Recent history has the breed taking its present form in the 1830s. Its development is credited to Justin McCarthy and his "Boatswain" dog. The breed's purpose is that of a waterfowl hunter; his strong swimming ability enables him to be physically qualified for the task. He is a quality retriever in any cover and is used for a variety of games.
