Famous Scandinavian dog (5,4)
I believe the answer is:
great dane
'dog' is the definition.
(I know that Great Dane is a type of dog)
'famous scandinavian' is the wordplay.
'famous' becomes 'great' (I've seen this in another clue).
'scandinavian' becomes 'dane' (person from Denmark).
'great'+'dane'='GREAT DANE'
(Other definitions for great dane that I've seen before include "hound" , "Large breed of dog" , "Big dog" , "Dog -- a tad green (anag)" , "Pet" .)
