I have used Advantage, Advantix, and Frontline Plus. I am sticking with the Frontline plus now. I have never had fleas with any of them, but Cooper did get a tick with either Advantage or Advantix (yuk!!) I buy it online in the 6 month supply...it's worth every penny to never ever see a flea! (or tick)
