Devon terrier with leg cocked - classic dog! (6,9)
I believe the answer is:
golden retriever
'dog' is the definition.
(golden retriever is a kind of dog)
'devon terrier with leg cocked classic' is the wordplay.
I cannot really see how this works, but
'classic' could be 'old' and 'old' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for golden retriever that I've seen before include "Dog" , "canine" , "pet?" .)
