Bird dog (7)

Ross

I think it could be either:

harrier

griffon

I believe this clue is a double definition.

'bird' is the first definition.
(harrier is a kind of bird)

'dog' is the second definition.
(thesaurus)

(Other definitions for harrier that I've seen before include "Hare hound" , "that flies!" , "Bird - dog - plane" , "may get on your back?" , "jump jet" .)

I've seen this clue in The Globe and Mail and The Telegraph.
