Do Clumber Spaniels bark a lot?

No, Clumber Spaniels do not bark a lot. In fact, they are one of the quieter breeds. However, a Clumber might bark when they are excited or if someone approaches their territory. As with any dog, early socialization and training can help shape their behavior, including barking tendencies. Providing them with enough mental and physical stimulation can also help reduce unnecessary barking.
