Abstract: An improved horse grooming stall utilizing tether devices on opposite side walls, each tether device having a spring-biased spool for controlling withdrawal and retraction of a retaining strap. A horse is groomed by latching the straps of the tether devices to opposite sides of the horse's harness to hold it essentially stationary during grooming without risk of injury.
