Trip with former partner and dog having commotion (almost) on the way back (9)
I believe the answer is:
excursion
'trip' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for excursion that I've seen before include "Journey taken for pleasure" , "Pleasure outing" , "Jaunt" , "Day-trip" , "Outing, junket" .)
