Bark’s texture (4)
I believe the answer is:
woof
I believe this clue is a double definition.
'bark's' is the first definition.
(I've seen this before)
'texture' is the second definition.
(thesaurus)
(Other definitions for woof that I've seen before include "Sound of dog's bark" , "Barking noise" , "boxer's outburst" , "Sound of bark - weft" , "Dog's noise" .)
