yes I did generalize, I meant to say working and herding breeds dont do what they were bred for. and I know about those winners in the past 3 years because I watch the shows, look the winners up online and their breeding kennels, and have even requested info from the working and herding breeds clubs. and I guess that is also a generalization so let me clarify further, most of the working and herding breeds. I have done a lot of research on the winners of best in show and best in breed of: gsd, doberman, rottweiler, border collie, rough and smooth collie, old english sheepdog, malinois, australian cattle dog, and a few others. alaskan malamute, husky, samoyed, akita, mastiff, great dane, bullmastiff (last 3 would be difficult to do what they were bred for though), and some others. so no not all of them that I know of. but too many.
and no its not the akc's fault, though they do share some of the blame (get to that in a second). the individual breed clubs should preserve the breed and require them to do the work/job they were bred for. with the gsd yes the american gsd club is horrible in the way they allow breeders to breed for angulation and everything else.
the akc shares the blame in that...the judges of conformation shows are akc judges. the standard is known to the akc (for all breeds they accept) and yet they dont follow the standard with all of the dogs. yes with many breeds they do I am sure. (and earlier I didnt mean for companion and toy breeds to be lumped into that broad statement, they do their job, I meant dogs that are in working/herding categories). I use the gsd as an example because they have deviated so severely from the standard in the US. I dont mean it to sound as if I am only focussing on the gsd, just an easy target with this topic.
