For Tango I have to do what Karen described. She's a slow eater whether it's a treat or a meal so she notices the pill right away and she probably thinks eating is a waste of time, she'd rather play with a ball than eat anyday. For the others, I usually just wrap it in some cheese or put it in their dinner. They all live for food and don't even notice. If the Peanut Butter thing works for you then I'd continue to do it.
