Crikey, Joe, what short legs it has! (5)

I believe the answer is:

corgi

I'm a little stuck... Click here to teach me more about this clue!

'short legs it has' is the definition.
I can't tell whether this definition defines the answer.

'crikey joe' is the wordplay.
'crikey' becomes 'cor' (both are expressions of surprise).
'joe' becomes 'GI' (GI Joe).
'cor'+'gi'='CORGI'

'what' acts as a link.

Can you help me to learn more?

(Other definitions for corgi that I've seen before include "Cardigan, possibly" , "Cardigan or Pembroke dog" , "Royal canine" , "man's best friend" , "HM's favourite dog" .)

I've seen this clue in the Evening Standard.
