Ouroboros Spine The trouble was...

As smart girl, his daughter did not bother wasting her time on something that could not be reached. She focused on her abilities and what was within her grasp. Aiolos found himself dancing, lifting his paws and dodging her bites as best he could.

 In the tight quarters of the den, he could not avoid her well. Tiny teeth bit all over his ankles until new teeth bit down onto his toes in just the wrong (or right) way. OW! He yelps, jerking his foot out from her mouth and shaking it wildly. Little devil! 

And so does he use the top of his skull to push against her and flop her to the ground.
