Hi folks. I mostly just lurk around here trying to learn things but thought I would share my experience that helped me make the decision to carry. Sorry for the long reply. Cliff notes version is that I was almost mauled by two huge dogs and it helped me make the decision to carry.
Back in the spring my family was visiting my parents. We arrive and are heading for the front door (wife/9 year old boy/7 year old girl) when a huge Rottweiler (easily 100 pounds) comes around the corner of dad's house barking, growling, showing teeth and being all around very aggressive. I recognize the dog as being owned by the guy that lives three houses down from my dad. Not a good sort of person, seems like every neighborhood has one. I also know he has another of these dogs.
So I put my skinny butt between the menacing dog and the family and tell them to get inside quick as they can. While they are moving toward the house the other huge Rottweiler comes around the corner of the house. At this point I reach back and pull out my Gerber pocket tool

() and flip open the 3 inch blade and pray that they don't come after me while slowly backing away. The dogs were probably 20 feet away at this point and stalking forward.
Thankfully we all manage to get inside unharmed. The dogs run back toward their house. At this point I'm pretty shaken and pissed. Mom is already on the phone to the police to report the dogs.
Two or three minutes go by and I'm still watching out the front door both for the dogs and the police. I now notice two young girls walking in the street toward the negligent dog owner's house. These girls were probably 11 or 12 years old. Not good.
Sure enough out come the dogs straight at these two kids. Instead of taking a second and thinking, I just grabbed the first thing handy and ran out the door which turned out to be my wife's big leather purse. Not my best move ever. In hindsight I could have ran over and grabbed a larger knife, or even a folding chair that was nearby. Anything is better than the wife's purse right?
So I run the 100 yards holding a purse and a 3 inch pocket knife and manage to again put my skinny butt between the terrified girls (they are clinging to each other and crying now) and the apparently crazy dogs and have a standoff in the street in front of their negligent owners house.
I tell the girls to try and go back the way they came while I keep the dogs busy. As they are backing away, one of the dogs goes for them and I have to cut it off, which makes it even more pissed. That's when it's buddy came at me low and actually got my pants. I hit it with the purse and it let go and put a hole in the purse. Now both animals are within say 5-8 feet and intermittently charging at me as I'm retreating as best I can. This probably went on for just a couple minuets (felt like forever) when the owner appears and calls them off.
In the ensuing "conversation" (I may have ranted slightly) with the negligent owner he accused me of being a bad neighbor because we called the police and kept insisting that his dogs "wouldn't hurt anyone."
So that's my story. It's not as intense as some posted here and thankfully it turned out OK but I don't think I have ever felt as helpless as I did facing down those two dogs. I thought sure I was going to be mauled. This experience along with many of the other reasons posting in this topic helped me finally decided I was going to go through the process of getting a cpl. It took a little while but I'm now just waiting for it to show up in the mail.
Best,
Mike
