 "Most Cur breeders were not well off and so they required a dog that could serve multiple purposes: hunter, guardian, and stock dog.

The East Siberian Laika (Vostotchno-Sibirskaia Laika) is a Russian breed of dog of spitz type, a hunting dog originating in parts of Siberia east of the Yenisei River.
The West Siberian Laika or "WSL", is a breed of hunting dog and a breed of spitz type.
 Russian publications indicate that the term West Siberian Laika loosely applied to hunting dogs originating with the Mansi and Khanty people in Ural and West Siberia, but there were no standards or registrations of WSL as such until 1930.
 Then WWll disrupted it for a while, but "systematic breeding with registrations" resumed after the war ended, in 1946.
 This was the time the breed began taking modern shape.
 Before that hunters only knew of Mansi Laika and Khanty Laika.
 In early 1960 many hunters in Ural still preferred the term Mansi Laika, when speaking of West Siberian Laika.
 In Russian language, the term Laika originated from the word "layat" that means to bark.
 The word Laika simply means "barker".
 Any hunting Laika is a bark pointer (pointing at animal of interest by barking and staying with the animal ).
 It is a versatile dog depending on use and environment, but in certain parts of the country they have become more specialized.

 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.
