To his credit, the wolf was actually trying to finish it, and Craw could respect that.
It wasn't that they could have shared it Such altruism to strangers and competitors in life had been drilled out of him by his father, and if he waited his turn, who was to say that some meaner scavenger would not decide to skip the line? It had made sense to fight for his right to the quickest access to the meat. When it was clear that the combat was increasingly one sided, Craw had to make a change.
Deliberately slowing his last attack, Craw made sure to give the impression of dulled reactions and movement, seeing how effortlessly his rival avoided the attempt. Then the heist was revealed; when the smaller wolf came at Craw again, teeth all clumsy and thirsty for blood, the starving wolf expended a burst of energy left in the very bottom of his reserve to move away. He took a dark pleasure in the minute victory, seeing the clear surprise in his rival's movements, and used his momentum to open his jaws and snag his lower canines into the other's right thigh, the movement of both of them leaving a long, jagged and ugly gash up to his rump.
Now his blood was not the only one spilled. Chest heaving with exhaustion, blood trickling down his shoulders and sides, and with no other surprises in store, Craw simply turned himself to face his rival's inevitable retaliation, ready. He spat out the blood in his mouth, then bared his teeth again, the invitation clear. Let no-one say he worked in half-measures.
