In temperament it is loyal and affectionate, closely attached to its own people and sometimes reserved with strangers. It is an energetic, persistent worker that tends to stay near its handler in the field.
It is compact and sturdy, slightly longer than it is tall, and a little smaller and lighter in build than the English Springer Spaniel. The coat is straight, flat and silky, a rich red in patches or flecks on white, with moderate feathering on the chest, legs and ears. Its ears are comparatively small and are often likened to the shape of a vine leaf.
The Welsh Springer Spaniel took its modern form in the late nineteenth century, when sporting families in South Wales, particularly around Neath, began breeding the local red and white spaniels to a consistent type and showing them. The breed reached the United States early in the twentieth century. Numbers fell sharply during the Second World War, and the breed was rebuilt afterwards from relatively few dogs. It was bred to work through hedgerows and dense cover, flush game birds into the air for the gun and retrieve them, and it is valued for its stamina on rough ground and in wet weather.
