Add Additional Pets to Your PetSafe Pawz Away Pet Barriers. The PetSafe Pawz Away Extra Receiver Collar works with the PetSafe Pawz Away Outdoor Pet Barrier or the PetSafe Pawz Away Indoor Pet Barrier.
This dog collar is lightweight, waterproof and uses a progressive correction to train your pet. If your pet approaches an "off limits" area, will receive a mild stimulation. This stimulation will increase until your pet backs away from the area. If your dog returns to the forbidden area, the collar will correct him again, beginning at the lowest level. Your pet will soon associate this feeling with the prohibited area and stay away.
