another idea seeing she is a small dog anyway is to get her to go into a doggie litter box useing the same tacktic as to get her to go outside by moveing the piddle pads closer to the box untill its in the box them cut down the size of the piddle pad untill its completely gone and she is doing it by herself this will rid you of the hassle of looking over your entire back yard for poo and stepping in it and haveing to get a doggie door and all...your choice thou ..
