If I could I’d grab it under the throat and try to choke it off or destroy its trachea if I didn’t have any weapons on me.
If it was a dog with a chain collar you might be able to choke it off with that.
For P-F probably a knife or a gun
The scary dogs are the ones that either “typewriter” where they release and bite again at a different spot or the ones that just bite, release, bite again at a different area. That’s how you get mauled. But a dog with a lot of bite pressure is doing a lot of damage too especially if they’re chewing as they bite.
I’m used to dogs that bite and hold one spot. They usually will adjust the bite to drive deeper in the mouth but they’re biting and holding on.
