In your experience, it may be that the dogs you've encountered and dealt with would lead you to make such a general statement that you could handle and control any dog attack. Unless you are built like a 500 lb gorilla with 6 inch fangs, I must inform you that there are many dogs out there that you would positively not be able to control, that would probably kill you inside of 15 seconds, or make you wish you were dead by then. I've met some, and I can't imagine anyone who could stand up to them were they triggered for an attack.
Until you've seen the full on capabilities of dogs that are bred and trained to attack humans, you really can't make such a claim, and having met some of them, I have a seriously difficult time believing the veracity of such statements. The facts simply indicate to the contrary.
If a fighting dog really wants to take you apart and he has the jump on you, he's going to have his way, and there's really nothing you can do about it. That is not opinion my friend, it is fact.
