Most wireless fences work to keep dogs over eight pounds in their own yard. Wireless fences are the simplest because there is no installation. It is a plug and go unit. Petsafe wireless fence reviews are extremely positive. It is an easy system to maintain. Owners of this system like that it is travel ready. It takes remarkably little effort to unplug the unit and be on their way. It works be emitting a static correction if the dog gets too close. This tells the dog to return to the “safe area.” The unit emits a signal roughly 90 feet in diameter. This equates to just over half an acre. A person who wants to keep their dog safe yet allow them some freedom would do well with this system.
