Frontline does not work here...you are SOOO right! I'm gonna have to check into the pill you are using. I've seen it at the vets. I've always had good luck with butter or cheese, but usually in a "play/reward-cookie" session. I just slip in the pill in whatever I have. Hot Dogs sliced thick enough to cover the pill work too. Just cut a little slit in it and poke the pill inside.
