Pet insurance comes in three flavors, and the price gaps between them are bigger than most people expect. An accident-only plan can run under $15 a month, while a full accident-and-illness plan with a wellness add-on can push past $75. Choosing between them is mostly a question of what you want the policy to do: cover disasters, cover sickness, or pay toward routine care too.
What accident-only pet insurance costs
Accident-only plans cover injuries, poisoning, and other sudden accidental events. They do not cover illness, hereditary conditions, or routine care. Because the risk pool is narrower, they are the cheapest option by far. Industry trackers put the 2026 average at about $16 a month for dogs and $9 for cats, with typical quotes running $10 to $20 a month.
Accident-only makes sense in two situations. First, as a budget safety net: it protects against the $2,000 to $5,000 emergency surgery that would otherwise land all at once. Second, for pets that cannot get illness coverage anyway. Senior pets and animals with pre-existing conditions are often declined for illness coverage or offered it at prices that are not worth it; an accident-only plan gives them something real at a modest price.
The catch is structural. Most expensive vet bills are not accidents. Cancer treatment, diabetes management, urinary blockages in cats, and cruciate ligament tears that develop over time are illnesses under most policy language. If your fear is a chronic diagnosis rather than a broken leg, accident-only will not help. See what pet insurance does not cover for the full exclusion picture.
What accident-and-illness plans cost
The standard comprehensive plan covers both accidents and illnesses: infections, cancer, allergies, hereditary and congenital conditions, and usually dental illness. This is the plan the averages describe. Expect roughly $40 to $65 a month for dogs and $22 to $35 a month for cats, varying with age, breed, and location. Young, healthy pets sit at the low end; older pets sit well above it.
This is the default recommendation for most owners because it covers the scenarios that actually bankrupt budgets. The gap between accident-only and accident-and-illness pricing is real, usually $25 to $45 a month for a dog, but it buys coverage for the category where the biggest bills live.

What wellness add-ons cost, and what they actually pay
Wellness plans are not insurance in the usual sense. They reimburse routine and preventive care: annual exams, vaccinations, flea and tick prevention, dental cleanings, and sometimes spay or neuter. Most are sold as add-ons to an accident-and-illness policy, though some insurers sell them standalone.
Industry pricing puts wellness add-ons around $20 to $30 a month, with annual benefit caps typically between $350 and $650. Do the arithmetic before adding one: if you pay $25 a month ($300 a year) for a plan that reimburses up to $450, your maximum net benefit is $150, and only if you actually spend the full $450 on covered routine care. Many owners spend less than the cap and would have been better off paying the vet directly.
Wellness add-ons make sense when you know your spending. A puppy’s first year stacks vaccinations, microchipping, and a spay or neuter into a predictable bundle, and a wellness plan can come out ahead there. For a healthy adult cat with an annual exam and basic vaccines, it rarely does. Run your actual last year of vet receipts against the plan’s benefit schedule before deciding.
Putting the three side by side
For a typical dog: accident-only runs about $16 a month, accident-and-illness about $43 to $62, and accident-and-illness plus wellness around $75 to $80. For a typical cat: about $9, $22 to $32, and $50 to $60 respectively. The jump from accident-only to full coverage is the important one; the wellness add-on is a budgeting tool, not protection.
If the budget is tight, accident-only plus a small emergency fund beats no coverage at all. If you can afford the full plan, that is where the value is, because illness is where the expensive surprises are. And if you are considering wellness, treat it as a discount program for care you were going to buy anyway, not as insurance. The framework for that decision is in our guide to how pet insurance works.
