Briggs will stop and sit at the door when we come in too! It's the best one I think!!! Like Goldenmom said it's all repetition. Keep the lead on when you come in the door and tell them to sit. Praise - do this everytime and soon it becomes habit. Now I don't even need to have the lead on and she will stop on the mat. I also make her sit and wait whenever I open any door. It's cute
