A method of animal corralling and tracking includes: implanting an electronic device within an animal, the electronic device comprising one or more processors with non-transitory memory； receiving, with the electronic device, a GPS (global positioning satellite) signal defining a current location of the animal； selecting, on a digital map, acceptable GPS coordinate locations forming one or more geographic regions with one or more perimeter boundaries； wirelessly programming the electronic device with the selected acceptable GPS coordinate locations； wherein the electronic device non-transitory memory is programmed to: determine if the current location of the animal is approaching the one or more perimeter boundaries, outside of the one or more perimeter boundaries, within a predetermined distance of the one or more perimeter boundaries, or at the one or more perimeter boundaries； and electronically prodding the animal, using the electronic device, based on the determination.
