ZND-1000 EXTRA ZONE FOR ZND-1200

Designed by professionals to instantly keep your dog away from problem areas in your home-no training necessary. You can put a ZONETM near anything you want your dog to avoid - the trash, kitchen counter, dining room table, baby's crib or protect your fine furniture. Your dog's collar safely reminds her that this space is off-limits. Each ZONETM requires 3 AA batteries, not included.
