Invisible Wireless Fence For Dogs

Invisible dog fencing, also known as a pet fence or a fenceless boundary, is the best way to fence in a yard where your dog can play safely without creating an obstruction of your view. The way the invisible dog fence works is pretty simple; a wire is buried underground around the perimeter of your home. The wire carries a radio signal, which is received by a lightweight collar your dog should have on whenever he is outside. When the dog nears the boundary, the collar emits a warning sound, activated by the radio signal emitted from the buried wire. At this point, most dogs will back away, realizing they are too close to the perimeter. However, if the warning is ignored and the dog crosses the boundary of the fence, he will receive a very mild electric shock.
Invisible pet fences are safe for families with children, as they only affect animals wearing the receiver collars. However, it is important that you never cross an invisible boundary line holding an activated collar in your hand. Although most common around the homes of families with dogs, invisible animal fences can also be used to contain livestock in circumstances where ordinary agricultural fencing is inconvenient or illegal. This is true on British common land.
Some invisible dog fences are entirely wireless. Rather than using an underground wire, they emit a radio signal from a central unit. The central unit senses when the dog is too far away and sends a warning signal beep to his collar. If the dog ignores the warning and continues to travel away from the central unit, he will experience a mild shock. Another version of the wireless collar uses GPS signals to determine proximity to a predetermined virtual fence. With this product there is not need for any physical installation, which allows some additional flexibility and also makes it easier to change the boundary locations at any time.
All invisible dog fences come with variable setting on the shock collar. Larger dogs require a higher setting in order to be corrected, whereas small dogs may be hurt by those settings. It is important to read the instructions carefully and make sure that you set the collar at the lowest effective setting for your dog's weight and size. Some kits also come with boundary flags so landscapers and utility workers won't accidentally dig up the wires while working in your yard. Most systems also sell additional collars separate from the fence kit so you can control multiple dogs within the boundaries of your invisible pet fence.
Critics of invisible fencing often make claims that the practice is inhumane and can hurt your dog. This is not true as long as you follow the directions and be sure that you have set the shock level on the lowest possible effective setting. Most dogs will only need to cross the boundary once before they have learned their lesson and thereafter will be sufficiently controlled by the warning beep.
