An animal training device for administering audio stimulus and physical encouragement to an animal. The trainer has a transmitter with variable signal strength. The animal worn device had a receiver that senses the signal strength. If the signal strength drops to a preset limit indicative of distance from the transmitter, a tone is sounded. Further signal drop results in a shock being delivered. Alternatively, a trainer module comprises an RFID poller and an animal module comprises an RFID tag. The poller sends a polling signal to the RFID tag. The polling signal is reflected back to the trainer module where the reflective signal is used to determine a separation distance. If the separation distance exceeds a preset threshold, an encouragement command is sent from the trainer module to the animal module.
