This is Daniel's question: "Why are those breeds so much better at Sch. and not others, like border collies? There's a strong prey drive in all of them..."
Welll, border collies were bred to herd ONLY. Just like Australian Cattle Dogs, they were bred to herd and have EXTREME prey drive, but you'll never see one competing in Sch.
You take a breed like a German shepherd; they were bred to be an all working dog. Meaning herding, bomb/cadaver sniffer, seeing-eye-dog, police dog, etc. They're Extremely versatile.
Rottweiler: protection.
Doberman: protection.
Belgian Malinois: protection/police dog- actually, pretty much same as a German shepherd.
