Floppy, limp (6)
I believe the answer is:
droopy
I believe this clue is a double definition.
'floppy' is the first definition.
(thesaurus)
'limp' is the second definition.
(I've seen this before)
(Other definitions for droopy that I've seen before include "Lacking strength" , "Cartoon poodle" , "Pessimistic, long-eared cartoon dog" , "Cartoon dog - sagging" , "Hanging limply - animated dog created by Tex Avery" .)
