Suffer at home with bad dog (5)
I believe the answer is:
incur
'suffer' is the definition.
(to incur is to suffer or experience)
'home with bad dog' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'with' is a charade indicator (letters next to each other).
'bad dog' becomes 'cur' (I've seen this in another clue).
'in'+'cur'='INCUR'
'at' is the link.
(Other definitions for incur that I've seen before include "contract" , "Runic (anag.)" , "To become liable to, suffer" , "Become liable to (eg, a penalty)" , "Arouse" .)
