Ok,,, do nt laugh,,, But Merlin has taken to pooping at the end of our side door walk and on the driveway,,, and its directly in the path of where everyone who comes to see us has to walk!

Is there any product I can spray on the concrete to deter him from doing this anymore,, or something I can do besides yelling NO at him.... I cant spend the time he is out watching him like a hawk....
