An automatic animal retrieving platform assembly (10) and its method of operation for retrieving a domestic animal (12) from a stall (29) is described. The platform assembly retrieves and at least partly confines the domestic animal from a stall to effect a job function with the animal, such as for milking a cow in a dairy barn. The platform assembly (10) is displaceable on wheels (13) to position an entrance opening (24) thereof behind the animal stall. A displaceable floor (17) extends to the rear of the stall and retrieving arms (26, 27) are provided to grasp the animal and cause it to back-up slowly onto the displaceable floor where it is at least partly confined in a cage 18. After the job function is completed the retrieving arms (26, 27) release the animal and it returns freely to its stall. To help it return to its stall a tether (70) may be secured to a neck collar 30 of the animal.
