A piezoelectric shocking device for training an animal to alter or avoid particular behaviors such as pulling on a leash, pressing against a fence, or in the instance of a horse, cribbing or wind sucking. The device includes an inner housing for receiving internal components, and an outer housing for receiving the inner housing. The inner housing is nested within the outer housing in a sliding fashion. The internal working components of the device include a piezoelectric ceramic crystal which, when struck with sufficient force, generates an electrical pulse. In order to capture this electrical pulse, electrical contacts are positioned on either end of the crystal and in direct contact therewith such that a force exerted on either electrical contact is transferred directly to the crystal. A hammer is provided for striking the first electrical contact with the force required to generate an electrical pulse. An energy storage spring is provided for storing potential energy which is released to propel the hammer toward the crystal. A return spring is provided for returning the hammer to an initial position away from the crystal. As the inner housing and outer housings are pulled away from each other, the energy storage spring is compressed, storing potential energy. When the potential energy has reached a level sufficient to disengage the hammer collar from the crystal receptacle shoulder, the hammer is thrust toward the first electrical contact. When the hammer strikes the first electrical contact, an electrical pulse is generated by the crystal and is transmitted through the first and second electrical leads and the hammer is returned to its original position by the return spring.
