A boundary control device, a boundary control system, and a method of conditioning the behavior of animals are provided. The boundary control device includes a base member configured to be positioned adjacent a boundary, a sound emitter coupled to the base member and configured to emit a sound upon activation, a light emitter coupled to the base member and configured to emit a light upon activation, and a boundary sensor coupled to the base member and configured to sense an object disposed adjacent the boundary. The sound emitter and the light emitter are activated upon sensing of the object by the boundary sensor.
