Porter has people paying to see Jack Russell? (10)
I believe the answer is:
gatekeeper
'porter' is the definition.
(I know that porter can be written as gatekeeper)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for gatekeeper that I've seen before include "Entrance attendant" , "Entry attendant; butterfly" , "man at wicket" .)
