Europeans with great dogs (5)
I believe the answer is:
danes
I believe this is a double definition.
'europeans' is the first definition.
(Danish people)
'great dogs' is the second definition.
(I've seen this in another clue)
'with' is the link.
(Other definitions for danes that I've seen before include "E.g. Hamlet and Canute" , "Scandinavians" , "people in Copenhagen" , "Europeans who inhabit Andes" , "Vikings" .)
