Rudy can be the same way.

I got a soda can and put rocks in it. Taped the top shut so the rocks won't come out. Everytime he barks, we shake the can and at least for that moment he stops barking. He's afraid of the can's noise.
I did this outside one morning when the neighbor dogs were barking their heads off also. Rudy was right there joining along and I shook the can. OMG, they all stopped barking.

At least for a little while.
But we really haven't been consistent with that. Guess we should have those cans all over the house and yard.
Good Luck, girls.
