Can I get pet insurance if my dog already has a medical condition?

Absolutely. I tell owners this all the time—just because your dog has a bad knee doesn't mean they can't get covered for a sudden cancer diagnosis or swallowing a rock. The pre-existing issue will be excluded, but everything new and unrelated is covered after the waiting period.

What is the difference between curable and incurable pre-existing conditions?

Curable conditions are temporary problems that go away with treatment, like an ear infection or a UTI. If your dog stays symptom-free for a set time (usually 6 to 12 months), some insurers will cover them again. Incurable conditions are permanent, lifelong battles like diabetes or hip dysplasia, and almost all insurance companies will permanently refuse to cover them.

Does any pet insurance cover incurable pre-existing conditions?

Right now, AKC Pet Insurance is the only big name doing this. But you have to pay into the policy for a full 365 days before they'll start covering the incurable condition. It's a long wait, but if your dog is young, it can be worth it.

Dog Insurance for Pre-Existing Conditions: What You Need to Know

I’ve worked in emergency vet hospitals for 15 years, and the hardest conversations I’ve ever had start with the phrase, “Is this covered?” Too often, an owner brings in a dog they love—a dog who already has a limp, a chronic cough, or itchy skin that won’t quit. They want to get insurance now, but they’ve heard the rumors: if your dog is already sick or hurt, insurance companies will just laugh you out of the room.

Let me be direct. Getting insurance when your dog already has medical baggage is frustrating. The industry standard is to deny coverage for anything that happened before your policy started. But here is the secret they don’t always advertise: having a pre-existing condition doesn’t mean your dog is uninsurable. You just have to know how the system works.

What Exactly is a Pre-Existing Condition?

In the veterinary world, a pre-existing condition is any symptom or illness we document in your dog’s chart before your insurance waiting period is up. It doesn’t even have to be a firm diagnosis. If you tell me your Golden Retriever was limping on Tuesday, your insurance kicks in on Wednesday, and the doctor diagnoses a torn ACL on Friday… that limp is in the chart. The insurance company will see it and label the ACL tear as pre-existing.

Insurance companies typically review your dog’s medical records from the past 12 to 24 months during the underwriting process to find these conditions.

Curable vs. Incurable Conditions

When an insurance underwriter looks at your dog’s medical history, they split pre-existing conditions into two buckets: curable and incurable. Knowing the difference can save you thousands.

The Heartbreak: Incurable Conditions

These are the lifelong battles. Diabetes, cancer, heart disease, hip dysplasia, and environmental allergies. Once your dog has one of these, almost every insurance company will permanently refuse to cover it.

If your dog is diabetic, you’ll be paying out-of-pocket for insulin and those tiny glucose test strips. But here is the silver lining: if that same diabetic dog swallows a squeaker toy and needs an emergency $3,000 bowel obstruction surgery—a surgery I assist with weekly—your insurance will cover it. The obstruction has nothing to do with the diabetes.

The Loophole: Curable Conditions

Curable conditions are temporary. Think ear infections that make them shake their head all night, urinary tract infections, kennel cough, or a broken toe that heals perfectly.

Many good insurance companies will reinstate coverage for these issues if your dog goes through a “symptom-free” period. Usually, if your dog goes 180 to 365 days without needing treatment or showing symptoms for that specific issue, the slate is wiped clean.

How Top Pet Insurance Companies Handle Pre-Existing Conditions

I review medical records for insurance claims every day. Here is my blunt assessment of how the big players handle past medical histories:

Pets Best

They are surprisingly forgiving for curable conditions. If your dog is fully healed and symptom-free from something like a UTI for just 180 days, they’ll cover it if it happens again. (Note: They still exclude knee and ligament issues).

Embrace

They dig deep into the last 12 months of your dog’s records. If your dog had an ear infection but has been clear for 365 days, Embrace covers it.

Lemonade

They pay out claims fast, but they are brutal on pre-existing conditions. If your dog had an issue before you signed up, Lemonade will likely deny coverage for that issue for the rest of the policy’s life. No resets.

Trupanion

They don’t do symptom-free resets, but they offer a per-condition deductible. If your dog develops a new chronic issue like allergies after you enroll, you only pay the deductible once for that illness, forever, rather than resetting every year.

Nationwide

They permanently exclude incurable issues, but offer a 6-month (180-day) symptom-free reset for minor, temporary problems.

AKC Pet Insurance

They are the only major provider offering coverage for incurable pre-existing conditions. The catch? You have to keep the policy active for 365 straight days before that coverage kicks in.

Provider Comparison Breakdown

Insurance Provider	Covers Curable Conditions?	Symptom-Free Requirement	Covers Incurable Conditions?
Pets Best	Yes	180 Days	No
Nationwide	Yes	180 Days	No
Embrace	Yes	365 Days	No
Lemonade	No	N/A	No
Trupanion	No	N/A	No
AKC Pet Insurance	Yes	365 Days	Yes (After 365-day wait)

The Bilateral Condition Trap

Please, listen to me on this one. You need to understand “bilateral exclusions.” A bilateral condition can happen on both sides of the body—like a torn ACL or hip dysplasia.

If your dog blows out their left knee before your insurance starts, the company won’t just exclude the left knee. They will almost always permanently exclude the right knee, too. In the vet field, we know that if one knee goes, the other is working overtime and will likely tear eventually. A TPLO surgery to fix a torn ACL runs between $4,000 and $7,000. It is a massive expense, so check your policy documents for bilateral exclusions.

Managing Uncovered Conditions

If your dog has an incurable pre-existing condition, you need to budget for their specific care. Here’s what you’re realistically looking at out-of-pocket:

Canine Diabetes: $100 - $300 a month for insulin, syringes, prescription food, and routine blood curves.
Environmental Allergies: $80 - $200 a month. Usually, this means Cytopoint injections or Apoquel pills to stop the miserable itching, plus medicated baths.
Osteoarthritis: $50 - $150 a month for pain meds like Rimadyl, joint supplements, and Librela injections just so they can comfortably stand up.

Even with these bills, you still need insurance. A dog with allergies can still get hit by a car. I’ve seen owners forced to choose economic euthanasia because they were already paying $150 a month for allergy meds and couldn’t afford a sudden $5,000 emergency bill.

Actionable Recommendation

Don’t wait. Follow these steps:

Ask for a Medical Record Review: Before your cancellation window closes, make the insurer review your vet records. Get it in writing what they consider pre-existing so you aren’t blindsided at the emergency clinic.
Pick Based on the Problem: Minor past issues? Go with Pets Best or Nationwide for the short reset period.
Think Long-Term for Chronic Issues: If your dog has a lifelong illness and is still young, look at AKC Pet Insurance. Pay out-of-pocket for a year to get that pre-existing coverage unlocked.

Every day you delay is another day your dog could develop a new symptom that will be permanently excluded. Secure a policy to protect against the unknown, and budget separately for the conditions you already know about.
