Title: Works!!
Review: I have 2 chihuahua's. They are yapper's. Every time we go into the back yard they take off to the fence at start barking at neighbor and dog. I do a quick push of the button and give the command "enough" and they stopped. I only had to do this twice to get the point across. One of the dogs in particular responded 100% to this. The other one responds but it doesn't affect her as well. Overall, the product works just as it says it will.
