Shane loves to great us when we come home, but he greets us before we have a chance to even pull in the driveway. Shane has this very bad habit of running straight up to the car, while it is still moving, and sit there. He won't move if you honk at him, he won't move if u try "squeeze by." He just sit there or run right along side of it. I am very scared because I am afraid one day he may accidentally get hit. How can I train him to wait until the car is done moving to approach?
