It’s unknown as to how the Clumber Spaniel came to existence but according to today’s predominant point of view it was bred by sportsmen and gamekeepers in the second half of the XVIII century. The breed’s name is derived from the Duke of Newcastle’s estate at Clumber Park in Nottinghamshire, England. To a large degree it owes its appearance to the breeding efforts of the Duke’s gamekeeper, William Mansell. It’s speculated that this avid hunter primarily used Bleinheim Spaniels in his breeding program. However it’s also highly probable that the Alpine Spaniel, the Bloodhound, or even the St. Bernard were actively involved in its development.
