CHESAPEAKE BAY RETRIEVER. Developed along the Chesapeake Bay and named the state dog of Maryland, the Chesapeake Bay Retriever is a truly American sporting breed and the toughest water retriever. In 1807, an English brig shipwrecked off the coast of Maryland and two Newfoundlands were rescued from the cargo. When bred to local retrievers, including the English Otter Hound, Flat-Coat and Curly-Coated Retriever, the "Chessie" type developed. Bred to work on land and water, the Chesapeake Bay Retriever originally hunted waterfowl in rough and icy waters, often retrieving several hundred birds per day.
