Short-legged dog breed (5)
I believe the answer is:
corgi
'short-legged dog breed' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for corgi that I've seen before include "Welsh breed of short-legged dog" , "The Queen's favourite?" , "HM's favourite dog" , "Small Welsh dog with fox-like head" , "Barker?" .)
