I can offer two suggestions --
1) Coat the pill with butter or margerine then wrap it in a small piece of lunchmeat -- roast beef works well 'cause it's got a lot of smell -- give one plain snippet of lunchmeat, the pill lunchmeat packet, and follow with a lunchmeat chaser.....
2) If the sick sorry rascal spits it out then..... recoat the pill with butter, open the little darlin's mouth, put the pill WAY back on his tounge and then give it a little shove, hold his mouth shut and rub his throat until he swallows.
#2 REALLY TRULY works, but personally, I only use that as a last resort (It also works with cats and horses
).
