A few years later, this idea was challenged by Rudolf Schenkel, who suggests that, contrary to Lorenz’s beliefs, the inferior dog is the one with his jaws open near to the superior’s neck. The superior canine remains growling and his posture is erect, as though to prepare for an attack. Schenkel suggests that the bite inhibition in this instance is shown by the inferior to show that he does not dare to bite the superior.[9]
