Many pet owners use an electric dog fence to boundary train their dogs. If the dogs get too close to the fence they get a low current shock that sends them back onto their own property. This is the best training aide for dogs that are prone to wondering off of the property. How it operates is simple the dog wears a collar that has a transmitter the fence has a receiver. When the two come in contact the dog gets a slight shock. The shock does not get hurt it just deters them from wondering off.
There are two types of electric dog fences one is a fence the other uses receivers that are installed around the property. The fence can either be temporary or permanent depending on how quickly your dog learns.
