Sheep Jockeys

Sheep, Sheepdogs and Toy Jockeys holding on for dear life on the back of the sheep...intrigued...come and watch sheep herdling jumps and laugh out loud.

On a more serious note:

A Sheepdog trial (also herding event, stock dog trial or simply dog trial) is a competitive dog sport in which herding dog breeds move sheep around a field, fences, gates, or enclosures as directed by their handlers. Such events are particularly associated with hill farming areas, where sheep range widely on largely unfenced land.
