I gotta say, that's a helluva neat little trick, using our dogs' natural gluttony against them. Intrigued, I tried it out on my notoriously pill-averse old dog. She's not currently taking any meds, so I used a bit of diced onion (which she doesn't like) as a pill proxy. Worked like a charm. She was so intent on getting that second piece of cheese that she didn't hesitate for a second swallowing the first onion-loaded piece, even though after nine years she's pretty wise to the old balled-up cheese slice trick.
