Dog angered at being put out (5,4)
I believe the answer is:
great dane
'dog' is the definition.
(I know that Great Dane is a type of dog)
'angered at being put out' is the wordplay.
'being put out' is an anagram indicator.
'angered'+'at'='angeredat'
'angeredat' is an anagram of 'GREAT DANE'.
(Other definitions for great dane that I've seen before include "Powerful dog" , "Large 11" , "Hamlet possibly" , "Kierkegaard, perhaps?" , "Andersen" .)
