I've used the bells LOTS with training .
make sure the sting or whatever comes way down so they can reach it. if you think it's sto loud just keep a bell or 2 near the bottom. RING IT EVERYTIME you take them out to potty YOURSELF. I actually pick them up , take their paw and make themhit it before going out. It might take awhile but they willget it eventually. LOL On the other had...,,,LOL.. here is always a smartypants who figures out ringing the bell means going outside so she will ring the bell ALLDAY when it's warm out
