I'd be interested in the story behind that, that's just crazy. I've had dogs get hit before and they act like they're dying with only 2 or 3 quills, I'd honestly be surprised if that dog kept its left eye.
Man, words simply fail to describe how bad that has to hurt. I simply can't image what would have driven that dog to endure that much pain, because that has to be from multiple hits. That's just gotta hurt.
