Smaller than the English
springer spaniel, the cocker spaniel is a dog bred especially for hunting along
hedgerows and thick cover. It faces this cover without hesitation and, in a
country such as Ireland with its many areas of natural cover still existing, the
breed is enjoying something of a revival in that country.
The name ‘cocker’ is derived from the quarry the
dog was primarily bred for hunting, the woodcock. 
It is widely held that the Blenheim spaniel
was bred from the cocker spaniel and that the cocker spaniel, in turn, was bred
from the King Charles spaniel.
It is not surprising that the cocker was one of
Ireland’s most popular gundog breeds at the turn of the 20th century when large
country estates dotted the Irish landscape. Doubtless the breed has suffered
from the attentions of the show fraternity but it is starting to make something
of a comeback both in Ireland and Scotland.
