Abstract: An animal training device comprises a housing which is designed to be attached to an animal collar at a point on the collar diametrically opposite the point where a leash may be attached. The housing has a rear face, adjacent the neck of an animal when it is worn on the collar of such animal, and a front face. At least one pair of electrodes extends from the rear face of the housing; and a pressure sensitive transducer is located on the front face of the housing for engagement by the collar. An electronic circuit is located in the housing; and it is coupled between the pressure sensitive transducer and the electrodes to provide electrical stimulus pulses of varying intensity across the electrodes in response to changes on the pressure sensitive transducer, once the pressure crosses a pre-established threshold.
