My yellow lab has osteosarcoma, this is her second battle with it and she is only 4 years old. I took out insurance on her when she was just a few months old, I thought what the heck, and it was after I had to take one of our other dogs to the emergency vet clinic and it cost me $1275.00. I had no idea before that these things existed for our fur babies. I am so glad I purchased it, because without it, we would have had to let Abby go a long time ago. They paid every single claim with zero problems and some claims were in the thousands. They cover her prescriptions and her veterinarians recommended supplements for cancer which I actually get off of Amazon (usually 40 to 60% cheaper than getting them from the vet) to save both myself and Petplan some money. They pay for chemo as well. I will be a lifetime customer of this wonderful company. We have three large dogs and Petplan gives me piece of mind for when the unexpected happens and believe me, it happens.
