Mawahhahaha - Wanna keep your dog busy? Take a spoonful of peanut butter - type and ingredients your choice. I use the fresh ground stuff with nothing but peanuts - and stick it to the roof of his mouth. It is so funny to watch them get it unstuck. A great healthy treat (if you want to be nice you can put it inside a kong) Try a RAW soup bone with the marrow inside. They are inexpensive and you can generally find smaller ones - when the get the marrow out you can stick peanut butter in them too. Here, they come about 6 to a package. I just freeze them and take them out when it suits my need.
