Best Pet Insurance for Older Dogs: Age Limits, Costs and Catches

You can get pet insurance for most older dogs

Most insurers will still sell you a policy for an older dog, but each one draws its own line. Some stop taking new pets at a set birthday. Others take any age but shrink the coverage for the oldest dogs.

When does a dog count as “older”? The AVMA says dogs become seniors in the last 25 percent of their breed’s expected life span. That works out to roughly age 6 to 7 for giant breeds and 8 to 11 for small ones. So a 7-year-old Great Dane and a 10-year-old Chihuahua may face similar questions.

Age matters for two reasons. It decides whether you can enroll at all. And the older your dog is, the more of its health history is already on file, which shrinks what a new policy will pay for.

What are the enrollment age limits?

Enrollment age limits range from “before the 14th birthday” to “no limit at all.” Here is what insurers say on their own pages or in major reviews.

Insurer	Upper age limit for new dogs	Catch
Trupanion	Must enroll before the 14th birthday	Coverage continues for life once enrolled
Embrace	No upper age limit	Dogs 15 and older can only get accident-only cover
Pets Best	No age limits	Premiums rise with age
ASPCA	No upper age limit for dogs (per NerdWallet)	Confirm pricing on a quote

Some companies have a limit but don’t publish it. Lemonade’s own FAQ says a dog that has hit its age limit “may be declined entirely,” without naming the age. If your dog is 10 or older, confirm eligibility before you spend time on a long application.

One rule holds everywhere: once your dog is enrolled, most insurers let you keep renewing. The cutoff applies to new customers, not to dogs already on a policy.

How much more does insurance cost for an older dog?

Expect to pay roughly double what a young dog costs, and more each year after that. NerdWallet gathered sample quotes from four insurers for the same dog at two ages. At age 2, the monthly price ran from $30 to $53. At age 8, it ran from $59 to $117.

Sample dog	Monthly price range (4 insurers)
2 years old	$30 to $53
8 years old	$59 to $117

Insurers charge more because older dogs see the vet more. Pets Best says it plainly: age won’t limit eligibility, but “it does influence plan premiums.”

For context, the North American Pet Health Insurance Association (NAPHIA) reports that the average accident-and-illness policy for dogs cost $836 a year in 2025, about $70 a month. That average covers dogs of all ages, so a senior dog will usually sit above it. Our dog insurance cost guide breaks down the other factors, like breed and ZIP code.

You can pull the price down. A higher deductible (the amount you pay each year before the policy pays anything) lowers the premium. So does a lower reimbursement rate (the share of each covered bill the insurer pays back, often 70% to 90%). Our deductible guide shows how to pick one you could actually afford in a bad month.

Pre-existing conditions are the real limit for senior dogs

A pre-existing condition is any illness or injury your dog showed signs of, was diagnosed with, or was treated for before coverage began. Every major insurer excludes them. For an older dog, that list can be long.

Insurers split pre-existing conditions into two kinds:

• Curable conditions clear up fully, like an ear infection or a bout of vomiting. Some insurers will cover them again after a symptom-free stretch. Lemonade, for example, says that in most states it can cover temporary conditions that resolve with no symptoms or treatment for at least 12 months.
• Incurable conditions never count as cured. Arthritis, allergies, cancers and hormone diseases like diabetes fall here.

Insurers typically review your dog’s vet records when you file a claim. If a vet once wrote “mild stiffness in hips,” a later arthritis claim will likely be denied. Our pre-existing conditions guide explains how insurers review those records.

Watch for bilateral conditions too. These are problems that can affect both sides of the body, like cruciate ligament tears. If one knee was injured before you enrolled, many policies treat the other knee as pre-existing as well. Orthopedic problems also tend to carry longer waiting periods (the time after you buy before certain conditions are covered). Our waiting periods guide lists typical lengths.

Which senior dog problems can insurance help with?

Insurance helps most with the big new diagnoses that come with age. According to the AVMA, cancer causes almost half of deaths in dogs over 10. Heart disease, kidney disease, liver disease, diabetes and joint disease are also common in senior pets.

