That was great Julie!
makka, I introduced the towel as a tug type of toy. He loves tug so there wasn't any need to get him hyped up over it. Now when he sees it he knows something special is going to happen, since the towel isn't left laying around for him to tear up. My trainer said one thing to remember is when you wash it, use plain water, as they can find it by the detergent smell when you hide it.
