Duck Tollers are working animals and are happiest when they have a job to do. Tollers are excellent hunting companions. They excel at many types of sporting competitions such as agility, dock diving, and obedience. Their keen sense of smell, intelligence, drive for work, and small size make them perfect search and rescue dogs. The breed standard states that the dog should have a strong retrieving drive, intense birdiness, endurance, and a love for water.
