Long walks dogs may go for? (6)
I believe the answer is:
tramps
'long walks' is the definition.
'tramps' can be an answer for 'walks' (tramp is a kind of walk). I am not sure about the 'long' bit.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for tramps that I've seen before include "Walks with heavy footfall" , "Hiking vagrants" , "Stumps" , "Journeys wearily" , "Walks heavily like hobos" .)
