Why Pet Insurance Premiums Can Jump Sharply at Renewal, and Why Switching Isn't Simple

Pet owners are increasingly reporting a jarring pattern with pet insurance: an affordable first-year premium followed by a steep price increase at renewal. Some pet owners have described increases of several hundred percent when their policy came up for renewal, according to a recent report examining the issue.

Industry professionals cited in the report point to several reasons behind this pattern. Some insurers set introductory prices low to attract new customers, without that first-year premium reflecting the true cost of covering the pet over time. As pets age, file claims, or as veterinary costs rise more broadly, renewal premiums can catch up. Veterinary care inflation has been outpacing general consumer prices for years, driven partly by more advanced diagnostics and treatments becoming standard, which insurers say gets passed along in renewal pricing.

Data cited in the report also shows that average premiums have climbed industry-wide. Dog insurance premiums rose noticeably between 2020 and 2024, with much of that increase concentrated in the most recent year, while cat premiums increased at a slower pace over the same period. Older pets can also cost substantially more to insure than younger ones, since insurers often treat age similarly to how auto insurers weigh a driver's age as a risk factor. Not every insurer handles aging the same way, however, and some base pricing more on the pet's age at enrollment rather than continually raising rates simply because the animal gets older.

This creates a real complication for anyone comparing providers. If a renewal premium spikes, switching insurers isn't as straightforward as it might be with auto or home insurance, because most pet insurers exclude pre-existing conditions. A pet that has since developed a chronic or recurring health issue may not receive coverage for that condition under a new policy, leaving owners to weigh a higher renewal cost against the risk of losing coverage for an existing condition.

For someone shopping for a policy, the practical takeaway is to look past the first-year quote. It's worth asking each insurer directly how it calculates renewal pricing, whether age, individual claims, or broader group claims experience affect future premiums, and whether new-customer pricing differs meaningfully from what existing policyholders pay later. Enrolling a pet while it's young and healthy can also reduce the number of conditions later excluded as pre-existing. Before switching providers, it helps to confirm exactly how a prospective insurer treats any condition already in the pet's medical history, and to consider whether adjusting the deductible or reimbursement level with the current insurer might resolve a premium increase without the risks that come with switching. Comparing how different companies approach these renewal and aging policies, such as Trupanion, can be one part of a broader research process before committing to a plan.
