My Tawny will eat anything that has peanut butter on it, she also thinks her heartworm medicine is a treat, she always looks for more. My old lab Bert used to roll everything is his mouth and if he found something foreign he would spit so hard it would bounce off the floor. He had to smell and taste everything before he would swallow. Every one of my babies were different, but Tawny has to be the easiest to get meds into. The say cheese whiz is good too.
