Drop litter with domestic servant (5)

Ross

I believe the answer is:

whelp

'drop litter' is the definition.
(to whelp is to give birth to a litter)

'with domestic servant' is the wordplay.
'with' becomes 'w' (abbreviation).
'domestic servant' becomes 'help' ('the help' can mean servants).
'w'+'help'='WHELP'

(Other definitions for whelp that I've seen before include "Cur" , "Puppy, cub" , "Young pup" , "Give birth to (a puppy)" , "Produce issue" .)

I've seen this clue in The Times.
