Dog with hardly any time to come in? (6)
I believe the answer is:
curfew
'time to come in?' is the definition.
'dog with hardly any' is the wordplay.
'dog' becomes 'cur' (cur is a kind of dog).
'with' is a charade indicator (letters next to each other).
'hardly any' becomes 'few' ('few' can be similar in meaning to 'hardly any').
'cur'+'few'='CURFEW'
(Other definitions for curfew that I've seen before include "Hour to be home by" , "travel restriction" , "Restriction on going out" , "Regulation requiring people to be indoors during certain hours" , "Restriction on night-time movements" .)
