My experiences with Healthy Paws has been exceptionally good. I would agree with many of the positive posters that most of the negative comments seem to be from people that did not read or understand the terms of the policy.
Recently my boxer tore her CCL and required surgery to insert a metal plate and screws. Healthy Paws processed the claim quickly (the check arrived prior to the credit card bill) and even helped obtain her medical records from a different vet. Per the policy the vet examinations were not covered but I purchased the policy to cover the big ticket items, so 90% of the surgery and therapy visits are covered (after the deductible). I am very happy with the service I have received and I believe their explanations of the benefits have been spot on.
