This could be unusual to border collies. Ranking canine intelligence is a sticky business; Dr. Coren, for his book, ranked the dogs on their "working and obedience intelligence," testing how quickly each breed could learn a command and how consistently each could demonstrate that knowledge. The border collie ranked highest, and the Afghan hound the lowest, but Coren is quick to note that intelligence is not any one thing, and that his ranking only applies to, basically, ability to respond to commands. The beagle, for example, ranks seventh from the bottom--a pretty dumb breed, according to the list. Yet these types of commands don't play to the beagle's strength; a member of the hound family, the beagle was bred as a hunting dog, trained to perform one task. Beagles are single-minded and determined, when tracking down a scent, but that was all they ever had to do--it was never necessary to understand and distinguish between multiple verbal commands. A border collie's job, herding, is complex: move this sheep from this place to this place, keep a herd in a certain area, separate one sheep from the herd, divide the sheep into multiple groups, bring individual sheep to the herder. "Intelligence" doesn't mean much, really; all way can say for sure is that border collies test extremely highly on a certain kind of obedience test.
