A job for a dog needs to engage both brain and body. How does a dog think? We can’t entirely know the answer to that, but we know dogs have instincts that would help them survive in the wild. They also have drives that have been shaped by selective breeding to enhance talents that humans have desired. These include herding livestock, retrieving, indicating game in the field, searching by scent, chasing by sight, and other pursuits. Different terms are used for these behaviors, but basically they are “hard-wired” in the brain.
