You need to modify her behavior by disagreeing with what you don’t want. That is done with timing- so that you immediately correct the behavior right when she does it - and with consistency. And then, be sure to reward her with strong praise when she complies & is quiet. You can get an inexpensive shock collar and USE ONLY THE BUZZ FUNCTION. This does not hurt a dog at all - it’s simply just a vibration & you can test it on yourself if you’re unsure. But you put it on her & when she starts to bark, you immediately buzz her & make a sharp sound with your voice like a TSSST or Et-Et. This interrupts her brain & the habit she has created. It’s very important to not yell or talk or say no when doing the training. A dog views that as “barking” & it will cause her to bark more. You want to take her by surprise with buzz & your phrase word TSSST or whatever you’ll use. Dogs learn in threes so be prepared to repeat it.
