We have PetPlan USA insurance for Milo. It does not cover routine stuff but does cover accidents, illness, and hereditary diseases. We have not had to use it, but I feel better knowing that it is there just in case. Here is a link to their website:
Pet Insurance Dog Policies from Petplan USA
I used this website to help me research the many different pet insurance policies out there:
Pet Insurance Review - comparison of VPI, ASPCA, etc.
Good luck!
