Crush 'em. If it's a solid pill, grind it up under a flat-base mug (what I do, lol), then sprinkle it over his food. If it's kibble, add water and swirl it all around. If it's canned food, mix the powder in with the food. If it's a capsule, open it up and do the same thing (sprinkle it on food).
That's what I've done for years, and my dog's happy with the arrangement.
