Jack is a 6-month-old sheep — but don’t tell him that! Just after he was born, he wandered inside his farm’s house and befriended the family dog. Since then, he and the dog have been inseparable, and Jack has even taken on canine habits. He plays fetch, goes for walks on a leash and even tries to bark. When Jack is put with the rest of the flock, he doesn’t try to join his fellow sheep. Rather, he tries to herd the sheep just like his dog companion does.
