Stroke pet — racket follows (5-6)
I believe the answer is:
doggy-paddle
'stroke pet racket follows' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'stroke pet racket follows' is the wordplay.
'stroke pet' becomes 'doggy' (I can't explain this - if you can you should believe this answer much more).
'racket' becomes 'paddle' (paddle is a kind of racket).
'follows' says to put letters next to each other.
'doggy'+'paddle'='DOGGY-PADDLE'
Can you help me to learn more?
(Other definitions for doggy-paddle that I've seen before include "Simple swimming stroke" , "Elementary swimming stroke" .)
