Herding is a centuries-old canine occupation that has a long
tradition in Great Britain, home to this collie and its herd of
sheep. As with all working dogs, yet even more so with herders,
these dogs must not only be good at their task, but they must
easily develop a close collaborative friendship with their human
bosses. They must also be undaunted by much larger animals that
might kick or trample them if they're not vigilant. Bred for
stamina, herding dogs work with their masters all day in the
fields and take verbal orders from a distance.
