Review title: Bark Control Review
Product review: We saw this product work at someone else's home when our dogs were also there. The barking of four dogs was quickly controlled. However, after purchasing for our own home, it only actually worked on one of our chihuahua's. Our other chihuahua would get angry at it and bark at the controller each time it emitted the sound. That put undue stress on our other chihuahua (the one that didn't bark) -- so we had to remove the batteries.
