I agree with using an xpen lined with piddle pads. Start by supervising her in the pen as much as you can. When she goes potty on the pad, praise her like she just performed the best trick in the world. Give her a small treat like a single kibble.

Then start removing the pads until you are down to one.

Or use one pad in the xpen, put her on it at least once an hour (while you are awake) and use key phrases like "Go potty." She may not do it, but keep up the routine.

When you catch her going potty in the wrong place, say "Uh oh!" and put her on the pad and use the key phrase, or say "Potty here."

Always praise when she gets it right and don't be angry when she gets it wrong.

When you have her out of her xpen, playing or for whatever reason, keep the pad really close by.

Good luck!
