Just the sort of dog for a German shepherd (6)
I believe the answer is:
police
'shepherd' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for police that I've seen before include "Law-and-order force" , "Emergency service" , "Long arm of the law" , "Limbs of the law" , "Boys in blue" .)
