Interesting perspective. If you are going up against a well trained beast, yep KYA goodbye. If you are going up against a dog that has simply been trained to be aggressive without any other training, you have a chance to survive with some injuries. Like Robo says, only as good as the handler. I have been attacked by just aggressive dogs three times in my life. Got bit twice but except for some interesting scars, have nothing to show for it. One was a Weimeriner, the other a chow. Key was neither was a trained K9. I can't think about any scenario where I am going to even try to resist a trained K9, since I tend to be a law abiding sort. A simple aggressive dog, that is another story. Lucky for me the jammed forearm worked both times. No guarantee it would work now, since I am 30 years older, and a lot weaker and slower, So a 45 JHP is a much better option. Back then, concealed carry permits were next to impossible to get in our area, the upper midwest. So if a dog attacked, you better have an edged weapon out quick, or you were relying on basic skills.
