Our little girl was difficult. She just wasn’t signaling when she needed to go. And seemed not to understand the connection between going and going outside. We finally got a “potty bell” (online for about $10) affixed it to the wall beside the door and trained her to use it. We rang it, then took her out. Soon she was ringing it to be taken out. Then when she (did business) we gave her a treat and praised her. We always used the same command.... do business. Soon “she connected the dots” and now rings to be taken out to do business and get a treat. We are delighted with her. This works great. We even got a second one, attached it to a weighted post (at the same height) and now have a portable potty bell to take with us when we go away to visit friends. Good luck.
