Six percent of people think they can beat a grizzly bear

I used to think that I could take on a large dog until one day a large Pit Bull got hold of my forearm. Thank goodness that dog had a shock collar on him and the owner was quick with zapping it, or from what I could tell from the power of those jaws, my goose would have been cooked.
There are certain dogs I simply will not fork with. One is the Neapolitan Mastiff. Friend of mine had one and at six months he was well over 100lbs. and stood over my friend, who's easily 6' 4", on it's hind legs. So considering that and the fact that he was fast as all get out with that huge head and drool everywhere, that was a big nope for me. Don't invite me over ever again unless he's kenneled and highly sedated.
