Field trial horse must be able to be picketed or stand tied. The form of picketing in field trails is not the overhead type of set up. A stake is driven into the ground and attached to 20 or 30 foot of rope, cable or chain then it is run through a hose to attach to a heavy duty snap that is hooked to halter. Horses are tied out night and day when not in use. It is important that the horse be trained to be out on such a picket, they must be watched closely when first started to this form of tie out.
Some people use a nylon cow collar instead of a halter.
