Does and stags (4)
I believe the answer is:
deer
'does and stags' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for deer that I've seen before include "does for example" , "Ruminant(s) -- breed of 13 down" , "The males have antlers" , "Wild animal" , "The male has antlers" .)
