Review title: Made Him Mad
Product review: Our chihuahua, who never barked unless people were knocking on the door, but as this was annoying we decided to purchase this for those few minutes of barking a day. It made his barking worse. Every time it went off (and I know it did because I could hear it) he would whine and then bark at it. Eventually the whining stopped and he would bark set it off and then go on a barking rampage.
