Stuff dog? Remains getting scattered (10)
I believe the answer is:
gormandise
'stuff' is the definition.
(I know that stuff can be written as gormandise)
'dog? remains getting scattered' is the wordplay.
'getting scattered' indicates an anagram.
'dog'+'remains'='dogremains'
'dogremains' anagrammed gives 'GORMANDISE'.
(Other definitions for gormandise that I've seen before include "gorge" , "scoff like a 28 [PIG] ?" .)
