you guys are comparing apples to oranges
you playing with your dog doesn't equal me fighting for my life. I am not sitting there letting a four legged dog jump up to my neck, I wouldn't bend down to his level until he was already upon me. If a dog jumps for my neck or head he is now at a disadvantage as I am manuverable on two leg a dog is not, all he can do is fall upon something else. DOGS CANNOT HOLD ON TO SOMETHING WITH IT BEING IN THEIR MOUTH. If you dog is holding you down without biting you then you are letting it do it to you. I have never had a dog pull me when I am actually serious about not being pulled, if you have you have let it.
Please don't bring up different articles or examples proving your point as I know no dog who is as strong as strong humans, (see lifting cars, and pulling buses) and I don't want to find all of the examples of humans killing dogs. Your dog is not a martial arts hero and can't compete with the fighting ability of a human.
Look you aren't going to get a good actual real life comparison out of this. But if you keep things equal, a human will kill a dog. If you set a supper huge dog against a weak person the odds are in the dogs favor. If you put a trained attack dog against a computer geek then the odds are in the dogs favor. You can also make it out against the dogs. But I would have to say you would have to put a person at a big disadvantage for a dog to beat it.
but the topic was could I handle one attacking dog of any size then yes I could. Am I dumb enough to want to try it no.
subtopic of this thread, there are a lot of people scared of dogs to the point of paralysis on here
