Abstract
A leash training device includes a leash cord (3) and a stimulus collar (4,6) coupled to an end of the leash cord. The stimulus collar includes a strap (4) adapted to fit around the neck of an animal to be trained or controlled, and an electrical stimulus unit (6) supported by the strap. The electrical stimulus unit (6) includes a stimulus circuit (16). A transformer (17) coupled between the stimulus circuit (16) and a pair of electrodes (5) for contacting skin of the animal. A measurement device (101) is coupled to the leash cord to measure tension in the leash cord and produce a control signal (106) when the tension exceeds a predetermined threshold. The stimulus circuit (16) produces a drive signal in response to the control signal and applies the drive signal to a primary winding of the transformer (17). The measurement device (101) includes a first connector (103) connected to the second end of the leash cord (3) and to a first end of a spring (34) having a second end coupled in a fixed relationship to a second connector (102) so that the spring (34) resists movement of the second connector (102) relative to the first connector (103).
