I have a 3 year old Boxer that unfortunately has already started to develop mast cell tumors. We have had to have 2 removed and have 3 more coming up. Luckily we signed up for the most expensive VPI coverage that does cover cancer-related procedures. I am pleased with the amount that we receive back in coverage but with any insurance, I wish they covered more because vet bills can add up quickly. I recommend VPI to anyone I know who has a pet and I will continue to do so and continue to use VPI for my pets.
