If you have two dogs being contained and you use the hand held transmitter to stop an undesired act by one dog, both dogs will receive stimulation. Hence DO NOT use this system with more than one dog. This also means that if your dog is out side of the containment your dog will NOT receive a stimulation. You cannot use the training feature outside of the perimeter of the wire. The wire perimeter must be less than 1200 Ft. of wire or less. More Information Scroll Down
500 ft. of wire is enough to cover around 1/2 acre of land. Additional boundary kits are available above. To figure out how much wire you need, click on the link below: How Much Wire Do I Need?
