We were sitting out in front of the cottage watching the sheep grazing in the field across the road, when suddenly we saw a flash of black fur running towards them, and they all turned and ran off to the left... By the time we grabbed our cameras and ran down the driveway, that little dog had wrangled them all into this spot, where their human was setting out their breakfast... I'd seen seen herding trials, and the dogs working behind the scenes guiding groups of two or three sheep between their holding area and the various competition/testing rings; and my dog and I have been learning to play Treibball, a game using herding commands/techniques to basically play doggie-soccer/football with those big "fitness" balls (which I think amused the shepherd) - but this was the first time I'd seen actual real-world sheep-herding. :D
