Hand over whelp and dogs, lacking time on return (5,2)
I believe the answer is:
stump up
'hand over' is the definition.
(both can mean to provide or give)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for stump up that I've seen before include "Pay (the money required) (colloq.)" , "Arrive on wooden leg" , "is what an umpire draws, at the end of the day" , "Pay a sum of money (colloq.)" , "Pay one's dues" .)
