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.
American Cocker Spaniel The American Cocker Spaniel is a breed of sporting dog. It is a spaniel type dog that is closely related to the English Cocker Spaniel; the two breeds diverged during the 20th century due to differing breed standards in America and the UK. In the United States, the breed is usually called the Cocker Spaniel, while elsewhere in the world, it is called the American Cocker Spaniel in order to differentiate between it and its English cousin, which was already known as "Cocker Spaniel" before the American variety was created. The word "cocker" is commonly held to stem from their use to hunt woodcock in England, while "spaniel" is thought to be derived from the type's origins in Spain.
