The big hunter gritted his teeth as the smaller frame of the man wolf betrayed its actual strength.  It was taking all his skill and strength to keep it in check.  Fighting an actual wolf or a human was much different that dealing with this creature.  If you held a wolf by the back and prevented them from turning around, then their main weapons, which is their jaws, were nullified.  Also, in this manner, you could prevent the harsh paw nails from tearing you up. 

If fighting a human, then you analyze the way they fight and discern the weakness to exploit it.  Arn had not been in many fights but he had been able to win because the prospect of injury is often a driving concern.  The only way humans overcame this fear was through intoxication.  Which then was another hinderance.

The creature however, was a challenge because it did not behave fully like a wolf.  Wrestling it to the ground and keeping it there while avoiding bites and getting clawed was difficult.  Despite not having teeth or claws as dangerous as an animal, the scratches he was suffering could turn deadly if infection set it. 

The man wolf was fighting with all its might.  There was not reasoning with him.  In the wild, the only reason bodies are this close is either mating or a fight to the death.  No doubt the creature thought it was the latter.  Arn came to a conclusion that was risky.  

Using a technique he had learned from a fur trader that had watched the big man get into a fight, he secure his own strong legs around the waist of the man wolf while mounted on him.  He the rolled so that his own back was to the ground and the creature was looking up at the sky.  Then, grasping the only thing he could, the very life like ears, he tugged backward.

The aim was to use his bigger frame to secure the man wolf and eventually slide his arm under the throat of the creature.  Applying enough pressure, hopefully would make the creature loose consciousness.  This would hopefully allow the young healer enough time to treat the wound and Arn enough time to secure the creature once it woke.
