Have you changed her eating and drinking schedule or location? Are you still systematically taking her out or bringing her to her elimination station 10 minutes after each meal, drink, sleep or play session and not going anywhere until she's gone potty?
Do you keep her attached to you with a leash while you're home so that you can keep an eye on her every move?
Has your pup ever been in a crate? If not, what are your reasons for not getting her used to a crate? (and yes, crate training and potty training are related.) If yes, why did you stop?
