Step-by-step explanation:
Dogs are more commonly associated with herding and guarding than guards are. Dogs were key to the development of pastoralism, where they were utilized as shepherds to protect and guide domesticated herds. Dogs have a natural instinct to protect, making them fierce defenders of their herd or family. They are also used in a wide range of human activities, such as drug detection, therapy animals, and guides for those with physical challenges.
