The Keeshond ( KAYSS-hond, plur. Keeshonden) is a medium-sized dog with a plush, two-layer coat of silver and black fur with a ruff and a curled tail. Their closest relatives are the German spitzes such as the Großspitz (Large Spitz), Mittelspitz (Medium Spitz), Kleinspitz (Miniature Spitz), Zwergspitz (Dwarf-Spitz) or Pomeranian. The Keeshond was previously known as the Dutch Barge Dog, as it was frequently seen on barges traveling the canals and rivers of the Netherlands.
