What dog might wish to do to be lifted? (2,7)
I believe the answer is:
go walkies
'what dog might wish to do' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'be lifted?' is the wordplay.
'be' becomes 'go' (going is a kind of being).
'lifted?' becomes 'walkies' (I am not sure about this - if you are sure you should believe this answer much more).
'go'+'walkies'='GO WALKIES'
'to' is the link.
Can you help me to learn more?
(Other definitions for go walkies that I've seen before include "Disappear" , "Become missing" , "as may one man and his dog?" , "Appear stolen or lost?" , "Be missing (or stolen)" .)
