Greedy gobbler outside party an Asian stray (2-3)

I believe the answer is:

pi-dog

'an asian stray' is the definition.
(term for a stray dog in Asia)

'greedy gobbler outside party' is the wordplay.
'greedy gobbler' becomes 'pig' (someone who gobbles food greedily).
'outside' means one lot of letters goes inside another.
'party' becomes 'do' (do is a kind of party).
'pig' enclosing 'do' is 'PI-DOG'.

(Another definition for pi-dog that I've seen is " Ownerless cur in India".)

I've seen this clue in The Independent.
