Daisy is 15 months old. We thought we had her trained, but over the past week or two she has pooped on our area rugs a couple of times. We have hardwood floors and tile and she never poops on that. But she went on the area rug in the living room, so we removed that rug. Guess what? She moved over to the area rug in the den and pooped on that. She also will poop on the basement wall to wall carpet, although we generally keep her out of there. We are prepared to remove all area rugs but would rather not. We do use Nature's Miracle when we pick up the poop, but it doesn't stop her. She is outdoor trained only - no pads. Any advice?
