An animal training apparatus with multiple receiver control function is disclosed. The apparatus comprises a single transmitter and multiple receivers corresponding to the respective animals. The transmitter includes a plurality of level adjustment switches for setting shock levels of the respective receivers. When the volume of a level adjustment switch corresponding to a desired receiver is changed, a transmitter control unit stores a shock level data into a memory. An ID code corresponding to the receiver is attached to the shock level data of a selected receiver. The shock level data with the ID code is transmitted to the receivers. The receivers receive an RF signal that includes the ID code and shock level data, and generate electrical shock to be applied to the animal when the received ID code is identical to a stored ID code.
