Dog tag earned having gone through training (5,4)

Ross

I believe the answer is:

great dane

'dog' is the definition.
(Great Dane is an example)

'tag earned having gone through training' is the wordplay.
'having gone through training' indicates anagramming the letters (to train a plant is to manipulate its growth).
'tag'+'earned'='tagearned'
'tagearned' with letters rearranged gives 'GREAT DANE'.

(Other definitions for great dane that I've seen before include "Big dog" , "Hamlet possibly" , "Dog from Copenhagen?" , "A best friend" , "Pet" .)

I've seen this clue in The Independent.
