I signed up with VPI when we first got my dog. This was my first experience with pet insurance and its been quite positive. Much easier than human health insurance! The plan I have is about $30 a month, but they pretty much pay for every visit, medication (including flea and tick meds, if needed) and since my dog, Jack, had a very unexpected surgery at 1 year old (he had an allergic reaction to his rabies shot and needed a resulting tumor removed) it was money well spent. We didn’t pay a dime. They’re really easy to deal with; you just print out a claim form and bring it with you to the vet, have the vet sign and then mail it in. You get reimbursed within a week or so, its very fast. There are a few other companies, but this one seems like the best, most established and least expensive.
