I think it depends a lot on your mentality. I used to deliver newspapers as a kid. Had to deal a lot with large dogs. Mostly non-customer dogs. One day I was not in a good mood during delivery.  This one house I passed had a German shepherd that used to harass me. That day I wasn't having it. I planted my Herman Survivor boot right into its chest and lifted the dog right off the ground.  Its owner had a fit and threatened to call the police  , I said go ahead. Sited the fact we have a leash law and I was in the street and not on his property. Police were not called.  That dog since that would not get within 10 feet of me. It was afraid of me after that.


I am not afraid of any dog. Think about it , all a dog or other canine can do is bite you. You have two arms and two legs. You can do a lot to a canine that they have no defensive recourse.  Even if a pit bull clamps down on your leg , you can choke it to death. If it clamps down on your arm , you can kick it or crush it's ribcage with a knee or your whole body weight just like a WWE wrestler.  You can even pick the dog up and body slam it. Grabbing a dogs legs and ripping with great force in the wrong direction to dislocate or break its legs is another option. Eyes are another good target. Getting close in as in a pit bull clamping onto you would be a fatal mistake for the animal. I would want to close in as possible as opposed to a bite and retreat attack. 

Dogs/canines are a lot more fragile than you would think. Breaking a canine's leg is easy. Breaking a dogs neck is probably difficult but if you grab it's head and twist as hard as you can in one direction until it is spun 180° or more is going to cause damage or enough pain to get it to stop attacking. The key is mentality. You need to absolutely go SAVAGE on the animal. It is going savage on you. A bite and retreat attack allows you enough time/space to acquire anything to use as a weapon. 


If police ever sent a dog onto me , I would be facing charges for killing the dog.


I have 2 arms , 2 legs and a much larger brain. I can also bite. I am also an apex level predator.

Why would you disrespect a wolf and get in its face in the first place? It's probably a pack elder.

If a man can and has killed a 140 pound leopard with his bare hands I believe some men could prevail against a wolf. I don’t remember the mans name but it was well documented, The man was a PH that was there to kill a maneater, the leopard went into the PH hut and atacked him while he was asleep. The PH spent some time in the hospital. Perhaps someone else who read of this man can put a name to him.

Compared to almost any wild animal, humans have to pain tolerance and are just weaker.. Even a whitetail deer is 10 times tougher than the toughest human. Can you be gut shot and run full speed hundreds of yards? Now stick the jaw and teeth of a wolf onto a soft cuddly deer?? Youre dead.

I found the stories about the attacks interesting
