Claim:
An animal behavioral control apparatus, comprising: a cartridge containing pressurized gas; a housing surrounding at least part of the cartridge; a head connected to the housing, the head including an actuator and a valve, the valve engaging the cartridge upon actuation of the actuator to release gas out of the cartridge and through an outlet port of the head; and an extension assembly connected to the head to receive gas from the outlet port, the extension assembly including a body, a flow restrictor located at least partly within the body, and a spring located at least partly within the body, wherein, during use, the spring biases the flow restrictor in a seated position to close a bore of the body, and wherein, upon actuation of the head, the released gas causes the flow restrictor to move to an unseated position against the biasing of the spring to open the bore, and gas flows through the extension assembly, and the animal behavioral control apparatus ejects a blast of gas out of the extension assembly, the extension assembly further including a cap located at an end of the body, the cap having an outlet orifice for ejecting the blast of gas, the outlet orifice having a diameter that is less than that of the bore.
