Quick round by a thirsty dog? (3,6)
I believe the answer is:
lap record
'a thirsty dog?' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'quick round by' is the wordplay.
'quick' becomes 'record' (I can't explain this - if you can you should believe this answer much more).
'round' becomes 'lap' (as in a round or lap of a park).
'by' is a charade indicator (letters next to each other).
'record' put after 'lap' is 'LAP RECORD'.
Can you help me to learn more?
(Another definition for lap record that I've seen is " Best all-round performance".)
