The Curly-Coated Retriever's history is a bit unclear, but it is generally accepted that the breed originated in England in the late 1700's. They are believed to be the oldest of the Retriever breeds. Curly-Coated Retrievers are likely descendents of English Water Spaniels and Retrieving Setters, both of which are now extinct, as well as Irish Water Spaniels, St. John's Dogs, and Poodles. Curly-Coated Retrievers were used to hunt upland birds and waterfowl, with their thick, curly, waterproof coat protecting them from icy water and briers.
