I have not used one but I have heard from other people who have tried them and they swear by them. I also heard that sometimes it is not an "instant" fix but that if the dogs wear them more than a few times, it gets better. Good luck. I would check what the return policy is at the store and if you buy it and it doesn't work, then see if you can return it for either store credit or money back.
