Working like a dog: sheepherders, detectives, household helpers, and more

"Professional pooches do a variety of jobs. Dogs serve as "eyes" for the blind and "ears" for the deaf. And they bring joy to nursing home residents. Dogs do many other jobs too. They pull sleds, find crime clues, inspect luggage for illegal drugs or food items, hunt for missing persons, and much more. With the right training, dogs make great employees. They're smart, skilled, and loving. They're also doggone dependable."
