I use food too...I've used bread..cheese...meat. What I usually do (well I did this at first, but Nebo's not picky so he takes it no matter what now) is form 2 balls of the same stuff ahead of time. Like 2 little balls of bread, then one ball the same size with the pill in it. Give them the two "fakes" first then they don't notice with the third.

They make "playdough" for dogs thats edible....works great to hide pills in. I'm not sure if picky dogs would like it though. Neither Reggie or Smokey would eat the stuff.
