Something like this was originally invented for boaters who were going to be out all day to give their dogs somewhere to go. I've thought about something like this for Jasper, who seems bound and determined to pee indoors on the carpet every time I leave him home, but I would have the smae problem that I have with the puppy pads....he stands on the edge and lifts his leg....the pee all lands on the carpet!! *Scowl*
