Small cervid (3,4)
I believe the answer is:
roe deer
'small cervid' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for roe deer that I've seen before include "Delicate creature" , "Small graceful woodland animal" , "Antlered woodland creature" , "Small hoofed animal from Eurasia" , "Common wild animal" .)
