Dog fouled street (6)
I believe the answer is:
setter
'dog' is the definition.
(setter is a kind of dog)
'fouled street' is the wordplay.
'fouled' indicates anagramming the letters.
'street' anagrammed gives 'SETTER'.
(Other definitions for setter that I've seen before include "who is giving you problems right now?" , "Mike of this parish, say" , "puzzle constructor" , "Thematic type [DOG]" , "pointer" .)
