When Frontline became ineffective in my area, I switched to Advantix II. That being said, however, all dogs are different. Bailey used to get itchy in the spot where the Advantix was applied, but Tyler has never had a reaction to it. Frontline, on the other hand, didn't bother either of them. Guess it's just trial and error, although it can be a very costly trial with the price of these preventatives. Good luck.
