A shock collar works best. The bark collars work but not near as effective as a shock collar. I had a Fila Brasileiro once that barked til the batteries went out on a bark collar. I think it stimulated her. I went to a shock collar.

She would bark and hell would rain down on her. It only took a few zaps and she stopped barking. Funny thing is I had to put a dummy collar on her afterwards. With no collar she went back to barking. With the dummy collar she clammed up.

Hope you can control the barking. I live off the road and the barking at the dogs is not that big of a deal. If neighbors are close or if the dogs are close to the house then barking can be a much bigger issue.

Great you two made communication.
