Health gets complicated. That means calculating your dog's insurance quote can get complicated, too. Broadly, we calculate your insurance quote by looking at your dog's:
Age - Older dogs (despite what they may tell you) are a little more frail than their younger counterparts. This makes them more likely to get ill or have a pre-existing condition, which can impact your price.
Breed - Some breeds are more prone to certain health conditions than others.
Location - Where you (and your dog) live can impact price.
Lots of other factors go into this as well, but the majority of insurers will use the above as a baseline. But remember: the cheapest pet insurance out there may not have the cover you or your dog needs, so make sure you're getting something that works first.
