Pet insurance for senior dogs
By Raúl Vaquerizo · Published · Editorial policy
You can usually still insure an older dog, but it costs much more and anything already in its vet record will be excluded. In the quote data we use, the median dog breed costs about $36 a month at age 3 and $129 a month in the senior band (ages 8 to 13), about 3.6 times as much. For a healthy senior with no major diagnoses yet, accident and illness insurance can still be worth it; for a dog with existing chronic conditions it often is not.
When is a dog a senior?
There is no single age. The American Animal Hospital Association (AAHA) defines a senior dog as one in the last 25% of its estimated lifespan. That makes breed size important:
| Dog | AKC life expectancy | Senior from about |
|---|---|---|
| Chihuahua | 14–16 years | 11 |
| Yorkshire Terrier | 11–15 years | 9.75 |
| Labrador Retriever | 11–13 years | 9 |
| German Shepherd | 12–14 years | 9.75 |
| Great Dane | 7–10 years | 6.4 |
| Bernese Mountain Dog | 7–10 years | 6.4 |
Giant breeds age fastest. In UK veterinary records, the median age at death of giant-breed dogs was 8.94 years, compared with 13.56 years for Yorkshire Terriers.
What senior dog insurance costs
Typical monthly premiums for an accident and illness policy ($500 deductible, 80% reimbursement, $5,000 limit), national average:
| Dog | Age 3 | Age 8 | Age 10 |
|---|---|---|---|
| Median breed | $36 | $79 | $117 |
| Chihuahua | $23 | $50 | $74 |
| Labrador Retriever | $42 | $86 | $120 |
| Golden Retriever | $41 | $87 | $125 |
| French Bulldog | $61 | $140 | $217 |
| Rottweiler | $63 | $136 | $196 |
MoneyGeek also reports an average of $206 a month for 15-year-old dogs. Use the calculator for your dog’s breed, age and state.
Why it costs more
Older dogs claim more and for more expensive problems. NAPHIA’s list of the largest claims paid in 2025 includes several older dogs: a 10-year-old small mixed breed ($60,100, liver disease), a 13-year-old medium mixed breed ($46,700, kidney disease) and a 13-year-old Jack Russell ($43,600, heart valve disease). Insurers price that risk in.
The pre-existing problem
The bigger issue for seniors is not price but exclusions. By the time a dog is a senior, its record often includes arthritis, dental disease, a heart murmur or lumps. Under the NAIC Pet Insurance Model Act, anything a vet advised on, treated, or that showed signs before coverage started counts as pre-existing and can be excluded. If your senior dog already has its main health problems diagnosed, a new policy will not cover them.
When senior coverage still makes sense
- Your dog is healthy, with a clean record. New illnesses, such as a cancer diagnosed after coverage starts, would be covered.
- You could not pay a large emergency bill. Accidents and sudden illnesses do not stop at eight.
- You keep an existing policy. If your dog has been insured since it was young, keep it: a condition the policy already covers cannot become pre-existing on renewal under the model act.
Ways to make it affordable
- Raise the deductible to lower the premium, if you can pay more upfront on a claim.
- Consider accident-only cover if illness is already largely excluded; NAPHIA’s average accident-only premium was $190 a year for dogs in 2025.
- Check enrollment age limits and senior-specific rules before you apply.
- Compare the annual limit with likely bills. A $5,000 limit can run out quickly on cancer care or major surgery.
