A little diamond in gold canine (5)

I believe the answer is:

dingo

'canine' is the definition.
(dingo is a kind of canine)

'a little diamond in gold' is the wordplay.
'a little' indicates the answer is hidden within the clue.
'DINGO' is hidden within 'diamond in gold'.

(Other definitions for dingo that I've seen before include "Wild Australian dog" , "Wild animal" , "Australian native" , "Wild creature" , "Aus. wild dog" .)

I've seen this clue in The Telegraph.
