No treat, no bed!
My collie absolutely loves these. As soon as he has been out for his night time wee, he stands staring at the tin on the shelf until we give him one. On the odd occasion that we have forgotten, and gone upstairs, he has stayed downstairs in the same spot until we noticed and went back down to give him one. After he has had one, he heads straight up to his bed without being asked to. Cute!
