Does pet insurance cover heart disease?

All 8 insurers we compare cover hereditary and congenital conditions, as long as it is not pre-existing: if your dog showed signs before the policy started, or during the waiting period, it will be excluded. The practical rule is to enroll before any symptoms appear.

Heart disease usually needs care for the rest of the dog's life, so the cost repeats every year. Look at how the deductible works: most insurers apply it once a year, while Trupanion uses a deductible per condition, paid once for the dog's life for that condition. Some plans also cap how much they pay for a single condition, so read the limits section.
