I bought this item to house train my puppy. We live in an apartment and had pee pads in the bedroom and this right by the door. He learned to go straight for the pet park. Eventually we moved it onto the patio and he would wait at the door for us to open the door and go out on the patio. By the time he was 6 months old, he learned to wait by the door and then it was a mention to us that he needed to be brought outside. It was AMAZING for training!!
