Amazon has PetSafe Pawz Away Instant Pet Barrier for $42.72 with free shipping.
Designed by professionals, this instant pet barrier system helps keep the family dog away from problem areas in the home--with no training necessary and no programming or installation required. Simply place the small, disc-like Zone transmitter in an area the dog should avoid like the trash, kitchen counter, or dining room table. Set the Zone's protection coverage area between 2 and 12 feet in diameter, then secure the included collar on the pet (fits neck sizes 5 to 21 inches). When the dog comes within the set "zone" the collar will admit a warning beep. If the dog comes closer, the collar will admit a small, electric shock. If the dog comes closer the level of stimulation will increase until the dog realizes the area is out-of-bounds. Unlike other deterrents, Zones provide completely cordless operation so they can be placed anywhere. [ Shop Now ]
