Intrepid hound Aunt Edwina shows (9)
I believe the answer is:
undaunted
'intrepid' is the definition.
(I've seen this before)
'hound aunt edwina shows' is the wordplay.
'shows' indicates the answer is hidden within the clue.
'UNDAUNTED' is hidden in the letters of 'hound aunt edwina'.
(Other definitions for undaunted that I've seen before include "Intrepid" , "Not afraid or discouraged" , "Fearless" , "showing no fear" .)
