I'm having a problem with my dog. Every single time she sees a cup with a drink in it, she takes her nose and tips it over. I think she does it because she wants ice. She absolutely loves ice. I have no idea how to make her stop doing it. She knows she's not supposed to do it so she only does it when she thinks no one is watching her. If she's about to tip it over and you look at her she backs up really quick and sits down. Does anyone have any idea what I can do to make her stop???
