Badgers or hounds (4)
I believe the answer is:
nags
I believe this is a double definition.
'badgers' is the first definition.
(I've seen this in another clue)
'hounds' is the second definition.
(I've seen this in another clue)
(Other definitions for nags that I've seen before include "Pesters" , "Worries; horses" , "Annoys" , "Constantly reproaches and complains" , "Scolds constantly" .)
