The Rugby pelham is a bit mainly used for showing young horses where two
reins will be used in future classes, but the horse has not yet been introduced
to the double bridle. It can also be used for small mouthed horses who are
uncomfortable with a double bridle. It is basically a pelham, but with the
snaffle ring on a short link, to give the illusion of a bridoon coming out from
the mouth next to the weymouth. A slip head is normally fastened to the snaffle
links, to complete the illusion and make it look like the horse is wearing a
double bridle.
