Abstract: An apparatus for controlling the movement of an animal using an integral collar and self-retracting leash apparatus. According to the invention, an elastomeric cord is attached to a strap, which is adapted to be secured around the neck of an animal. In the preferred embodiment of the invention, the strap encloses the fixed end of the elastomeric cord, which is attached to an anchor located near the first end of the strap. The cord extends from the anchor in a direction substantially parallel to the longitudinal axis of the strap and passes around about 180° of a pulley or spool located near the second end of the strap. The cord then extends from the pulley in a direction substantially parallel to the longitudinal axis of the strap to an opening located near the first end of the strap. The free end of the cord passes through the opening in the strap.
