What is the difference between a Working Cocker Spaniel and a Field Spaniel?

Working Cocker Spaniels and Field Spaniels are both spaniel breeds, but there are distinct differences between the two in terms of their appearance, temperament, and purpose. 

Working Cocker Spaniels are highly energetic, smaller, and specifically bred for hunting with a focus on working ability and stamina. Field Spaniels are larger, with a calmer temperament more suited for families, and still retain hunting abilities but with a focus on being well-rounded companions.
