Abstract: A programmable boundary pet containment system is provided for controlling the access of animals to areas outside of programmed boundaries. A programmable relay collar is provided on an animal to transmit positional data as detected from positional satellites to a remotely located processing station. The processing station calculates the relayed data to determine the position of the animal relative to a configuration data file establishing confinement area boundaries. Animals that are detected as venturing beyond the programmed boundaries are subject to a correction stimulus, such as a mild shock or audible signal, delivered to the animal by the relay collar as enabled by the remotely located processing station.
