Good day! So Punkin has been doing pretty darn good with potty training (thank goodness) and now I want to work on getting her to ring a bell to let me know when she has to go out. Do you all have any suggestions on set up? i.e. where to place the bell, type of bell that works the best and has the best sound to be heard through the house, how high to hang the bell. Thanks for your suggestions....good gracious I'm such a noobie at this. lol.
