Young dogs grabbing male's plimsolls (5)
I believe the answer is:
pumps
'plimsolls' is the definition.
(I've seen this before)
'young dogs grabbing male's' is the wordplay.
'young dogs' becomes 'pups' (puppies).
'grabbing' indicates putting letters inside.
'male' becomes 'm' (common abbreviation).
'pups' going around 'm' is 'PUMPS'.
(Other definitions for pumps that I've seen before include "Water-raising devices" , "needed by cyclists" , "Dancing shoes - may be manned!" , "leading questions" , "footwear" .)
