In the Nosework class today, Eusébio finds the cardboard box or the container with the scent. From Wikipedia: “Nosework, also known as scent work or scent detection, is a dog sport created to emulate tasks performed by professional detection dog. In the sport, one dog and one handler form a team where the dog must find a hidden target odor, often ignoring distractions such as food or toys, and alert the handler once the target odor is found.”
