Wireless Dog Fences create a circular boundary around a central base station using radio waves. They are quick to set up, but are not yet anywhere near as good as in-ground (wired) dog fences. The units have a lot of trouble going through obstacles, particularly a metal roof, siding, trees, and some walls. They are also imprecise, with even the best system, the boundary will move 3-5 feet second-to-second. The units can also be slow to respond, meaning the dog can get the correction too late and can keep getting the correction for a few seconds after they return.
One can obtain wireless electric fences for dogs at shops like Petco, Petsmart, Petsafe and many others. They are even available at Amazon or Ebay.
