Meaning, of course, that Art considers it ill-advised to drop to all fours and grip your prey by the throat with your teeth, strangling it to death for 10 minutes.
Small game often means .22. If they're still mobile, I plug 'em again, head shot. If not mobile, the above methods of breaking their necks are advisable. As I just don't plan on getting bit again, I'm all for the heel-to-the-neck method, unless the ground is unduly soft. Then one may need to use a tool (long hunting knife works) to strike the neck. I have been known to dispatch small pests shot at night in a semi-rural area with a blow to the back of the head with the hard buttplate of my .22 rifle. This was to reduce noise, and was done with an open bolt and an empty chamber.
