It should be fine, Adrea. One of my dogs and several of our fosters have been vet-prescribed Drontal while they were on Advantage and/or Revolution without any ill-effects. I was told they don't interfere with each other. If in doubt, just ask your vet.
Btw, stick around and feel free to post in the introduction forum. Pictures of your pooch are most welcome
