Lackey — curly-haired dog (6)
I believe the answer is:
poodle
This clue is a double definition.
'lackey' is the first definition.
(I've seen this before)
'curly-haired dog' is the second definition.
(I've seen this in another clue)
(Other definitions for poodle that I've seen before include "toady?" , "Curly-haired breed of dog" , "Dog (seen in a parlour?)" , "Pet dog; obsequious chap" , "Pet dog with clipped curly coat" .)
