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. The receiver collar will work with as many Zones as there are problem areas. One Zone comes included with additional Zones available separately, each requiring three AA batteries for operation.

A replaceable 3-volt battery for the receiver collar also comes included. The 2-1/5-ounce receiver measures 1-7/8 by 1-1/6 by 1-2/7 inches, the transmitter measures 4-3/4 by 4-3/4 by 1-1/8 inches, and the system carries a limited lifetime warranty.
