Abstract: A remotely controllable dog muzzle apparatus includes a cup-shaped snout shield to which is attached an accessory pod provided with stimulus generators such as a stun gun or sensors interactive with a physical environment of a dog fitted with the muzzle. In the preferred embodiment, the pod contains a stun gun having a pair of forward projecting electrodes, and a high voltage power supply having an ON/OFF control terminal connected to an electronic switch controlled by the demodulated output of a radio receiver. The apparatus includes a remote radio transmitter adapted to transmit coded signals on a modulated radio frequency carrier to the receiver, thereby actuating the electronic switch and causing high voltage electrical sparks to arc between the electrodes, the sparks encouraging a suspect to obey orders or have pain inflicted by the electrodes.
