You might try the choke collar and put a long leash on it. Before you put the long leash on it put the clip through the handle part so that you have a big loop. put the loop over one of your shoulders and threw your other arm, then attach the collar to the dog. Now play fetch. This will make her wait for you to tell her to retrieve the dummy/toy/bird. Start without the big bang (gun shot, probly after a week or two dont rush it). This has worked for every dog ive trained. Hope it helps. Doing this you have two free hands one to use to wrap around the dogs mouth...using whateve command you want to stop the barking. i use quiet..if need be while your hands are wrapped rub her lips up and down on her teeth. Persistance pays off. Any questions let me know.....
