What Does Pet Insurance Cover? (And What It Never Will)
Every pet insurance policy in the US is built on one of three chassis: accident-only, accident-and-illness, or accident-and-illness with a wellness rider. What you are actually buying varies enormously between them, and the marketing pages rarely make the gaps obvious. Here is the honest map, with every carrier claim below checked against the eleven insurers we track.
The three plan types
Accident-only covers injuries: broken bones, lacerations, bite wounds, swallowed foreign objects, toxin ingestion. NAPHIA’s 2026 report puts it at $190 a year for dogs — about $16 a month — and it excludes every illness: no cancer, no ear infections, no allergies. It makes sense as a budget floor for an older pet that no longer qualifies for full coverage, and rarely otherwise.
Accident-and-illness is the standard product, and the one the national averages describe. It averages $836 a year for dogs, about $70 a month, and covers accidents plus the full illness spectrum: cancer, infections, digestive disease, allergies, diabetes, and — with caveats — hereditary and congenital conditions.
Wellness coverage either bolts onto a base plan as a rider or is embedded in the policy itself. NAPHIA’s embedded-wellness figure for dogs is $1,414 a year, about $118 a month, and that 69% jump over accident-and-illness is the tell: it is a different product design, not a small add-on. A separate rider is not insurance in any meaningful sense — it is a pre-paid maintenance plan priced off a benefit schedule, and many return close to what they cost. Read the schedule before adding one.
| Plan type | Dogs / year | Dogs / month |
|---|---|---|
| Accident only | $190 | $16 |
| Accident & illness | $836 | $70 |
| With embedded wellness | $1,414 | $118 |

What accident-and-illness plans cover
The covered list is long and genuinely useful:
| Covered | Typical notes |
|---|---|
| Emergency care and hospitalization | Including overnight stays and ICU |
| Surgery | Torn ligaments, foreign-body removal, tumor resection, fracture repair |
| Cancer | Diagnostics, surgery, chemotherapy, radiation |
| Hereditary and congenital conditions | Hip dysplasia, IVDD, heart defects, patellar luxation — if not pre-existing |
| Chronic conditions | Diabetes, allergies, arthritis, epilepsy — covered for life once established post-enrollment |
| Diagnostics | X-rays, ultrasound, MRI, CT, bloodwork, biopsies |
| Prescription medications | For covered conditions |
| Specialist referrals | Oncologists, cardiologists, neurologists, orthopedic surgeons |
| Behavioral therapy | Included at Spot and Fetch; ASPCA covers it in its Complete Coverage tier; Lemonade sells it as an add-on; Pets Best limits it to its top tier |
| Alternative therapies | Acupuncture, hydrotherapy, rehab — availability varies by carrier, so confirm it in the sample policy |
Two coverage details separate good policies from mediocre ones. Exam fees — the charge for the vet visit itself, separate from the treatment — are excluded by some carriers and included at Fetch, Spot, ASPCA, Embrace, and MetLife. Lemonade sells exam-fee coverage as an add-on, Figo through its Powerups add-ons, and Pets Best only on its higher tiers. Healthy Paws and Trupanion do not cover them at all. Dental illness (periodontal disease, tooth resorption) is excluded by many plans but covered by Fetch for every tooth; dental injuries are covered almost everywhere.
What pet insurance never covers
The exclusion list is nearly identical across carriers, and this is where claims disputes live:
- Pre-existing conditions. Anything showing symptoms or diagnosed before enrollment or during the waiting period. Some curable conditions regain coverage after a symptom-free window — the full rules are in our pre-existing conditions guide.
- Routine and preventive care on base plans: vaccines, annual exams, flea and heartworm prevention, spay and neuter.
- Breeding, pregnancy, and whelping. Excluded nearly everywhere; a few carriers sell breeder riders.
- Cosmetic and elective procedures. Tail docking, ear cropping, declawing, dewclaw removal.
- Grooming, boarding, and training.
- Food and supplements, including prescription diets at most carriers — Embrace is a notable exception and covers prescription diets.
- Bilateral conditions with pre-existing history on one side. If your dog tore the left cruciate ligament before enrollment, most carriers treat a future right-side tear as pre-existing. This clause matters enormously for Labrador Retrievers and other cruciate-prone breeds.
- Experimental treatments not accepted as standard veterinary practice.
Hereditary conditions: the fine print that matters most for purebreds
Hereditary and congenital conditions are not a separate product line — they sit inside the illness category, so an accident-and-illness plan is what covers them. The catch is timing and carrier-specific carve-outs:
- Healthy Paws excludes hip dysplasia entirely for dogs enrolled after age six, and imposes a 12-month waiting period on it otherwise.
