True story: When my son was small, maybe 5, I was in the yard and saw him running down the street toward home and there was a big dog after him. I started running toward the dog and I really was going to kill it with my hands - there was no question I was going to do that. The dog saw me running toward him, turned around and took off. HE knew I was going to kill him.
I know that is what happened with this owner whose dog was going to die unless he did something fast. Something clicks in your head and you turn into a killer in an instant. I've been there and I was an instant killer with that dog after my child.
If a dog has to be killed with a knife, no sense bending knives trying to stab it in the heart. Just cut the jugular. Even a cat has enough sense to do that.
Ah England, yep no guns there.
The thing about killing a dog with your bare hands is...they are so fast, in a fight they can move and bite faster than you can see them. You will not know that you’ve been bitten until a couple seconds after it happens.
Their teeth cut flesh better than razors, and they are hot. I learned this the hard way.
What I further learned when I captured two loose pit bulls in my neighborhood is that those particular dogs, despite being small, are so ridiculously strong that I was just plain frightened. Even though I did capture them both and leash them into my yard, I was an idiot for doing so.
After I leasehed them, the male, which was a little bowling ball of a dog, bumped my right leg from behind which took me clean off my feet in an instant. Had those dogs attacked me then, that would have been all she wrote. Luckily, I had befriended the pregnant female prior to that, so neither dog took advantage of my fall.
I then turned them in to animal control where the owner later retreived them both.
My point though in relaying this to you is do not mistakenly underestimate a dog as an easy opponent in a fight, they are physically superior to humans, especially if they become vicious, and a pitbull is like wound steel with razors in its mouth.
