Keeshond

Dog

The Keeshond is a medium-sized dog with a plush two-layer coat of silver and black fur with a 'ruff' and a curled tail. It originated in Germany, and its closest relatives are the other German spitzes such as the Pomeranian. Originally called the German Spitz, more specifically the Wolfsspitz, the name was officially changed to Keeshond, in 1926 in England, where it had been known as the Dutch Barge Dog.
