Clumber Park, near Worksop in Nottinghamshire, was created as a deer park in 1709 but the first hall was built by Henry Fiennes Pelham-Clinton, the 2nd Duke of Newcastle-under-Lyme, in the 1760s.
Rob Holder, general manager at Clumber Park, said while the origins of the Clumber spaniel were not clear, they may have come from a kennel of prized spaniels gifted to the 2nd Duke.
“It was the Duke and his gamekeeper that then worked with the spaniel to create the breed we know today,” he added.
“They were designed to be a gundog, a hunting dog, that would work the heathland of Sherwood Forest.
“There is not a day goes by that you don’t see a Clumber spaniel in the park, but it is not as well known as some breeds.
“We are very proud of our heritage and of the fact there is a dog that was bred here and named after the park – it’s amazing it has gone on to win Crufts.”
