Chinese lap dog, for short (4)
I believe the answer is:
peke
'chinese lap dog for short' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for peke that I've seen before include "Breed of dog (shortened)" , "Small breed of dog" , "Snub-nosed lap-dog (colloq.)" , "Small snub-nosed dog" , "5 [MANS BEST FRIEND]" .)
