I discovered that you can manipulate the AI on the wolves. They are way less aggressive if you aren't looking at them in your camera angle. Turn Chris around to face the wall and you should only get bit 3 to 4 times. Decoys make it even easier.
A weird glitch happened to me on my first try. I wish I recorded it so I could have proof but I don't have 3DS capture. I died on my first attempt of this (without knowing the Wolf strategy). The thing is, though, I didn't 'actually' die. Chris did his death scream but as the screen was fading I suddenly revived. I was able to make it through to the end point until my game soft-locked. The gate was shut behind me, the cutscene didn't trigger, and I couldn't even pause my game to restart the chapter.
It was a strange experience. I have almost 50 hours of gametime split between Campaign and Raid mode, but this is the first time that I encountered a glitch in the game.
