Jules maybe stops pet rolling over as commanded (8)
I believe the answer is:
governed
'commanded' is the definition.
(governing is a kind of commanding)
'jules maybe stops pet rolling over' is the wordplay.
'jules maybe' becomes 'verne' (I can't explain this - if you can you should believe this answer much more).
'stops' means one lot of letters goes inside another (stopping can mean blocking a gap).
'pet' becomes 'dog'.
'rolling over' says the letters should be written in reverse.
'dog' written backwards gives 'god'.
'verne' going inside 'god' is 'GOVERNED'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for governed that I've seen before include "Ruled" , "kept under control" , "Exercised authority over" .)
