Do both Landseer and Wetterhoun breeds go by different names?
Wetterhoun The Wetterhoun (FCI No.221, translated into English as the Frisian Water Dog) is a breed of dog traditionally used as a hunting dog for hunting small mammals and waterfowl in the province of Fryslan in the Netherlands. The name of the dog comes from the West Frisian "Wetterhûn" meaning "water dog." Plural of Wetterhoun is Wetterhounen in Dutch. The breed may also be called the "Otterhoun" (not to be confused with the Otterhound) or "Dutch Spaniel", although it is not a Spaniel-type dog.
Kooikerhondje The Kooikerhondje (literal English translation "little cager dog" or "little caging dog") is a small spaniel-type breed of dog of Dutch ancestry that was originally used as a working dog, particularly in an "eendenkooi" (duck cage) to lure ducks. Kooikers were popular in the 17th and 18th century and appeared in the paintings of Rembrandt and Jan Steen. The breed is rapidly gaining popularity in the United States, Canada and Scandinavia, where it is still relatively unknown.
