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.
Water dog Water dogs are a type of gun dog bred to flush and retrieve game from water, often serving the waterfowl hunter. Strong swimming desire is a characteristic of these dogs. Some of the oldest dog breeds are water dogs. The term was originally water spaniels (a misnomer, as not all are spaniels). With the advent of kennel clubs many "water spaniels" were accepted under the names including the designation retriever rather than spaniel.
