Add Additional Pets to Your PetSafe Pawz Away Pet Barriers. The PetSafe Pawz Away Extra Receiver Collar can be used 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 Static Correction.
With a Progressive Static Correction, your pet will receive a mild correction on the lowest level when his is in the prohibited area. 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.
This static correction will not harm your pet, but will startle him with an unpleasant tingling. Your pet will soon associate this feeling with the prohibited area and stay away. This collar will fit dogs 5 lbs or more with a neck size of 6" to 28".
