The years when a pet is most likely to need expensive care are the same years in which insurance becomes the hardest to buy. That is not a coincidence. It is how insurers price risk.
When a pet becomes "senior"
There is no single age. The American Animal Hospital Association defines a senior dog as one in the last 25% of its expected lifespan, which depends heavily on size and breed. It considers cats senior from about age 10. For senior pets, the association recommends a medical workup once or twice a year, including routine blood and urine tests (AAHA Senior Care Guidelines).
More visits and more tests mean higher routine costs. Older age also brings the chronic conditions that drive large claims.
The industry's latest report lists the largest claims it paid in 2025. Several went to older pets: $46,700 for kidney disease in a 13-year-old dog, $43,600 for heart disease in another 13-year-old dog, and $35,900 for kidney disease in a 12-year-old cat (NAPHIA).
What changes with age
- Premiums rise. Insurers commonly increase premiums as a pet ages. Under the NAIC model law, insurers must disclose whether they raise premiums or reduce coverage based on the pet's age or claim history ( NAIC Model Act #633 ).
- New policies may have age limits. Some insurers will not write a new policy for a pet above a certain age, or offer only accident coverage.
- Pre-existing conditions accumulate. An older pet has a longer medical record. Anything noted in it before a new policy starts may be excluded.
- Continuity becomes valuable. Under the model law, a condition your current policy has covered cannot be reclassified as pre-existing at renewal. Your insurer also cannot require a vet exam for you to renew. Switching insurers gives up both protections.
What the policy actually says
For an older pet, read these provisions before anything else:
- Age-based premium changes: how much, how often, and whether there is any cap.
- Coverage reductions: whether the reimbursement rate or annual limit falls at certain ages.
- Chronic condition coverage: whether ongoing conditions such as kidney disease or arthritis stay covered year after year, or are limited per condition.
- Renewal guarantee: whether the insurer can decline to renew your pet's policy.
The 4 questions to ask your insurer
- "How will my premium change at each birthday from here?"
- "Is there any age at which my coverage is reduced or ends?"
- "Are chronic conditions covered for the life of the policy, or capped?"
- "If I raise my deductible, how much does the premium fall?"
The fourth question is your main tool for keeping a senior pet's coverage affordable. A higher deductible keeps protection against large bills while lowering the cost of routine claims you may be able to pay yourself.
If your older pet is not insured yet
- Get quotes anyway. Some insurers accept older pets, often with exclusions for existing conditions.
- Consider accident-only coverage if comprehensive coverage is unavailable or unaffordable. It still protects against injuries.
- Build a dedicated savings fund for the conditions insurance will not cover.
Coverage check
The bottom line: for an older pet, the most valuable feature of a policy is often its continuity. Understand how age changes your premium, protect the coverage you already have, and use the deductible, not cancellation, to manage the cost.
