Although he may look serious, the Clumber Spaniel is actually a sweet and playful dog. He's relentless and determined in the field and a loving playmate at home. These are medium-sized, but heavy-boned dogs, eager to please and amiable. Like many sporting dogs, the breed is very trainable despite having a bit of an independent mind. They respond best to positive training. They do shed and they're known to be droolers, but your Clumber Spaniel puppy can also be the family's BFF -- he's a patient friend to kids and an affectionate and amusing companion.
