Pet Insurance

By Tahir Abbas, Editor · Last updated 28 October 2026

Pet insurance is one of those purchases you hope you will never need and are grateful for when you do. A single emergency vet bill in the United States can run into thousands of dollars, and most owners pay it out of pocket because they have no other option. A policy does not make vet care free, and it does not suit every pet or every budget. What it does is turn an unpredictable, potentially unaffordable bill into a predictable monthly cost, so that a decision about your pet’s treatment is never purely a decision about money.

This guide explains how pet insurance actually works in the US, what the different types of plan do and do not cover, what it costs on average, and how to choose between them. It is written to help you decide, including the situations where insurance is probably not worth it and saving the money yourself is the smarter move.

What Is Pet Insurance and How Does It Work?

Pet insurance is a contract between you and an insurer. You pay a monthly or annual premium, and in return the insurer pays back a share of your vet bills when your pet has an accident or becomes ill, subject to the terms of the policy. It is closer to property insurance than to human health insurance: there is no network of approved providers to stay inside, no co-pay card at the counter, and in most cases no pre-approval before treatment.

Almost all US pet insurance works on a reimbursement model. You take your pet to any licensed vet, pay the bill yourself, then submit a claim with the invoice and medical records. The insurer reviews the claim and pays you back the covered amount, usually by bank transfer. One notable exception is Trupanion, which can pay participating vets directly at checkout, so you only owe your share. A few other insurers offer similar arrangements with some clinics, but reimbursement after the fact is still the norm, which means you need to be able to cover a large bill up front while the claim is processed.

Three settings on your policy decide how much you get back:

Deductible. The amount you pay out of pocket before the insurer starts reimbursing. Most insurers let you choose, typically somewhere between $100 and $1,000. Many policies use an annual deductible, which you meet once per policy year. Some, such as Trupanion, use a per-condition deductible, which you pay once for each separate condition over your pet’s lifetime.
Reimbursement rate. The percentage of the covered bill the insurer pays after the deductible, commonly 70%, 80% or 90%. A few plans offer 100%, usually at a much higher premium. You pay the remaining percentage yourself.
Annual limit. The maximum the insurer will pay in a policy year. Limits commonly range from $5,000 up to unlimited cover. A low limit keeps the premium down but can run out exactly when you need the policy most, during a year with surgery or a serious diagnosis.

As a rule, a higher deductible and a lower reimbursement rate mean a cheaper premium but more cost left with you at claim time. The cheapest quote is rarely the best value if it leaves you exposed to the bills the policy was meant to protect against.

Types of Pet Insurance Plans

Accident-Only Plans

Accident-only cover is the simplest and cheapest type of policy. It pays for injuries from accidents: broken bones, swallowed objects, bite wounds, cuts, poisoning and similar emergencies. It does not pay for illness at all, so cancer, infections, allergies, diabetes and hereditary disease are all excluded. Accident-only plans suit owners who mainly want a safety net against sudden trauma and are comfortable self-funding illness, but they leave the most common and most expensive category of vet care uncovered.

Accident and Illness Plans

This is the standard comprehensive policy and the type most owners buy. It covers accidents plus illnesses: infections, digestive problems, cancer, allergies, skin conditions, and, on most plans, hereditary and congenital conditions such as hip dysplasia in dogs or heart defects, provided symptoms first appear after you enrol and after any waiting period. Chronic conditions that develop while the policy is active are generally covered for as long as you keep renewing, which is one of the strongest arguments for insuring a pet young and staying with the same policy.

Wellness and Preventive Care Add-Ons

Wellness cover is usually sold as an add-on to an accident and illness plan rather than as standalone insurance. It reimburses fixed amounts toward routine care: annual check-ups, vaccinations, flea and worm prevention, dental cleaning and sometimes spaying or neutering. Treat wellness cover as a budgeting tool, not insurance against risk. Add up the scheduled payouts before buying: if the add-on costs roughly what it pays out, you may be better off putting the same money aside yourself. Some owners still value it because it spreads a predictable cost across the year.

What Pet Insurance Covers

Exact cover varies by insurer and plan, but a typical accident and illness policy includes:

Emergency care and hospitalisation after accidents
Surgery, including for hereditary conditions on most comprehensive plans
Diagnostics such as blood tests, X-rays, ultrasound, MRI and CT scans
Treatment for illnesses including cancer, infections, allergies and digestive disorders
Prescription medication related to a covered condition
Dental illness and dental injury on many plans, though routine dental cleaning is normally a wellness item
Behavioural therapy, physical rehabilitation and alternative therapies such as acupuncture on some plans or as add-ons
End-of-life care, including euthanasia when medically necessary, on many policies

Cover applies at any licensed vet in the US on most policies, including emergency hospitals and specialists, and many insurers also cover treatment while travelling in Canada. There is no network to check before you go, which is a genuine advantage over human health insurance.

