One of the last events we attended at the Celtic Fling was the sheep dog demonstration. The owner, I can't remember his name, comes from a historic farm in New Jersey. He competes professionally at events around the world. The dogs are bred to herd sheep, but they do require long training. The first dog, Jenna, came from England, where she was trained. These dogs need to work and be challenged on a daily basis. They probably wouldn't make good pets for most families. They sure are fun to watch!
