Before acquiring our puppy (who is now 8 years old), I researched all the available pet insurance companies. Eventually, I narrowed the list to three possibilities. Our neighbor to the left took one company; neighbor to the right took a different one; and my husband and I chose Trupanion. Over the years we are the ONLY ones happy with our choice. Our puppy was seriously ill the first six months of his life and Trupanion was supportive, never once questioning a claim. Later, when we wanted a second opinion for surgery, they were great. No "gate" to go through to get an approval; they just said "Of course you should have a second opinion" and they paid that bill in full. That's the kind of service one doesn't forget.
