oooooo boy, I am the LemonLauren with the little "stinker" named Nikko :-) We actually officially call him "turdbrain," but I guess that's just semantics. I totally understand your problem, and am happy to commiserate with you.
At first, we ignored bell-ringing when we were pretty sure Nikko didn't have to pee/poo. At 4-5mo old, this resulted in peeing in somewhat hidden places along the edges of our living room, and we officially regretted ignoring his bell ringing, and we made some major changes to help rectify the situation. So please, at the very least, don't ignore the bell ringing, as abusive as it might become. And I know how ridiculously annoying and frustrating it can be, really.
I honestly don't have any awesome magical solutions yet, as Nikko is only 6mo old right now, but we have found a few tricks and halfway solutions to at least help him to become 31 days now without any indoor accidents... and to cut back on the bell abuse. But Nikko is still unfortunately a bell abuser of sorts. We've just learned to adapt a little ourselves, to make our life a bit easier, and to somewhat cut down on his abuse.
I'll help as much as I can, if you can give me some more info.... How old is your pup? Do you have a fenced in yard? Is she already housetrained, and is just learning the bell, or is the bell training happening in tandem with housetraining? Does she have the bell by a door that is only used for potty, or is this door also used for other things (like going for walks, car rides, people entering and exiting your residence, etc.)?
