Do both Landseer and Wetterhoun breeds go by different names?
Landseer (dog):  It is not to be confused with a white and black Newfoundland, which is also often called a "landseer". Wetterhoun:  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.
