Tony's blurb rewritten doggedly (10)

I believe the answer is:

stubbornly

'doggedly' is the definition.
(thesaurus)

'tony's blurb rewritten' is the wordplay.
'rewritten' is an anagram indicator.
'tonys'+'blurb'='tonysblurb'
'tonysblurb' with letters rearranged gives 'STUBBORNLY'.

I've seen this clue in the Sydney Morning Herald.
