Short-legged breed of dog (5)
I believe the answer is:
corgi
'short-legged breed of dog' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for corgi that I've seen before include "Royal pet" , "found in the kennels" , "Welsh breed of short-legged dog" , "Toy car manufacturer" , "Pre-2018 royal dog" .)
