How does it work? When a ewe strains, her neck drops and her back arches. This pulls the cross webbing of the harness tighter against the vulva and also pulls the retainer (if one is used) into the ewe. Most ewes soon cease to strain.
Attach neck strap at base of neck and tighten so it remains comfortable.
Place tail through top hole (vaginal opening just appears through lower hole).
Take the rear leg straps and pass between the ewe's back legs, one on each side of the udder and snap into buckles on back strap (ensure that you do not trap the udder). Tighten the leg straps so they grip firmly.
Push the prolapse back into the ewe (contrary to the photo above, we strongly advise wearing gloves while doing so).
Adjust back buckle so the ewe cannot strain or push.
Check tension regularly to avoid chafing and manure build up.
Although it is possible (in most cases) for the ewe to lamb with the harness in place, we suggest that the harness be removed immediately prior to lambing.
