Dog talked about drink (8)
I believe the answer is:
airedale
'dog' is the definition.
(Airedale is an example)
'talked about drink' is the wordplay.
'talked about' becomes 'aired' (I am not sure about this - if you are sure you should believe this answer much more).
'drink' becomes 'ale' (type of beer).
'aired'+'ale'='AIREDALE'
Can you help me to learn more?
(Other definitions for airedale that I've seen before include "Thematic type [DOG]" , "Mutt" , "River valley; rough-coated terrier" , "part of Yorkshire" , "Canine breed" .)
