puppylucy...you can teach her to ring the bell....and then you can take her to go potty outside. if you want to teach her to go outside. lol. we lived in a townhome (no backyad) and we hung the bell on the front door. gruffi would ring it and we would have to put his leash on him to take him to the front yard area.
its a great way to teach your dog to not run outside. like whenever i would take him out, he'd have his leash, and i'd put him in a sit-stay and if he would get up when i would open the door...i'd slam it. tell him to sit stay.
it takes about a week for them to fully understand that they have to sit-stay while you step outside first...and then they can follow. and then i would teach sit-stay while i would close the door. LOL. i was really strict with him.
not anymore though
