I rescued a much older dog three months ago. When I picked him up from the rescue, he had no known health issues or pre-existing conditions other than bad joints. That said, within one week of having him, we were at the ER and then vet for a tick borne illness that has taken us months to treat. He also has a weak stomach lining but to get to the bottom of both of those issues, we had numerous vet visits and costs associated with it.
Trupanion was offered to me the day I rescued my dog and to be honest, I wasn't sure what to expect of it. I am so grateful they approached me from day one and that I had it when I did. It has saved me a lot financially but a lot more importantly, has put me at ease about finding him the best care.
lastly, their customer service is excellent. They always pick up the phone, answer my questions quickly and confidently and they respond back to your claims within one week.
