Golden Retrievers were "developed" in Britain during the 1800's. Believed to be included in the formation of the Golden Retriever breed are the now extinct Tweed Water Spaniel, the Newfoundland, the Irish Setter and a variety of water spaniels. Lord Tweedmouth takes credit for the development of the Golden Retriever. On his estate, near Inverness, Scotland, Lord Tweedmouth wished to develop a dog which was loyal and kind, yet spirited and energetic, with a love for the water and an ability to retrieve. His early vision of a Golden Retriever was for a dog that would have great enthusiasm for retrieving waterfowl. Early golden retrievers ranged from medium gold to dark gold to a "copper" gold. As the golden retriever developed and became more popular in the show ring, the lighter colours, seen in today's Golden Retrievers, emerged. Today Golden Retrievers range from cream to dark gold with the lighter colours seemingly more preferred by many than the darker colours of the original Golden Retrievers. I just hope this helps.
