I recently put in our first claim with Trupanion. My gsd was diagnosed with pancreatitis, it came on extremely fast and was scary! The customer service at Trupanion is great and when I asked how I go about making a claim the woman i spoke to was so helpful that I asked about some other issues we had with our staffy. She was adopted 3years ago and recently had a pellet surface in her face, we had the pellet removed and never thought about putting in a claim because we thought that would be considered pre-existing. The woman I spoke to told me to file the claim because we didn't have previous knowledge of the injury. Our claim was initially lost, once I called it was cleared up rather quickly and both claims were paid out. My only complaint is that our rates went up a couple days later.
