Teach Your Pet To Avoid Areas in Your Home. The PetSafe Pawz Away Indoor Pet Barrier Transmitter will broadcast a radio signal from 2-12 feet. Your pet will wear a collar that will deliver a mild correction when it comes into this signal range. When your dog first enters this range he will receive an audible tone followed by mild stimulation that will increase the closer he gets to the transmitter. The fast, easy, no-training way to keep your dog from problem areas. Unlike other deterrents, the PetSafe Pawz Away Indoor Pet Barrier Transmitter is totally cordless. You can put a transmitter near anything you want your dog to avoid - the trash, kitchen counter or fine furniture. Adjustable Barrier range protects areas from 2-12 feet in diameter. Battery operated Barrier fits easily in small spaces. Only 5 inches in diameter. Easy set-up and training.
