Terrier type named for a Scottish isle (4)
I believe the answer is:
skye
'terrier type named for a scottish isle' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for skye that I've seen before include "Scotland island" , "somewhere off Scotland's west coast" , "part of Scotland" , "Hebridean island close to mainland" , "Portree island" .)
