"Not made a scrap of difference. I can hear the slight whistle when it is activated, but it doesn't really stop the dog barking. The strap seems to go behind the device, and maybe it would be better if it was tight up against the dogs throat. It is hard to put it on and tighten it up, so I am going to modify it and see if it can be improved."
