The Wireless Dog Fence is a revolutionary new concept in dog fences and provides the simplest form of pet containment ever. Wireless systems emit a radio signal, from the transmitter, around your home. Your dog wears a lightweight receiver collar which listens for the signal. While it’s receiving the signal, your dog is free to run and play. When it approaches the boundary of the signal area, the collar receives a warning beep. If the dog continues to challenge the electric dog fence, it receives a light correction which is startling but not harmful. With a little training, your pet quickly learns the boundaries within the wireless dog fence. Setting the boundaries of your yard takes only a few minutes. Simply adjust the range setting on the transmitter, from a radius of just a few feet - up to 90 feet. These dog fences have no unattractive poles to set up and no wires to bury in the yard.
