Abstract: The invention is a calf restraining device which allows the user to singlehandedly restrain a calf for the purpose of treating medically or examining. Basically, this calf restrainer consists of a 56" length of 3/4" PVC pipe with associated parts and has a 3/8" nylon rope running through the pipe and doubling back to a handle end, outside of the pipe. This creates a larger loop at the handle end which enables the user to insert his hand and wrist therethrough prior to grabbing the handle end. A smaller loop on the portion of the rope outside of the pipe is retained at the handle end by a plastic, elongated, retainer washer which allows the user to slip the smaller loop from the handle end and let it slide down the outside of the pipe until it is stopped by the end cap. The loop so formed by this operation is similar to a lasso and can be easily slipped over a calf's head and a direct pull backwards by the user lets the smaller loop clear the end cap and results in the calf being restrained.
