All underground fences use radio frequencies to transmit the signal from the Hidden Fence wire to the receiver worn by the dog. Only DogWatch uses digital FM SafeLink® technology. The FM signal is less prone to interference and stray signals than the AM systems used by all other brands, including Invisible Fence®.
Every Dealer-installed DogWatch Hidden Fence comes with a Lifetime Equipment Warranty. You never need to worry about replacing your system in case of a lightning strike (we provide the best lightning protection, too!) or other mishap. We’ll even replace the receiver if the dog chews on it!
The DogWatch Hidden Fence is the only Consumers Digest ‘Best Buy’ rated a Premium Selection in the underground pet-containment category. The DogWatch Hidden Fence has been recognized as a ‘Best Buy’ in each of the five reviews of underground pet-containment systems that Consumers Digest conducted since 1998.
