For the last 12,000 years humans have used dogs to help get their work done. One of the jobs that people first taught dogs was how to tend and herd sheep, goats, and cattle. Today’s sheepdogs include several breeds. Collies, shelties, and Old English sheepdogs are all dogs that people have bred to herd. If you’ve been around these dogs, you know they like to herd things. They might even try to herd you! They’re easy to train and obey their owners. They make good watchdogs too and they’ll let you know if someone’s at the door.
