Electronic fence capable of guiding animals to return

A training device that includes a receiver and that is worn by an animal for prompting the animal to stay within a confined zone, comprising:

• circuitry for receiving transmitted RF signals and control commands wherein the receiver initiates a stimulation based upon the control commands;
• circuitry for determining whether the animal is within a first boundary, between a first and a second boundary, and outside of the second boundary;
• a plurality of lamps for indicating selected stimulation modes;
• circuitry for providing sound for at least one stimulation mode;
• circuitry for providing a vibration for at least one stimulation mode;
• wherein, the receiver is configured to:
• based on one of the received animal control commands, determine whether to stimulate the animal;
• based on the animal's location in relation to the plurality of defined invisible boundaries, determine what type of stimulation to apply to the animal, wherein:
• a first stimulation is applied if the animal is approaching a first boundary from an internal first area surrounded by the first boundary;
• a second stimulation is applied if the animal has crossed the first boundary and is approaching a second boundary and is in an area between the first and second boundaries;
• wherein the first stimulation is not applied if the animal is approaching the first boundary and is in the area between the first and second boundaries;
• and
• wherein the second stimulation is not applied if the animal is approaching the second boundary and is in an area outside of the second boundary.
