There is a product out called "Pill Pocket" where you insert the pill into the hollowed out treat, seal it and then feed it to your pet. You can get them in different sizes depending upon the size of the medication. "Pill Pocket" can be purchased online and in pet stores. I used to cut up hot dogs and cut a slit in it to hide the pill and that worked fine but my dogs have never been picky about food.
Good Luck!
