I'll second the treat idea. When I had to give Harley her Drontal, I gave it to her in Pill Pockets; I gave her two without a pill in them as a treat, and the third had the Drontal stuck inside it. She ate all of them, and it made the whole giving a pill situation a lot more pleasant than it otherwise would have been. I also made a big deal about her eating the one with the pill in it - she likes being told how good she is.
Well I have been randomly giving her treats when I pet her so she doesn't know that every time I approach her is pill time. It seems to be a bit better today (only 10 pills to go!)
