What distinguishes stocks from other restraint devices for horses?

The distinction of stocks from other restraint devices for horses primarily lies in their design to partially immobilize the animal. Stocks serve the purpose of confining a horse safely while still allowing some movement. This partial immobilization is critical for applying veterinary care, grooming, or performing any required procedures without risking injury to the handler or the horse itself.

While other restraint devices may aim to limit the animal's movement, stocks provide a controlled environment that secures the horse in a way that reduces stress while still allowing access for care. This feature is essential in comparison to other types of restraints that may not offer the same level of stability or safety for both the horse and the handler.
