Bird or dog similar to pig (8)

I believe the answer is:

curassow

'bird' is the definition.
(I know that curassow is a type of gallinacean)

'dog similar to pig' is the wordplay.
'dog' becomes 'cur' (both can mean a despicable person).
'similar to' becomes 'as'.
'pig' becomes 'sow' (I've seen this before).
'cur'+'as'+'sow'='CURASSOW'

'or' is the link.

(Another definition for curassow that I've seen is " Game bird".)

I've seen this clue in The Sunday Times.
