Cheers small canine, pointer according to Spooner (6-3)
I believe the answer is:
toodle-pip
'cheers' is the definition.
(I've seen this before)
'small canine pointer according to spooner' is the wordplay.
I cannot really understand how this works, but
'to' is present 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 toodle-pip that I've seen before include "Goodbye (dated)" , "Farewell remark - dipole top (anag)" , "Farewell (informal)" , "so long" , "Take care" .)
