We were taught the same thing in the police academy back in the 60's.
It's best (time permitting) to wrap a shirt or something similar in size, around your hand and arm. The dog is supposed to be unable to bite while he is choking to death.
My only encounter with a pit bull was pulling one off a German shepherd. Only thing I could think of in that fraction of a second was to grab the pit bull's hind legs and lift him away from the other dog. When he let go of the other dog he tried to curl upward to reach me. All I could think of to do was to start swinging him around in a circle, letting centrifugal force keeping his business end from getting me. I also was in the vicinity of a pine tree and I figured if things got any worse I would adjust my swing and plaster him up against the tree.
Didn't have to....the dog's owner showed up and I handed him the two hind legs I was gripping and said "Here's your dog...have fun".
I've since gotten advice that I was very lucky...and never try that gain.
I don’t know why... but I think that’s going to stick with me forever.
I hope I’m not attacked by a chihuahua.
How to survive an anaconda attack (not really):
1. If you are attacked by an anaconda, do not run. The snake is faster than you are.
2. Lie flat on the ground. Put your arms tight against your sides, your legs tight against one another.
3. Tuck your chin in.
4. The snake will begin to nudge and climb over your body.
5. Do not panic.
6. After the snake has examined you, it will begin to swallow you from the feet end - always from the feet end. Permit the snake to swallow your feet and ankles. Do not panic!
7. The snake will now begin to suck your legs into its body. You must lie perfectly still. This will take a long time.
8. When the snake has reached your knees slowly and with as little movement as possible, reach down, take your knife and very gently slide it into the side of the snake’s mouth between the edge of its mouth and your leg, then suddenly rip upwards, severing the snake’s head.
9. Be sure you have your knife.
10. Be sure your knife is sharp.
