Nova Scotia Duck Tolling Retriever
The Nova Scotia Duck Tolling Retriever (Toller) was developed in the early 19th century to toll, or lure, and retrieve waterfowl.  The playful action of the Toller retrieving a stick or ball along the shoreline arouses the curiosity of the ducks offshore.  They are lured within gunshot range, and the dog is sent out to retrieve the dead or wounded birds.
