Ok try this it was our fall back recommended method from daycare when regular training doesn't work. It requires a little extra effort but worth it
The potty gods!!
Make a shake can a pop can with a few coins or metal screws inside. Secure the top by taping over it very well with duct tape.
Watch her ALL the time when she is out of the crate but don't let her know you are watching
This may mean less out of the crate time for a bit btw.
Keep a shake can close by any time she is out. As soon as she starts to squat, throw the can at her. ( don't hit her or at least not hard) it makes a very loud sound. The important part is that she doesn't know YOU did this if you have to hide behind a conrer , so be it. Then walk in take her right out amd prais and treat outside immediately after she goes. If s he won't gp while you are out, come back in and repeat the process.
The main reason you want her to think " the gods " did this os that she won't get in the habit of just doing it when no one is around. Also otnis VERY important that this os consistently used. Try not to let her have accidents while you aren't watching
You want her to NOT Want to go in the house because everyone time she tries, thisncrazy thing happens out of nowhere
It works very quickly if you are consistant
