Antelope’s two little twins pronking (3-3)

I believe the answer is:

dik-dik

'antelope's' is the definition.
(I've seen this before)

'two little twins pronking' is the wordplay.
'two little twins' becomes 'kid kid' (a pair of children).
'pronking' says the letters should be written backwards (in a down clue, letters jump or 'pronk' up).
'kidkid' reversed gives 'DIK-DIK'.

(Another definition for dik-dik that I've seen is " African antelope".)

I've seen this clue in The Guardian.
