Safelink™ FM Technology

Extended Battery Life For Greater Safety and Consistent Performance!
DogWatch is the only Hidden Fence System that uses an FM radio (fences from all other pet fencing brands use AM radio) signal. SafeLink provides your pet with the best protection against unintentional stimulation from stray radio signals (e.g., garage door openers, televisions and computers). Police, fire and aircraft equipment all use an FM system. SafeLink is more safe and secure for your pet.
