Title: Did not work
Review: I bought this but unfortunately it did not work on my 4 month old lab mix at all (he is 26 lbs). He ignored it the whole time, or just did not hear it. It stopped my 3 year old dachshund the first few times I used it, but after that he did not bother with it. Our next door neighbor's Rottweiler also simply ignore it.The only thing it seemed to do was drive my cats crazy. My guess is that it only really works on really small dogs.
Is the review positive or negative?
