If you got lucky then you could break the neck of anything smaller than the medium dog, or the snake, but anything larger and in the absence of tools, what’s the strategy?
What part of a snake is the neck?
You could break it down in to what tools you are equipped with. So versus a wolf for example. Wolfy McWolfson has four sets of claws and a set of jaws. You have, at the start any way, teeth, fingers, fists, elbows, head, knees, feet and the ability to grapple, throw etc.
