In temperament it is cheerful and affectionate, and it is often called the merry cocker, a nod to its lively nature and busy tail. It is keen to please and closely attached to its people. Working-line dogs are generally more driven than show-line ones.
It is a compact, solid spaniel with a well-developed, cleanly chiselled head, a square muzzle and long, low-set ears. Its coat is silky and flat, with feathering on the legs, chest and underside. Colours include solid black, red and golden, as well as parti-colours and roans such as blue roan.
The English Cocker Spaniel took its modern form in Britain in the late nineteenth century, when breeders fixed its type around a few foundation dogs. Among them was a black dog named Obo, often called the father of the breed. In the twentieth century the Ware kennel of H. S. Lloyd did much to shape the breed, and its dogs won the top award at Crufts several times. Bred to push through dense cover, flushing game for the gun and then retrieving it, the breed remains a common working gundog and is also used as a detection dog.
