Wireless and Electric Dog Fence Systems now Available

One of the hottest things in the pet industry these days is the invisible fence.  There are two main types of invisible dog fence systems out there.  There is the electric dog fence system that uses wire that you bury in the ground around the perimeter of the area you want your dog contained in, then there is the wireless dog fence system.  These systems use state of the art technology to set up boundaries and establish containment.  Both types of fences are very effective and humane.  The can cover many acres of area, with extra wire and accessories, and are much safer than letting your dog roam wherever he pleases.   There are even products out there that take the place of dog crates or kennels.  Each person has his/her own opinion about electronic products for their pets.  I suggest you do some research and base your opinion on that research.
