Heavier than any other spaniel, the Clumber is a long, low dog with massive bone, a broad head, a heavy brow and soft, deep-set amber eyes. It takes its name from Clumber Park in Nottinghamshire, England, the Duke of Newcastle's estate, and it was among the first breeds the AKC recognized, in 1884. The dense, soft coat is mostly white with lemon or orange markings, which once helped hunters see the dog working through thick cover.
Many Clumbers are gentle, affectionate and easygoing at home, with a dignified, sometimes aloof manner toward strangers. Bred to flush and retrieve birds at a steady pace rather than a sprint, they usually have moderate energy and plenty of endurance. Adopters should be ready for shedding, drool, snoring and a strong food drive. The breed is uncommon, so finding one may take patience.
