Fox's Glade like lawyers in a murder case

Take my 100th :)
(and gg if this is it!!)

     The fight had been long and arduous; with both wolves pulling hard from their will and sacrificing much in the way of blood and sweat. His own breaths, which before were so calmly executed and preserved, now spilled from his lips with every great heave of his mangled flanks. 

     His strength was ebbing quickly, he realized. His hold, while still deep into the sinewous fibers of his opponent's leg, was slipping with every fresh wave of pain. Cursing, he prodded his forepaws deep into the earth and pushed himself backward; releasing his clamped jaws with at least the comfort of alleviated tension. 

     The large wolf looked strange in his flight: his body rolled backward in a half-twist as he caught himself. Indeed, he was vulnerable to what could possibly become the final straw in this myriad of onerous events.
