Promising review: “I’m usually pretty skeptical about things like this, but the first time I tried it, it worked immediately. The video says it only works on one dog at a time.” I personally would disagree just because I have 4 dogs that bark uncontrollably sometimes, especially when people come to my house. I picked up this dog bark stopper, pressed the button with the flashing light, and instantly my 4 dogs stopped barking. This product is much better than those shock collars. You can only use one of these collars per dog. I only had one of them. Plus, I hate using them on dogs. This is a great deterrent. It’s amazing how quickly it works.” —Stacey Adams.
