Which sporting breed was not developed in North America

Chesapeake Bay Retriever
Nova Scotia Duck Tolling Retriever

Ok I am not to sure about this one becase I have been told that the Yarmouth County, Nova Scotia, Canada, is considered the place of origin for the Nova Scotia Duck Tolling Retriever
and that the Golden Retriever origin was G. B.
