CLUMBER SPANIEL. The Clumber Spaniel’s long and low build is particularly unique among spaniels. Although not as speedy as other sporting dogs, the Clumber will work all day, trotting along in his signature slow, rolling gait. He may appear dignified and pensive, but he possesses great enthusiasm for both work and play. The breed possesses a beautiful white coat and may have lemon or orange-colored markings. The Clumber is believed to be one of the earliest spaniels developed for special uses and is especially useful for his adaptability for use in heavy cover; he generally hunts mute and is able to come up very close to the game.
