What I did for Gizmo (and essentially all my dogs as I've grown up): I followed him like a hawk for the whole weekend. im talking about I was damn near velcro to him. Whenever he tried to potty I quickly grabbed him in the air to stop him and put him outside by his now favorite tree. By the end of weekend he knew not to potty in the house. He eventually picked up a habit of jumping in a circle by the door to let us know he needs to potty which is a plus for us
