Where did the Clumber Spaniel originate?
The Clumber Spaniel originated in England. The breed is believed to have been developed in the late 18th century, with significant contributions from the Duke of Newcastle’s estate, Clumber Park in Nottinghamshire. The breed’s exact origins are somewhat obscure, but the Clumber Spaniel might have descended from a combination of European spaniels and other sporting dogs brought to England.
