paragraph_text: The English Springer Spaniel is a breed of gun dog in the Spaniel family traditionally used for flushing and retrieving game. It is an affectionate, excitable breed with a typical lifespan of twelve to fourteen years. They are very similar to the Welsh Springer Spaniel and are descended from the Norfolk or Shropshire Spaniels of the mid-19th century; the breed has diverged into separate show and working lines. The breed suffers from average health complaints. The show - bred version of the breed has been linked to ``rage syndrome '', although the disorder is very rare. It is closely related to the Welsh Springer Spaniel and very closely to the English Cocker Spaniel; less than a century ago, springers and cockers would come from the same litter. The smaller`` cockers'' hunted woodcock while the larger littermates were used to flush, or ``spring '', game. In 1902, The Kennel Club recognized the English Springer Spaniel as a distinct breed. They are used as sniffer dogs on a widespread basis. The term Springer comes from the historic hunting role, where the dog would flush (spring) birds into the air.
