Containment systems give pets the freedom to safely explore their surroundings within a specified, hidden boundary. They work by sending a wireless radio signal from a transmitter to a receiver collar worn by the pet. An alternative to traditional fencing, dog containment solutions can be customized to fit the size and terrain of any yard.

How Pet Containment Systems Work

All hidden fences work generally the same way. Specific features may vary depending on the type of system.

  • A transmitter is installed somewhere in the home or garage. The transmitter controls a radio signal that is either sent wirelessly or goes through a wire buried several inches underground in the yard.

  • The dog or cat wears a special collar with a receiver that detects the radio signal. When the pet approaches the underground wire (or the wireless boundary), the receiver collar emits a warning signal.

  • If the pet goes beyond the warning signal, the receiver collar emits a static correction that is a mild, harmless electric stimulation. The pet experiences a light tingling sensation on the skin that gets his attention and interrupts his behavior.

training is key


Training is an important component of successful dog containment solutions. Hidden or “invisible” fences installed by dealers generally include training services. Any type of electronic containment system should come with adequate instructions for introducing your pet to the boundary. Teaching a pet to respect the boundary without fearing it typically involves these steps:

  • When a containment system is first installed, flags are used to create a visual boundary marker.

  • The pet gets a warning signal from his collar when he approaches the flags, helping him learn where the “fence” is.

  • Training conditions the dog to stop at the warning signal. Even after the flags are removed, most dogs stop before entering the zone where the static correction is issued.

Advantages of Containment Systems

Hidden or “invisible” fences have advantages for both people and pets. They are a less expensive option than traditional fencing and can be customized to fit the size and landscape of the yard. In neighborhoods with restrictions against traditional fences, in-ground or wireless containment systems may be a pet owner’s only option for safe, secure confinement. Most systems can accommodate multiple pets and offer separate settings to fit the individual temperament of each one. When pets are properly trained to stay within the containment area, attempts to escape are rare. Unlike conventional fences, there are no worries about open gates or pets digging or climbing out of electronic dog containment solutions.
