Abstract
The whereabouts of a pet or other animal are controlled using one or more transponders to established a boundary. The transponders receive an incident signal from a transmitter and generate a distinguishable return signal which, when the animal moves into proximity of the boundary, is received by a unit affixed to the animal to initiate application of an aversive stimulus which deters the animal from traversing the boundary. The transponders can be active or passive and can be located to establish either fixed or mobile boundaries.
