Goes out with hounds in county as before (5)
I believe the answer is:
hunts
I believe this clue is a double definition.
'goes out with hounds' is the first definition.
'county as before' is the second definition.
(abbreviation for Huntingdonshire, historic county)
'in' acts as a link.
(Other definitions for hunts that I've seen before include "country pursuits" , "Traditional county" , "Chases and kills (prey)" , "Pursues wild animals for sport" .)
