I first got a PetPlan policy in 2009. I was told that that the yearly premiums would increase 10% a year until my dog turned 12 years; at which time they would continue unchanged. This has not been the case at all. Last year they got a different underwriter and my premium increased roughly 20%. This year they increased it about 25% and I have cancelled my renewal. I would not have taken out a policy at all had I known that when my dog aged they would dramatically increase the premiums.
