This
is a short history of the Keeshond taken from "Belonging to a
Keeshond" by the late Barbara Glover. Hopefully in the future
we will have a longer, more detailed version. There is an excellent
site that covers the developement of the breed in the 20th century
illustrated with contemporary newspaper cuttings; follow the link
below.
Keeshonds form one of the canine families known as "Spitz".
The Spitz breeds originate from the Northern Hemisphere and are identified
by their wedge-shaped heads, prick ears, dense, off-standing coats
and tails carried over their backs.
In the middle of the eighteenth century mention was first made of
the large Pomeranian in England and a Spitz type dog is to be seen
in pictures from that time onwards; the forerunner of the Dutch Spitz,
or Keeshond, which became so popular in the 20th century.
In Germany and Holland these dogs were used to guard the barges that
plied up the Rhine. Keeshonds are essentially home or house dogs,
guards of their owners and their owners' belongings. Their extremely
sensitive hearing makes them invaluable to give warning of any sound
and there are many who have experienced this trait from the canal
sides in Holland. Dutch Barge Dogs, as they are often called for convenience
sake, have lost that job now the days of mechanisation are with us,
apart from a few exceptions.

For
the origin of Keeshond as a name there are many explanations, the
most popular being that when Holland was divided by two major political
parties, the leader of one, who was always accompanied by a group
of Spitz hounds, was a man called Cornelius. Kees being the nickname
for Cornelius, these dogs came to be known as Keeshonds. Kees is pronounced
Caze in Dutch, so we call our dogs 'Kayshonds'.
