Title: Great for certain dogs
Review: Here's the deal --- Bought this for our ShiChon and it works like a charm. LOVE it!Two years later we get a Yorkie and the Yorkie doesn't even flinch when we press the button.Luckily -- it still works for the other dog.So - I'm guessing it depends on the dog and their range of hearing... and maybe how high pitch their bark is too!
