Even in Germany, many of hte dogs who have HGH (large flock herding titles) are "show dogs" not true working daily dogs....most of the dogs who truly work daily, and win the national herding championship are still the working line dogs. I attended a show this past summer where Herr Wilfred Scheld officiated, and he presented a slideshow and short talk about herding, the dogs who were sucessful and what was needed to herd genetically...it was very interesting. We have one member here who herds the HGH style actively (phgsd) and she may be able to help you understand what is entailed. My one female line has been worked/tested on sheep and there is just very little opportunity for most to engage in this type training.
