Brian, thanks for the info from Ulf, must say I already knew this but it is good to hear it confirmed from somebody with a pedigree like Ulf.
Jackie, the only thing we disagree on is that the extreme angulated dogs could dominate but for the reasons you have given....a major reason you don't see more of these dogs on sheep is because it takes a dog with strong temperament to herd sheep. That's why I always rolled my eyes in my head when I heard American Show breeders trying to spin the extreme angulation makes the better herders. The temperament of these dogs, would make most of these dogs, too weak to control a large enough flock to get an HGH. So, I knew they were talking out their dreams and not something proven, just as the equation of extreme trotting being good for herding abilities.....there's no proof, no significant examples, and shows the lack of knowledge of the breeders trying to justify these dogs as being correct. I know you realize this Jackie, but how is it that a Judge can buy into this fairy tale logic???
