Read agent shot dog (5,4)
I believe the answer is:
great dane
'dog' is the definition.
(Great Dane is an example)
'read agent shot' is the wordplay.
'shot' is an anagram indicator.
'read'+'agent'='readagent'
'readagent' is an anagram of 'GREAT DANE'.
(Other definitions for great dane that I've seen before include "Could be barking" , "Large breed of dog" , "Hamlet possibly" , "one among best friends" , "Dog from Copenhagen?" .)
