I have had great success in getting my Pit-mix to gulp ANY pill by smearing it with a generous dollop of liverwurst. No go with cream cheese, or peanut butter--- but she waits every night for her "treats", --vitamin, thyroxine, and glucosamine smeared with liverwurst. And if I am late--- she will whine to remind me! Thanks, will try Comfortis, nothing else is working.
