  • The only one I trust
    Have used Advantage II on all my animals for decades..One season I tried a different flea tx with added protection & my one dog got extremely ill..We almost lost her!! I switched back after she recovered & none of my animals have ever had a negative reaction to Advantage II & I have never had an issue with fleas..I shouldn't have messed with something that was working..Lesson learned by on 04/06/2020
  • Dogs do well in the winter.
    This product protects from giving fleas a warm place in the winter and ticks a place to jump to. by on 11/28/2019
  • awesome product
    We deal with fleas on our side of the mountains and ticks on the other, since using Advantage for 12 plus years we have NEVER had a flea or a tick! by on 10/21/2019
  • Always satisfied
    I must have protection from Ticks because we live in a forest and there are deer. I rely on Advantage II and have not been disappointed. by on 09/10/2018
  • Advantix II Keeps the terrible Tennessee Fleas Ticks GONE
    Tick and Flea's in the state of Tennessee are terrible Only stuff found to really work Plus I do admit I do dust under bedding etc with Diatomacious Earth I am horribly allergic to flea bites so do everything possible. Prefer Natural but none work as well. by on 08/06/2018
