Charon would try to grab his teeth round his daughter's snout, releasing again if he managed, or try to get just part of it such as her lower jaw so that she couldn't move — but never for long, and never to inflict any pain. He jumped up again during the spar and tried to wrap front paws round her, hoping that she would join.
