It should...It will poop on the floor, or sometimes it will turn around and cry, or sometimes it will beep at you when it's perfectly fine. You have to praise/time out at the right times and they will get a bar. I think after they poop on the floor you have to give them time out within 15 minutes or they don't get a bar. Also, if you see it trying to poop on the floor, select the toilet icon to give it a toilet and potty train it
