Yes, I have Trupanion for both; i think i'm fortunate b/c i enrolled both of them as soon as I brought them home so I had no pre-existing conditions to document.
I have Trupanion as well, have had for two months. I pay $90 a month for both Bullies. Do you mind saying if your cost is about the same? My mother has insurance for her Boxer and pays less than $20 a month. I don't know who it is through or what it covers though.
