I was quite happy over the years with Trupanion. Had a few small claims; nothing big. Until last month. Over the course of 2 hours, my dog became paralyzed in his back legs, due to a completely ruptured disc. Immediate spine surgery was needed, which was successful. So what do they do? Raise my monthly premiums by 37%. Shame on them. I also had to submit my claim 3 times, because "they never received it".
