We pick up after the pups outside up to 4+ times per day and always use the plastic shopping bags. That's a lot of bags being used. Sometimes we run out of bags and I have to open "used" bagsI was looking though the Dr. Foster & Smith catalog and came across the Doggy Dooley which sparked my interest. It seems like a good concept if it really works. Does anyone have one of these or something similar? I'd appreciate any positive/negative feedback. Or, any feedback on a different way of disposing of waste would be helpful as well.
