The sheep were scattered in the field to roam around and breathe. They are taking this moment as their freedom because they will be gathered again after several minutes. They will be gathered with the help of the herding dog. This dog is trained and an expert in herding. It is only one herding dog, but it can manage lots of sheep in the field.
