I've been with Trupanion for almost 4 years now, and when people ask how I like my pet insurance I only have great things to say. They are quite literally the reason my dog is still alive, as there is no way I would have been able to cover all his medical costs on my own. A couple small errors over the years that were rectified by my calling in, but they were just honest human error and were corrected quickly and easily. Note that my premiums HAVE gone up twice now in the time I have been with them, but it was a fairly small amount each time. They provided ample notice before the rate adjustments as well.
I have a 3.5years old boston terrier with ongoing allergy issues. The support Trupanion provides in covering 90% of the bills allows me to provide the proper care to my dog. The vet faxes off all the paperwork for me, and I usually get an email within 1-2 days from Trupanion saying my claim has been received, and then 2-3 days later an email saying a cheque was cut and is on its way to me. Very pleased with their service.
