Perfect cherry drink for dog (8)
I believe the answer is:
airedale
'dog' is the definition.
(Airedale is an example)
'perfect cherry drink' is the wordplay.
'perfect' becomes 'ai' (I've seen this in other clues).
'cherry' becomes 'red' ('red' can be a synonym of 'cherry').
'drink' becomes 'ale' (ale is a kind of drink).
'ai'+'red'+'ale'='AIREDALE'
'for' is the link.
(Other definitions for airedale that I've seen before include "Mutt" , "best friend?" , "Yorkshire district; breed of terrier" , "Canine breed" , "A leader I turn into a large breed of dog" .)
