The Animal Restraining Bolt served as a makeshift alternative to a droid restraining bolt, designed to manage animals and ensure they acted according to the rider's desires.
Its construction involved disassembling the Ion Pulse Generator components, substituting them with a self-filling auto-hypodermic unit, for instance, a MedCo Auto-6 Hypodermic Sleeve. The hypodermic was then loaded with a drug that induced pleasure, such as Pleezer or A Vrassa, and upon command, this substance would be administered to the animal, effectively rewarding it for desired actions.
