The Spray Barrier Indoor Pet Barrier System requires no training but provides immediate results. It's easy to use, too. Just plug the emitter dish into a regular household outlet and place it in area your pooch isn't allowed.As your pet approaches the emitter dish, the receiver on his adjustable collar will pick up the emitter's low frequency signal. After the collar emits a warning beep, the dog will receive a burst of stain-free, hypoallergenic citronella spray, thus correcting your dog without pain.
