Wireless Dog Fences

Wireless dog fences use a radio transmitter that sends a signal out in a circle, with the transmitter at the center. A small receiver is built into a collar, and when your dog approaches the boundary set up by the transmitter, a warning noise is sounded. If the dog continues to approach, it will get a shock.

Wireless Dog Fences Have Advantages and Disadvantages

Ease of installation is a major advantage to wireless dog fences. All you really have to do is plug in the transmitter and adjust the range. A further advantage is that the system is portable, and can even be plugged in to your car's cigarette lighter. This is a major plus for campers and travelers.

However, there are also several disadvantages, and most sites urge you to call them before ordering to be sure that this is the right system for you. For one thing, wireless dog fences can only be used with medium-sized dogs, from 15 to 45 pounds. The collar is too big to be worn comfortably by smaller dogs, and larger dogs, or especially frisky medium-sized dogs, may be able to run through the boundary.

Since the signal is emitted from the transmitter equally in all directions, the only shape possible is a circle. Also, its effectiveness is limited if the area to be contained is hilly or irregular; it works best on flat yards. It is possible to use more than one transmitter, setting them up so that their signals overlap, to increase the size of the containment area. Finally, since it's unlikely that you'll be able to set up the transmitter in the middle of the area you want to permit to your dog, much of the containment space will be wasted.
