If you want dog.voice() to just print "voice: bark", you just have to omit
the voice method for the dog class: it will be inherited from creature.

If you want dog.voice() to do something else, you can call superclass'
method like this:

    def voice(self):
        creature.voice(self)
        print "brace your self"
        any_other_magic()
