Potty Trained?

After several months I think our dog is trained!! He hasn't had an accident for quite some time but the problem has been getting him to let us know when he has to go out (pretty much we have been trained to watch the clock and take him out). Well the past week he has been going to the door and either whining or scratching at the door to go out!! We are hoping that he will do more of the whining since we aren't always in the room but we will take what we can get. I am so excited!!
