Help!! Bonzer has got a horrible habit of pooping right at the bottom of our stairs!! He only did this as the snow started and we have made a HUGE shoveled area for him to go. He just goes immediately as he gets to the bottom of the stairs. SOmeone told me there is a spray that you can put where you don't want them to go, anyone have any clues? It was not so bad until I fell going down the stairs and landed in it. The snow is melting today and I have such a mess!! Please help!!
