Wild dog in pound in Goole (5)
I believe the answer is:
dingo
'wild dog' is the definition.
(dingo is a kind of wild dog)
'in pound in goole' is the wordplay.
'in' indicates a hidden word.
'DINGO' is hidden within 'pound in goole'.
(Other definitions for dingo that I've seen before include "Wild creature" , "Want a dog" , "Aussie wild dog" , "Kipling's "Yellow-Dog"" , "Wild Australian dog" .)