These problems get expensive because they need tests first. One insurer’s published cost guide puts a dog CT scan at $1,500 to $3,500, depending on where it’s done. An accident-and-illness policy would usually pay its share of that bill, minus your deductible, if the problem is new. Our cancer coverage guide goes deeper.

Dental disease is the other big one. The AVMA says most pets show early gum disease by age 3, so an old dog’s mouth is rarely spotless. PetMD reports $350 to $500 for a routine cleaning at a general vet and $500 to $2,500 per tooth for extractions. The example bill on this page uses figures inside those ranges. Dental coverage varies a lot between policies, so check our dental coverage guide before you count on it.

The AVMA also recommends that senior pets see a vet twice a year or more. Those checkups are routine care, so a standard policy won’t pay for them unless you add a wellness add-on (an extra that reimburses set amounts for preventive care).

Is accident-only insurance a good fallback for an old dog?

Accident-only insurance works as a fallback when illness cover is out of reach, but it leaves the biggest senior risks uncovered. An accident-only plan pays for injuries like broken bones, bite wounds, swallowed objects and car accidents. It does not pay for illnesses such as cancer or kidney disease.

It is cheap. NAPHIA’s 2025 figures put accident-only plans at $190 a year for dogs, about $16 a month. And it may be your only insurance option: Embrace, for example, offers dogs 15 and older accident-only cover.

	Accident-only	Accident and illness
Average 2025 dog premium (NAPHIA)	About $16/month	About $70/month
Broken leg, swallowed toy, bite wound	Covered	Covered
Cancer, diabetes, kidney disease	Not covered	Covered if new
Best for	Dogs too old for illness cover, tight budgets	Healthy seniors who still qualify

Not every company sells this kind of plan. Lemonade, for one, only offers accident-and-illness coverage. Our accident-only guide covers the tradeoffs in more detail.

What “best” means for an older dog

The best policy for an older dog is the one that will still accept your dog and pay for the problems it is likely to get next. No single company wins for every dog. Use these checks instead of a ranking.

Question to ask	Why it matters for a senior dog
Will you enroll my dog at its current age?	Cutoffs range from the 14th birthday to none at all.
Is illness covered, or only accidents?	Some insurers drop older dogs to accident-only.
How are pre-existing conditions judged?	A 12-month symptom-free rule can bring back curable issues.
How fast do premiums rise at renewal?	Senior prices climb every year.
Is there a per-condition or annual limit?	An annual limit caps what the policy pays each year; cancer care can hit a low cap quickly.
Is dental illness included?	Old dogs often need extractions.
Are exam fees covered?	The exam fee is the charge for the vet visit itself, and some plans exclude it.

If you are weighing cover for an older cat too, our senior cat insurance guide runs the same checks with feline conditions in mind. And if your dog is one of the breeds prone to cancer, such as a golden retriever, the annual limit deserves extra attention.

Is pet insurance worth it for older dogs?

Pet insurance is usually worth it for an older dog that is still fairly healthy and can get illness cover. It is rarely worth it for a dog whose main health problems are already on record.

It tends to pay off when:

• Your dog has few or no diagnosed conditions.
• One surprise bill in the thousands, like a $1,500 to $3,500 CT scan, would force a hard choice.
• You can afford a premium near double the young-dog price.

It makes less sense when:

• Arthritis, heart disease or other chronic problems are already in the records.
• Only accident-only cover is available and your dog rarely gets into trouble.
• You could set aside the premium each month and keep it untouched.

A middle path: price an accident-and-illness plan with a high deductible. You keep protection against a big new diagnosis while keeping the monthly cost lower. Our guide on whether pet insurance is worth it walks through the math.

Bottom line

You can insure most older dogs, but check the age cutoff first, because some insurers stop at the 14th birthday and others drop old dogs to accident-only. Premiums for an 8-year-old dog ran roughly double a 2-year-old’s in NerdWallet’s sample quotes. Anything already in your dog’s records will stay excluded, so the sooner you enroll, the more a policy can cover. The best plan is the one that still takes your dog, covers new illnesses and has a premium you can keep paying as it rises.
