Story of dog read out (4)
I believe the answer is:
tale
'story' is the definition.
(I know that story can be written as tale)
'dog read out' is the wordplay.
'dog' becomes 'tail' (synonyms).
'read out' indicates a 'sounds like' (homophone) clue.
'tail' sounds like 'TALE'.
'of' is the link.
(Other definitions for tale that I've seen before include "See 12" , "Anecdotal narrative" , "An account of incidents or events" , "Report" , "Yarn or story" .)
