I heard good things about K9Advantix, so I switched and that was a mistake.
I have a 90 pound Rottie that swims so I bought the K9Advantix since it is supposed to be water proof. Let me tell you, it DOES NOT work. After 10 days, I am getting approximately 5 to 15 ticks off her a day and she is an inside dog!!!! I have another older dog and I have gotten a few ticks off him as well and he does NOT swim.
