One thing I use is "The Pop". I taught Breeze to bark on command. And to stop barking on command to the word "Quite". So when we are out walking I normall have breeze on my left and will have the leash cross my body to my right hand with My left hand loosly holding the leash. I will say "Quite" ONCE when she begins to bark, then if she doens't stop I pull up with my right hand so the collar will gerk on her neck. The pull should only last for a second and should not hurt the dog, just let them know you mean what you are saying.. It's just a "Pop" you should be able to say "Pop" and the pull should be over.

I hope that helps and you understand, it can be confusing! If you have any questions feel free to ask!
