Question: Which dog breed has more derivative breeds from the original, German Spitz or Norfolk Spaniel?

The Welsh Springer Spaniel is a breed of dog and a member of the spaniel family.  Thought to be comparable to the old Land Spaniel, they are similar to the English Springer Spaniel and historically have been referred to as both the Welsh Spaniel and the Welsh Cocker Spaniel.  They were relatively unknown until a succession of victories in dog trials by the breed increased its popularity.  Following recognition by The Kennel Club in 1902, the breed gained the modern name of Welsh Springer Spaniel.  The breed's coat only comes in a single colour combination of white with red markings, usually in a piebald pattern.  Loyal and affectionate, they can become very attached to family members and are wary of strangers.  Health conditions are limited to those common among many breeds of dog, although they are affected more than average by hip dysplasia and some eye conditions.  They are a working dog, bred for hunting, and while not as rare as some varieties of spaniel, they are rarer than the more widely known English Springer Spaniel with which they are sometimes confused. <SEP> The Norfolk Spaniel or Shropshire Spaniel is an extinct breed of dog since the early 20th century.  The term was used to designate springer type spaniels that were neither Sussex nor Clumber Spaniels, and attempts were made to use it to specify a breed that would later become known as the English Springer Spaniel.  It was originally thought to have originated from the work of one of the Dukes of Norfolk, but this theory was disproven after being in doubt during the later part of the 19th century. <SEP> German Spitz is used to refer to both a breed of dog and category or type of dog.  Several modern breeds have been developed from the German Spitz, and are either registered as separate breeds or as varieties of German Spitz.  All the "German Spitz type" dogs are dogs of the Spitz type of German origin.  The Großspitz, Mittelspitz, and Kleinspitz breeds of "German Spitz type" are also called the German Spitz in English. <SEP> 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.
