Retriever breed (8)
I believe the answer is:
labrador
'retriever breed' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for labrador that I've seen before include "Breed of 1 across" , "Spaniard who works" , "Coastal region of eastern Canada" , "One that may have gone out with the guns" , "Region of NE Canada, or a retriever dog" .)
