I have this problem as well. Both of mine are able to find the TINIEST pill! One choice is to grinde it up and put it in a little wet food. This is what I do to get my Japanese Chin/Poodle mix to take his Benadryl....but don't even get me started on this....he eats all kinds of stuff off of the floor but then won't eat a grape flavored pill!!!!!

Another great way is to use these little things that are made just for this problem. I think they are called Pill Pockets and they come in a green bag. They are essentially treats that are shaped kind of like a tiny little cup. You put the pill in there and pinch the top part closed and they never even notice. I definitely recommend these things! Good luck!
