Abstract: A control device and method controls an animal's location. A GPS receiver and a processor determine the position, velocity and heading direction of the animal relative to a target. A stimulus unit selectively applies a stimulus to the animal. If the position of the animal relative to the target is less than a predetermined distance and the animal's velocity relative to the target is within a predetermined range and the heading direction of the animal is within a predetermined orientation relative to the target, then a non-aversive stimulus is applied to the animal, and removal of a non-aversive stimulus is selectively effected when the animal's velocity relative to the target is outside of the predetermined range, or the heading direction of the animal changes by more than a predetermined amount, otherwise the non-aversive stimulus is first removed followed by application of an aversive stimulus to the animal.

Abstract: A control device and method is taught for controlling an animal's location. A GPS receiver receives GPS signals and a processor determines the position, velocity and heading direction of the animal relative to a target. A stimulus unit selectively applies a stimulus to the animal in response to received signals.