What Pet Insurance Usually Does Not Cover

The exclusions matter as much as the inclusions, and this is where buyers are most often disappointed:

Pre-existing conditions. Anything your pet showed signs of, was diagnosed with, or was treated for before the policy started or during a waiting period is excluded. This is the single most important concept in pet insurance. Some insurers will cover curable pre-existing conditions, such as a one-off ear infection or a stomach upset, once your pet has been symptom-free and treatment-free for a set period, often 12 months. Incurable conditions, such as diabetes or chronic kidney disease, are never covered if they pre-date the policy.
Waiting periods. Cover does not start the day you buy. Most policies have a short accident waiting period (often two or three days, sometimes none), around 14 days for illnesses, and longer special waiting periods, sometimes six months, for cruciate ligament and other orthopaedic problems. Anything that occurs during a waiting period becomes pre-existing.
Bilateral conditions. Many policies treat the two sides of the body as one condition. If your dog had a cruciate ligament injury in the left knee before the policy started, a cruciate injury in the right knee may be excluded as a bilateral condition, even though it is a different leg.
Exam fees. Some plans pay for treatment but not the consultation or exam fee that produced the diagnosis. Others include exam fees or offer them as an add-on. On a year with several vet visits, this difference adds up.
Routine and elective care. Vaccinations, check-ups, grooming, spaying or neutering and cosmetic procedures are not covered by accident and illness plans. Breeding costs and pregnancy are also excluded on most policies.

Read the sample policy, not just the marketing page, before you buy. The exclusions section is where the real product is described.

How Much Does Pet Insurance Cost?

The most reliable price benchmarks come from the North American Pet Health Insurance Association (NAPHIA), which publishes industry figures each year. According to NAPHIA’s 2026 State of the Industry report, covering 2025 data, the average annual premiums in the US were:

Accident and illness: $836 a year for dogs (about $70 a month) and $435 a year for cats (about $36 a month)
Accident only: $190 a year for dogs and $112 a year for cats
Accident and illness with wellness: $1,414 a year for dogs and $859 a year for cats

These are averages across millions of policies, not quotes. Your own premium can be far higher or lower. The main factors are your pet’s species, breed, age and where you live, plus the deductible, reimbursement rate and annual limit you choose. Large dog breeds with known hereditary problems cost more. Premiums rise as pets age, sometimes steeply for senior animals, and most insurers increase prices at renewal. Before committing, it is worth using our pet insurance cost calculators to model how different deductible and limit settings change both the premium and what you would actually get back on a typical claim.

Price is only half the comparison. Two policies at the same monthly price can pay out very different amounts because of exam fee exclusions, bilateral condition clauses, per-condition versus annual deductibles, and whether hereditary conditions are included. Compare like for like, with the same settings, before deciding which quote is really cheaper.

Dogs vs Cats: How Cover Differs

The mechanics of dog and cat policies are the same, but the risks they insure are not, which is why cat cover costs roughly half the price of dog cover on the NAPHIA averages above.

Dogs generate bigger and more frequent claims. Large breeds are prone to hereditary and congenital conditions such as hip dysplasia, elbow dysplasia and cruciate ligament disease, all of which can mean surgery costing several thousand dollars. Dogs also swallow things they should not, get into fights, and are injured outdoors more often. When you compare dog policies, hereditary cover, orthopaedic waiting periods and the annual limit deserve the closest attention. Our dedicated dog insurance guide goes through breed-specific risks and plan choices in detail.

Cat claims skew toward illness rather than trauma, especially as cats age: kidney (renal) disease, hyperthyroidism, diabetes, urinary problems and dental disease are common. Indoor cats have lower accident risk, which prompts many owners to ask whether they need cover at all. The honest answer is that indoor life removes some risks but none of the expensive illnesses, and cats are typically insured for longer because they live longer. The complete guide to cat insurance covers these questions, and our comparison of the best pet insurance for cats works through the leading plans side by side.

How to Choose the Right Pet Insurance Plan

Work through these steps in order; they will narrow a long list of insurers to two or three sensible finalists.

