Dogs have a long history of serving humans in various roles, including hunting, shepherding, and assisting law enforcement. In recent times, dogs have also become crucial in environmental conservation, serving as guardian and sniffer dogs. Guardian dogs protect vulnerable species from predators, while sniffer dogs have an incredible sense of smell, which helps them detect specific animals, plants, or byproducts. Any breed, sex, or age can be trained for this role as long as they exhibit the requisite behavior, highlighting the vast potential of our canine companions in the fight to preserve biodiversity.
