The wetterhoun is a very typical European water dog. It looks very similar to the now extinct english water dog, but most likely originates from Friesland, the Netherlands, and is believed to be related to the Irish Water Spaniel as well as the Curly Coated Retriever. It is known for being extremely stubborn, and is an excellent watchdog. It was previously kept as an otter hunter, but today it serves as a bird dog.

The Wetterhoun was recognized by the Dutch Kennel Club, Rad van Beheer, in the 1942 with only twenty dogs registered in total. The breed very rare in the rest of the world and uncommon in Holland, but a Wetterhoun was exported to Sweden in the 1950's.

The stop is slight, with the muzzle shaped powerful and rounded. The ears are of medium size, spoon-shaped and set low. The coat on them is a breed trademark; wavy, rather long and shorter at the tips. The neck is short, round and powerful, carrying the head low.
