Tollers are named for their ability to entice or lure waterfowl within gunshot range, called 'tolling'. The hunter stays hidden in a blind and sends the dog out to romp and play near the water, usually by tossing a ball or stick to be retrieved. The dog's appearance is similar to that of a fox. Its unusual activity and white markings pique the curiosity of ducks and geese which swim over to investigate.
