Trained gudong, one working with hunters (3,3)

I believe the answer is:

gun dog

'one working with hunters' is the definition.

'trained gudong' is the wordplay.
'trained' is an anagram indicator (to train can mean to grow something into a shape).
'gudong' anagrammed gives 'GUN-DOG'.

(Other definitions for gun dog that I've seen before include "21a 24 [GAMEKEEPER] 's hound" , "Eg, retriever" , "eg Pointer" , "'Canine for a shooter (3,3)'" , "Canine trained to retrieve game" .)

I've seen this clue in The Everyman puzzle in The Observer.
