Title: Life saver
Review: This device is a real life saver.The next-door-neighbor's dog liked to bark, night and day.I couldn't sleep, it was driving me crazy.Within a couple days the dog learned to stop barking.In fact, I hardly had to use it - maybe once a week when someone else from the neighborhood got too close to the neighbor's house & the dog couldn't control himself.Very glad I purchased this dog training aid.