- Extended orthopedic waiting periods apply at most carriers even though the conditions are covered: Lemonade and Pets Best at six months on cruciate ligaments, Fetch, Embrace and Figo at six months on hip, knee or orthopedic conditions (each waivable with a vet exam), Nationwide at twelve months on cruciate ligaments, and MetLife at six months with no exam waiver.
- Nationwide’s lower-tier Major Medical plan pays on a benefit schedule with per-condition caps; the Whole Pet tier replaces that with percentage reimbursement.
Per-carrier waiting periods are tabulated in the waiting periods guide. If you own a breed with known hereditary risk — a French Bulldog for airway and spinal disease, a Golden Retriever for cancer — hereditary coverage is not optional. Verify it explicitly in the sample policy, not the marketing page.
What claims actually look like
Two NAPHIA datasets from the 2025 claims year are worth reading before you decide what “coverage” means in practice.
The most common conditions dogs are claimed for are ordinary, not dramatic: gastrointestinal problems, ear infections, skin conditions, anxiety and behavioural issues, allergies, growths and masses, eye disorders, diarrhoea, urinary tract infections, and musculoskeletal disease. That is what an illness plan pays for week to week — and it is why an accident-only plan leaves so much on the table.
The tail is why cover exists at all. The five largest single dog claims settled in 2025:
| Breed | Condition | Claim paid |
|---|---|---|
| Bernese Mountain Dog | Undiagnosed chronic illness | $66.6K |
| Small mixed breed | Undiagnosed hepatopathy | $60.1K |
| Toy Poodle mix | Bite wounds | $59.7K |
| Medium mixed breed | Acute renal failure | $56.7K |
| Old English Sheepdog | Anemia | $54.7K |
Source: NAPHIA 2026 State of the Industry Report, Section 6.
A $66.6K claim is roughly 80 years of average accident-and-illness premiums. Four of those five dogs are ordinary-sized, including a toy Poodle mix and a small mixed breed — catastrophic bills are not reserved for giant breeds. The breed pages carry the documented condition list behind that risk; see the Bernese Mountain Dog profile for hereditary cancer as a worked example.
How to verify coverage before you buy
Marketing pages summarize; the sample policy PDF is the contract. Before enrolling, download it from the carrier’s site and check four things: the hereditary-conditions clause, the exam-fee line item, the dental illness exclusion, and the bilateral-conditions language. Coverage terms also vary by state — the same carrier sells materially different policies in California and Texas. Finally, use the free-look period: check your policy documents for the cancellation window your state allows, during which you can cancel for a full refund if the issued policy does not match what you thought you bought.
How reimbursement actually works
US pet insurance is indemnity-style: you pay the vet, submit the claim, and get reimbursed a percentage (usually 70 to 90 percent) of covered costs after your deductible. The exceptions: Trupanion’s VetDirect Pay and Pets Best’s optional direct payment can settle with participating vets at checkout, which matters on a five-figure bill. Lemonade processes a large share of claims in minutes through its app.

FAQ
Does pet insurance cover surgery?
Yes. Surgery for covered accidents and illnesses — including anesthesia, hospitalization, and post-op care — is a core benefit of every accident-and-illness plan we track. Elective and cosmetic procedures are excluded.
Does pet insurance cover dental?
Dental injuries from accidents are covered by most plans. Dental illness such as periodontal disease is covered by only a minority — Fetch covers every tooth, illness included, while many rivals exclude it or require an annual cleaning first. Routine cleanings fall under wellness add-ons.
Does pet insurance cover vaccines and checkups?
Not in base plans. Vaccines, annual exams, flea prevention, and spay or neuter are routine care, covered only through optional wellness riders or embedded-wellness plans. Rider pricing is set by each carrier's benefit schedule, so ask for the schedule and add up the procedures you would actually use before deciding.
Does pet insurance cover hereditary conditions?
Hereditary and congenital conditions sit inside the illness category, so an accident-and-illness plan is what pays for them — but only if symptoms first appear after enrollment and any waiting period ends. Several carriers impose extended orthopedic waiting periods of six to twelve months, and Healthy Paws covers no hip dysplasia at all for dogs enrolled after age six.
Does pet insurance cover cancer treatment?
Yes. Cancer diagnostics, surgery, chemotherapy, and radiation are covered by accident-and-illness plans once the condition is not pre-existing. It matters: NAPHIA's 2025 claims data lists the largest single dog claim of the year at $66.6K, and hereditary cancer is the leading cause of the short lifespan in breeds such as the Bernese Mountain Dog.
What is never covered by pet insurance?
Pre-existing conditions, routine and preventive care on base plans, breeding and pregnancy, cosmetic procedures such as tail docking and ear cropping, grooming, boarding and training, most prescription diets, and the uninjured side of a bilateral condition where the other side was already damaged before enrollment.
