 over the same period. The cheap tier got slightly cheaper while full coverage rose about 24 percent. That divergence is the market pricing illness risk upward, and it is worth understanding before you read the discount as a bargain.

What does accident-only never pay for?
Accident-only pays for injuries and nothing else, which means it excludes every condition on NAPHIA's 2025 top-five claim lists for both species. For dogs those are gastrointestinal issues, ear infections, skin conditions, anxiety and behavioral issues, and allergies. For cats: gastrointestinal issues, dental disease, urinary tract infections, anxiety and behavioral issues, and respiratory issues. Ten entries across two species, and not one of them is an accident.
The costs behind those exclusions are the reason this matters. Nationwide's claims analysis puts skin allergies for dogs at $265 over 30 days and $841 over a full year, measured at the 80th percentile of billed cost. Feline diabetes reaches $2,240 a year on the same basis. As of 2026, CareCredit's national averages put cancer therapy at $5,254 for dogs and $4,269 for cats, with a full chemotherapy course at $3,000 to $10,000 or more. Billed costs vary widely by region and clinic. An accident-only policy contributes zero dollars to any of those bills.
What does accident-only actually cover?
Injuries only, and injury bills still run well into four figures: swallowed objects, broken bones, lacerations, bite wounds, and accident-related emergencies. Money, citing MetLife Pet Insurance, puts a whole emergency visit at $150 to $5,000 for dogs and $150 to $3,000 for cats, with wound treatment at $800 to $2,500. Lemonade's January 2025 claims data puts endoscopic foreign body retrieval at about $1,058 and open abdominal surgery at about $1,314 for the procedure alone, with a full intestinal blockage episode running roughly $1,600 to $7,500. Pawlicy Advisor and Money give wider spans for the same episode, up to $10,000 for dogs. Again, billed costs vary widely by region and clinic.
One classification warning before you assume a torn knee ligament is an accident. Insurers differ on whether cruciate disease is written as an injury or as an orthopedic illness, and orthopedic waiting periods run as long as six months at some insurers, sometimes waivable with an exam. Confirm the classification in the policy document rather than the marketing page, and read how waiting periods work first.
Who should actually buy accident-only?
Four situations fit this tier, and the strongest by far is a pet whose illnesses are already excluded as pre-existing. They are listed here in descending order of fit.
- A pet whose illnesses are already excluded. If a chronic condition pre-dates coverage, the illness half of a full policy is buying you less than the brochure implies. Accidents are unrelated to medical history by definition, so accident-only prices a chronically ill pet the same as a healthy one. The other paths open to a pet with a diagnosis are set out in pre-existing conditions.
- A budget where the real alternative is nothing. At $190 a year for a dog, the tier turns a $5,000 emergency into a deductible plus a coinsurance share. A thin policy beats no policy when the choice is binary.
- A young pet in a household that will upgrade later. Enrolling accident-only starts the relationship, but it does not protect you: illnesses that appear while you hold the cheap tier become pre-existing conditions for the upgrade. That risk is real and it is the reason we rank this third rather than first.
- An owner who wants catastrophe cover only. If your fear is a car, a fight, or a swallowed sock, and you would fund an illness yourself, the tier matches your actual worry.
If none of those describe you, buy the full tier. The commercial comparison lives at best accident-only pet insurance, and the cheapest full-coverage options are ranked in cheapest pet insurance.
Which insurers sell an accident-only tier?
Availability is uneven, and the tier menu decides your shortlist before price does. ASPCA Pet Health Insurance sells an accident-only tier alongside its full plan, verified in our ASPCA review. Fetch sells no accident-only tier at all, so its entry point is a full accident and illness policy, confirmed in our Fetch review. Spot and Pets Best both advertise an accident-only tier, and our verification of their current tier menus is pending, so treat the quote flow as binding until we publish the check.
Here is the limitation we cannot solve for you. NAPHIA publishes average premiums by tier but does not publish how many policies sit in each tier, and the NAIC collects that split without publishing national values. So nobody, including us, can tell you what share of owners choose accident-only or how they fare. We can tell you what each tier costs and what each one excludes, and that is where our evidence stops.
Which tier should you buy?
Buy accident and illness coverage unless one of the four cases above describes you, because the claim data says pets get sick far more than they get hurt. Accident-only wins in one clear case: a pet whose illnesses are already excluded, where you are paying for the half of the policy that still works. If the appeal of the cheap tier is purely the price, compare it against funding the difference yourself first, using the ten-year scenarios in pet insurance versus a savings account.
