One of my German Shepherds was always doing stupid shit like this.
Once he had a Scorpion in his mouth he was chewing on. Scorpion got a sting in and he was frothing but he made it ok.
Then he chewed the head off a Rattlesnake. Nothing happened to him, but the snake was a goner.
But the worst he chased a Skunk. Skunk got away but my dog got scent bombed up close and smelled like shit for days. I washed him over and over and couldn't get rid of the stink. Finally I found out you have to wash them with tomato juice to counteract the stink and that did the trick.
