Some of the best workers in America don’t get paid. But these employees aren’t quitting or even complaining. Why? They’re dogs! Professional pooches do a variety of tasks. Dogs can be “eyes” for the blind and “ears” for the deaf. And they sometimes bring joy to nursing home residents.

Dogs do many other jobs, too. That’s because they are doggone dependable! They pull sleds and help solve crimes. They inspect luggage for illegal drugs or food items. They hunt for missing persons. They even help with cattle herds.