Decide what you are insuring against. If a $5,000 emergency bill would be a crisis, you need an accident and illness policy with a high or unlimited annual limit. If you could absorb that bill but not a $15,000 year of cancer treatment, the limit matters more than the deductible.
Set the deductible and reimbursement rate you can genuinely live with. A $1,000 deductible is only a saving if you have $1,000 available when your pet is ill. Many owners find a mid-range deductible with 80% reimbursement the balanced option.
Check the enrolment age rules. Most insurers accept puppies and kittens from around 8 weeks old. Some set a maximum enrolment age for new policies, often between 10 and 14 years, while others, including ASPCA and Spot, have no upper age limit for enrolment. Older pets can usually be insured, but premiums are higher and everything already diagnosed is excluded.
Read the exclusions for your pet’s breed. Hereditary and congenital cover, bilateral condition clauses and orthopaedic waiting periods affect some breeds far more than others.
Ask about discounts honestly. A multi-pet discount, commonly around 5 to 10% for insuring more than one pet with the same company, is the most widely available saving. Some insurers also discount for annual payment or for military and employer schemes. Discounts should break a tie between two good policies, not rescue a poor one.
Compare the same settings across insurers. Well-known names in the US market include ASPCA, Spot, Pumpkin, Trupanion, Pets Best, Lemonade, Embrace, Healthy Paws, Nationwide and Figo. They differ in deductible style, exam fee treatment, waiting periods and add-ons, so identical settings rarely produce identical cover. Our pet insurance comparisons lay these differences out insurer by insurer.

How Claims Work

Claiming is straightforward on most policies. You pay the vet as normal, then submit the itemised invoice and your pet’s medical records through the insurer’s app or website. The insurer checks that the condition is covered, that any waiting period had passed, and applies your deductible and reimbursement rate. Most straightforward claims are decided within days to a couple of weeks, though first claims can take longer while the insurer reviews your pet’s full medical history to check for pre-existing conditions. Keep your vet records complete and accurate; gaps and inconsistencies are the most common cause of delayed or disputed claims.

Two practical points are worth knowing before you buy. First, because you pay up front under the reimbursement model, the policy does not remove the need for short-term access to money or credit, except where direct vet pay is available. Second, claim every eligible bill, however small once your deductible is met. Owners who only claim for major treatment often leave routine reimbursements unclaimed that they have already paid for through their premiums.

Is Pet Insurance Worth It?

It depends on your pet, your savings and your attitude to risk, and any guide that gives a universal yes should not be trusted. Insurance is most likely to be worth it if you enrol a young, healthy pet before any condition can be labelled pre-existing, if your breed carries known hereditary risks, and if a large unexpected bill would force you to choose between treatment and money. It is least likely to be worth it for an older pet with several existing conditions, since those conditions will be excluded and the premium will be high, or for owners with a solid emergency fund who are comfortable self-insuring and understand they are accepting the risk of a very large bill.

The middle option some owners choose is a cheaper accident-only policy plus a dedicated savings account for illness. That combination covers sudden trauma while building a fund, but the fund takes time to grow and an early serious illness can outrun it. There is no option with no risk; there is only choosing which risk you prefer. Our pet insurance guides explore these decisions topic by topic if you want to go deeper on any of them.

Frequently Asked Questions

Can I use my own vet with pet insurance?

Yes. US pet insurance does not use provider networks, so you can visit any licensed vet, including emergency clinics and specialists. Most policies also cover treatment in Canada, and some extend further for travel.

Does pet insurance cover pre-existing conditions?

No insurer covers incurable pre-existing conditions. Some cover curable ones, such as minor infections or injuries that have fully resolved, after a symptom-free period defined in the policy, commonly 12 months. Anything diagnosed before your policy starts or during a waiting period is otherwise excluded.

When is the best time to insure my pet?

As young as possible. Enrolling a puppy or kitten before any health problems appear keeps the exclusions list empty, avoids most waiting period complications, and locks in the lowest premiums. Every condition your pet develops before you insure becomes a permanent exclusion.

Will my premium go up?

Almost certainly, yes. Premiums typically rise at renewal as your pet ages and as vet costs increase. The size of increases varies a lot between insurers, and a history of claims can affect renewal pricing with some companies. Budget for the policy to cost more in your pet’s senior years than it does today.

Can I insure more than one pet?

Yes. Each pet gets its own policy, premium, deductible and limit, based on its own age, breed and health. Most insurers offer a multi-pet discount when you insure two or more pets with them, and a claim for one pet does not reduce the cover available for another.
