@jewels77 You can either turn barking into a cue. Which means that when it happens you can "cut it off." But it does involve treating the barking initially. This could work for you. And while you're working on it you can manage barking at sounds with a white noise machine. but for me I give my dog a treat when she barks or when I notice alert body language, which interrupts it and send her to her mat. We then do some relaxation work. She barks less now and has an easier time coming to me when I need her to move from the window. I did not have the experience where it reinforced barking because every treat after the first is only given if she reorients away from the source. It works for us because her barking happens when she looks out of the window.
