Does pet insurance cover Addison's disease in dogs?

Addison's disease is a lifelong hormone problem. Insurance can help if the first signs show up after the sickness wait. If your dog already had on-and-off tummy trouble in the notes, expect it to be left out.

What Addison's disease is

Your dog has two small glands near the kidneys. They make hormones that help the body handle stress and keep salt and water in balance. With Addison's, those glands stop making enough.

Vets call it "the great imitator." The signs come and go and look like lots of other things. Here is what to watch for:

  • Being tired or low on energy.
  • Throwing up or loose poop that comes and goes.
  • Not wanting to eat, or slowly losing weight.
  • Drinking and peeing more.
  • Shaking or weak muscles.

Sudden collapse, a very slow heartbeat, or being hard to wake is an emergency. Go to an emergency vet right away.

The good news: Lemonade says most dogs do very well with the right care. It just never goes away. Dogs take medicine for life.

The short answer

  • First signs after the sickness wait ends:
    • Addison's is a sickness, not an accident. On an accident-and-illness plan, tests, medicine, and checkups can be covered.
    • Lemonade says Addison's is covered on its base plan as long as it is not pre-existing. That includes tests, medicine, and the ongoing bloodwork.
    • Embrace says the same: covered if it shows up after the policy starts and the wait is over.
    • Your deductible, payback %, and yearly cap still apply. Verify on the quote form.
  • Signs before signup, or during the wait:
    • Treated as already there before coverage.
    • Addison's never goes away. Do not count on a "cured" rule bringing it back later.
    • It does not need a diagnosis. A note like "vomiting, on and off" can be enough to cause trouble.
  • Accident-only: Will not pay for Addison's. It is a sickness, not an injury. See accident-only vs wellness.

Old tummy trouble in vet notes

This is the tricky part. Addison's is often found late, because the early signs look like a sensitive stomach or a dog who is just getting older.

Lemonade says that once signs show up, the condition is typically considered pre-existing. So a few off weeks before you sign up can matter later.

Insurers read the vet records. Here is how far back some of them look:

  • Embrace: asks for the last 12 months of records.
  • Trupanion: looks back 18 months for signs.
  • Fetch: asks for the last 12 months of records.
  • Lemonade: asks for about the last 12.5 months.

If any of these show up before the wait ends, expect Addison's bills to be at risk:

  • Throwing up or loose poop that came and went, with no clear cause.
  • Weight loss or a poor appetite in the notes.
  • A blood test that showed odd salt levels.
  • A visit where the vet said your dog was weak, shaky, or dehydrated.
  • A stomach-medicine or fluids visit for a dog that then bounced back.

Most of those visits turn out to be nothing. But if Addison's shows up later, a claims reviewer may look back and ask whether the early signs were the same problem.

Not sure what is in the record? Ask your vet for a copy before you shop. Embrace also offers a free Medical History Review after you buy, but you have to ask for it.

If your dog already has the diagnosis, assume it is carved out. Then decide if a policy still makes sense for other accidents and illnesses. See problems already in the record and senior dogs over 8.

Which dogs get it

Lemonade says it is rare, and most often hits young to middle-aged female dogs. So it is not only an old-dog problem. But it can be missed for a long time, and older dogs have more vet records to look through.

Breeds Lemonade names as more likely:

  • Portuguese Water Dogs
  • Standard Poodles
  • Nova Scotia Duck Tolling Retrievers
  • Bearded Collies
  • Great Danes
  • West Highland White Terriers

Lemonade also lists it for Goldendoodles, from the Poodle side.

Other hormone problems in dogs have their own pages. See Cushing's, low thyroid, and diabetes.

Anything can go stale. Verify on the quote form and the issued policy.

  • Lemonade:
    • Has a page on Addison's (updated June 2026). It says Addison's is covered on the base plan if it is not pre-existing.
    • Lists tests, medicine, and ongoing bloodwork. It says the Visit Fee add-on can help with the exam fee at each checkup.
    • Illness wait is 14 days. Signs in that window count as pre-existing.
  • Embrace:
    • Has a page on Addison's. It says tests, daily hormone medicine, and regular checkups can be covered if it starts after the policy and the wait.
    • Pre-existing means anything that showed signs before the policy or during the wait.
    • It says early signs can be vague and easy to miss, which makes the wait period matter more.
  • Fetch:
    • Fetch says pre-existing means anything noticed before signup or during its illness wait of up to 15 days.
    • Fetch says it can cover some curable pre-existing conditions. Addison's lasts for life, so do not count on that.
    • We did not find a Fetch page about Addison's by name. Verify on the quote form.
  • Pets Best:
    • Its sample policy says a condition is pre-existing if a vet gave advice, the pet got treatment, or there were signs before the start date or during the wait.
    • We did not find a Pets Best page about Addison's by name. Accident Only does not cover illness.
  • Spot:

  • Trupanion:
    • Trupanion looks back 18 months for signs before the start date.

Costs, from tests to monthly shots

Treatment usually means a shot about once a month plus a small daily pill. The shot is often called DOCP. Vet sources say the pills are often prednisone.

Your vet also needs blood tests to check salt levels and adjust the dose. Never stop or change the medicine on your own.

Ranges from a vet cost site (RealVetCost):

  • Tests to find it: $300 to $600.
  • Medicine for life: $50 to $100 a month.
  • A yearly total with checkups: $800 to $1,500.
  • One emergency crisis with hospital care: $1,000 to $5,000.

Lemonade's Goldendoodle page lists an average treatment cost of $800 to $2,000 for Addison's. Those are rough ranges, not your bill. Things to check on the quote form:

  • Is take-home medicine covered? That is most of the cost here.
  • Are exam fees covered, or is that an add-on? You will have many checkups.
  • Is the yearly cap high enough for a crisis plus a year of medicine?
  • Deductible and payback % still apply to every bill. A new year can reset them.

What wellness and accident-only will not do

Wellness packages help budget for shots and yearly checkups. They are not sickness coverage when your dog needs blood tests and lifelong medicine.

Accident-only pays for injuries, not hormone problems. See accident-only vs wellness. Related reading: kidney disease, enrollment age limits.
