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.
Small Münsterländer The Small Münsterländer (also SM or Kleiner Münsterländer) is a versatile hunting-pointing-retrieving dog breed that reached its current form in the area around Münster, Germany. The Large Münsterländer is from the same area, but was developed from different breeding stock and is not related as the names would suggest. Small Münsterländers bear a resemblance to both spaniels and setters but are more versatile while hunting on land and water. The Small Münsterländer is recognized by the Fédération Cynologique Internationale under Group 7, Section 1.2, Continental Pointing Dogs of Spaniel type, by the American Kennel Club as a Foundation Breed, and by The Kennel Club and the United Kennel Club as a gun dog. It is related to the Epagneul Français and the Drentsche Patrijshond.
