Life threatening situation?

so far i haven't been to life threatening situations. and if ever i have been with that situation i don't know what would i react or feel. would i panicked? or could i go through it. could i? hopefully so. maybe i could handle it easily but just hoping it won't be that hard or too hard to handle too.

I think the biggest life threatening situation that I have been in was when I was eleven years old. This happened back in 1997. I was with my mother and a relative and we had gone to visit someone my relative was pretty good friends with at the time. She lived out in the country and she owned a Rottweiler. My mother and relative were afraid to get out to go knock on the door. So naturally I had to go knock on the door. I walked past the Rottweiler and it just sat there. I walked up to the front porch and the dog just sat there. I knocked on the door and the dog charged. The next thing I knew the dog was on me literally. It's front paws were on my shoulders and it was just about to sink its teeth into my neck when the owner came out and stopped it. If the owner had been a second later, the dog would have killed me. It shook me up pretty bad, I won't deny.
