Disclosed herein is an animal training device and method of controlling the same. The animal training device includes a transmitter and at least one receiver. The transmitter transmits RF signals according to manipulation of function switches, and has emergency stimulation mode in which an RF control signal is transmitted by adding a predetermined level to a low-frequency stimulation level set for each individual animal, simultaneous stimulation mode in which an RF control signal is transmitted by adding a predetermined level to low-frequency stimulation levels set for animals, and constant stimulation alternation mode in which an RF control signal is transmitted by automatically varying a period of a low-frequency stimulation. The receiver sets low-frequency stimulation for a corresponding one of the plurality of animals in response to the RF signals, and selectively performs operations corresponding to the emergency stimulation mode, the simultaneous stimulation mode, and the constant stimulation alternation mode.
