I've had four attack situations with dogs, an' still have all limbs and appendages attached, so I'm either lucky as hell, or done somethin' right.
First and most serious was when my parents 165 LB. Newfoundland turned on me (yes, a Newfy folks!)
The dog kept alternately lunging for my throat and my testicles, and I basically kept moving back, and swinging for it's nose when it came for my throat, and kicking in his face when he came for the family jewels. Big thing was that I stayed up and kept moving, I knew I was gonna find myself celestially challenged if I went to the ground with him. I was also screaming at him like a Banshee. I was scared as hell an' all, but was also pissed off. ie: C'MON MOTHERFOCKER!!! I'LL FOCKEN KILL YOU!!! KEEP TRYING GOD DA--MMIT!!!"
The dog kept goin' at me for about a minute (one long damn minute!) before he started slowing down and just stood there growling and locking eyes with me. My mother then saw what was happening and opened the door to the house to let me in. The dog layed on the porch out there growling for another twenty minutes.
Amazingly, he never so much as got a single scratch on me...well...he grazed me slightly, but not too terribly. Most scary damage I got was the fact that he got hold to my jeans about two inches from my twig and giggleberries and tore them all the way down to my boot.
Wish I could give a technique, but I basically just fought like hell. I think it was good that I kept moving and side stepping. I also think he would have killed me if I'd tried to run.
Second run in was when my wife and I were running and a couple pitbulls came after her like a couple focken' missiles. My wifes hysterical scream and holding her hands out in front of her didn't dissuade them at all. On the other hand my "GET THE FOCK OUTTA HERE!!! on top of other miscellaneous rants and raves seemed to stop them in mid air. Well...either that or they had a respect for the .45 caliber revolver loaded with Hydra-Shoks I had pointed at them. Was a good thing I'd turned them around though, cuz this had occurred in late fall, and my wife had at that very moment slipped on the ice and busted herself up pretty bad. (passed her physical for the State Troopers a few days later with a badly strained hip! YAY KARIE!!!)
Funniest one was last summer when the wife and I were taking a late night walk around our new neighborhood. I didn't have a firearm for some sick reason, but had chosen to arm myself with my Rekat Hobbit Warrior. She and I were walking along a patch of woods when I suddenly heard crashing brush and a growly bark behind us. Instinctively I spun around and drew the Hobbit, waaaay fast (for me anyways)...the wife had barely acknowledged the sounds before I'd turned around in full Mall Ninja attack postition. Found myself in some kinda retarded wanna be military knife fighting stance except the Hobbit was in reverse grip. (to the untrained eye it may have appeared that I knew what I was doing, even though in reality I was/ am freakin' clueless)
Once my eyes focused a little better I saw a Husky/ Shepherd mix thing standing in the road stopped dead in its tracks. The dog looks at me with it's head tilted, whimpered once, pissed all over the road, and ran back in the woods with it's tail tucked between it's legs. (wife said judging by my appearance at that moment she didn't blame the dog, and would have done the same thing herself if she didn't know I was on her side)
I guess my idea on the topic is that I'm too slow to run, so I'm standin' my ground. If it's a breed of dog that's known to clamp on and not let go (Pitbull) I'd be most likely to feed it my left arm, and slash the dogs throat with my right. If knifeless I'd try choking it with the right hand. Gouging the eyes seems like a good idea, except I think I'd wanna make it damn fast since it gives no control over the head.
There was a Trooper out here a few years ago that killed a Pit by cramming his hand all the way the hell down the dogs throat to choke it. (nasty, eh?)
If it were a dog better known to bite anywhere and everywhere until ya' go down I guess I'd do the same thing as I'd done with the Newfy.
I'm not sure if I've necessarily reacted appropriately or not, but thus far, it seems to have worked.
Would be interested in hearing what the better educated folks an' the experts think.
