Why should I purchase a DogWatch Hidden Fence System® over the Invisible Fence® brand?
DogWatch® is the only underground fence system that works on an FM radio signal frequency. This frequency system, called SafeLink, is an exclusive patented DogWatch® technology that provides your pet with the maximum protection from unintentional stimulation caused by stray radio signals. Other pet containment systems, such as the Invisible Fence brand run on an AM radio frequency that may pock up signals and can cause your dog to receive a correction when not near the hidden boundary. This may cause your dog to become confused and afraid. Only DogWatch’s SafeLink system safely ignores AM radio signals.
