Golden horse (8)
I believe the answer is:
palomino
'golden horse' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for palomino that I've seen before include "colt?" , "Equine" , "Golden horse with pale mane" , "Golden horse with white mane and tail" , "White-maned horse of the southwest USA" .)
