How does an electric dog fence work?

An electric dog fence is basically a boundary used to keep dogs within a certain distance without the use of a physical fence. When the dog comes close to violating the boundary, an alarm in the dog’s collar goes off. If the dog decides to ignore the sound, he gets a small shock through a specialized collar he wears.

In some electric dog fences systems, the actual “fence” is a wire buried underground.  This wire emits a radio signal to activate the light collar on the dog when he approaches the wire. Other systems use a central unit that emits a radio signal when the dog moves closer to an assigned radius from the central unit.

Other systems use GPS, which uses the technology to set the fence boundaries. This system is not so accurate, however, since GPS location can be inaccurate.

The collars that dogs wear are usually light and the intensity of the shock can be adjusted, leaving the highest ones for bigger, stronger dogs. The mild shock is only strong enough to surprise your pet and stop his movement, but it will not harm him in any way.
