Abstract: A unit adapted to be worn by a dog or other animal acts under the control of a remote control unit to produce stimuli including an aversive electrical stimulus followed by a characteristic sound or other second stimulus in a relation conditioning the animal to have safety, relief and relaxation responses to that second stimulus. A different sound or other third stimulus is preferably produced just prior to the onset of the aversive electrical stimulation, and becomes a conditioned warning stimulus to the animal. The remote control unit is actuable to cause production of these three different stimuli in sequence, to condition the sounds to the desired responses, and after such conditioning can produce the two sounds independently and without aversive electrical stimulation to control the animal's behavior and facilitate training of the animal.

Abstract: In order to train a dog not to bark, a device attached to the dog's collar emits a characteristic sound whenever he barks, which sound may be accompanied on some occasions by a light electrical shock acting to condition the dog to dislike the sound more than he otherwise would.
