I did a lot of research on pet insurance plans and went with Healthy Paws about three years ago. They've been great to work with. Very prompt reimbursement and great customer service.
Just recently, After I submitted a claim for my dog, i realized i had never updated my address on the Healthy Paws website. I worried that my check was going to be delayed endlessly. However, once I alerted customer service to the problem they immediately offered to cancel the check and issue another one to my current address.
I love the piece of mind that having good pet insurance brings. I don't have to stress about $$ when my dog needs care.
