how does cherokee defeat white fang?

WF can't get ahold of muzzle of other dog.

Cherokee was also so low top the ground. Then,

"The bulldog had managed to roll him over on his back, and still hanging on to his throat, was on top of him. Like a cat, White Fang bowed his hind-quarters in, and, with the feet digging into his enemy's abdomen above him, he began to claw with long, tearing strokes. Cherokee might well have been disembowelled had he not quickly pivoted on his grip and got his body off of White Fang's and at right angles to it."
