Please remember that Advantage does nothing to kill ticks. My experience this summer (worst that I have experienced in many years) is that I needed Advantix II and alternated with Frontline Plus.
My neighbor reported that she tried Fiprogard to save money and it did not work on her dogs at all.
I think that what works depends upon each dog's location and individual exposure opportunties.
