Context paragraphs:
West Siberian Laika: 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.

Welsh Springer Spaniel: The Welsh Springer Spaniel is a breed of dog and a member of the spaniel family.  Thought to be comparable to the old Land Spaniel, they are similar to the English Springer Spaniel and historically have been referred to as both the Welsh Spaniel and the Welsh Cocker Spaniel.  They were relatively unknown until a succession of victories in dog trials by the breed increased its popularity.  Following recognition by The Kennel Club in 1902, the breed gained the modern name of Welsh Springer Spaniel.  The breed's coat only comes in a single colour combination of white with red markings, usually in a piebald pattern.  Loyal and affectionate, they can become very attached to family members and are wary of strangers.  Health conditions are limited to those common among many breeds of dog, although they are affected more than average by hip dysplasia and some eye conditions.  They are a working dog, bred for hunting, and while not as rare as some varieties of spaniel, they are rarer than the more widely known English Springer Spaniel with which they are sometimes confused.
