Title: GREAT collar!!
Review: We have a 10 month old barking Sheltie. It only took 3 or 4 zaps with the shock set on 4 out of 10 before she realized that barking at everything that moved is not an option. I gave her the tone first and then the shock. Now all it takes is a beep and she knows what is coming so she quits. She also avoids the one area of the yard that gets muddy. I love the fact that I contol the correction. We have a big yard and I can reach her no matter where she is. I love this collar and our nieghbors are enjoying our dog!! Amazon has the cheapest price I found.
