This is one of the most important things to understand before buying pet insurance: pre-existing conditions are almost never covered. Here’s exactly what that means and how to protect your pet anyway.

The Short Answer
No. Pet insurance does not cover pre-existing conditions. If your pet showed symptoms of a condition — or was diagnosed with it — before your policy started (or during the waiting period), treatment for that condition won’t be reimbursed.
What Counts as “Pre-Existing”?
A pre-existing condition is any injury or illness that your pet had signs of before coverage began. It doesn’t have to be formally diagnosed — if your vet records show symptoms, the insurer can classify it as pre-existing.
| Example | Covered? |
|---|---|
| Allergy diagnosed before the policy | No |
| Limp noted at a vet visit last year | No (likely pre-existing) |
| New injury after coverage starts | Yes |
| Illness with no prior symptoms | Yes |
Curable vs. Incurable Conditions
Some insurers split conditions into two types:
Incurable (chronic) conditions
Things like diabetes, allergies, or heart disease. If they’re pre-existing, they’re excluded permanently.
Curable conditions
Things like a respiratory infection or a urinary tract infection. Many insurers will cover them again if your pet stays symptom-free for a set period (often 6–12 months).
How to Protect Your Pet Anyway
- Enroll early — the single best move. A healthy puppy or kitten has no pre-existing conditions.
- Don’t wait for symptoms — once a problem appears, it’s too late to insure it.
- Keep clean vet records — and review them for anything an insurer might flag.
- Ask about curable-condition coverage if your pet has had a minor, resolved issue.

Frequently Asked Questions
Can I get any coverage for a pet with pre-existing conditions?
Yes — you can still insure the pet for new, unrelated conditions. The pre-existing condition itself won’t be covered, but a future unrelated illness or accident would be.
How do insurers know about pre-existing conditions?
They review your pet’s veterinary medical records, usually when you file your first claim. That’s why honesty at enrollment matters.
Is a breed-prone condition considered pre-existing?
Only if your pet already showed signs of it. A breed being at risk for a condition isn’t the same as having it — if symptoms appear after coverage starts, it’s typically covered.
