Dog left out in the open given drink at the pub (8)
I believe the answer is:
airedale
'dog' is the definition.
(Airedale is an example)
'left out in the open given drink at the pub' is the wordplay.
'left out in the open' becomes 'aired' (left in the open air).
'given' says to put letters next to each other.
'drink at the pub' becomes 'ale' (alcoholic drink).
'aired'+'ale'='AIREDALE'
(Other definitions for airedale that I've seen before include "Yorkshire valley" , "Yorkshire district; breed of terrier" , "Mutt" , "Barker" , "Terrier - Yorkshire area" .)
