So much for trying to have fun with the topic!

More seriously: first you have to decide why you are field dressing an animal. Do you have a plan to use every part of the critter, or is it to be quick and dirty take the best and easiest pieces? Do you want the hide intact? How are you going to cook the critter? Are you going to make stock of the minor bits and pieces? Are you going to cure the meat before butchering? Do you intend to marinate? Is it better to do a quick field dressing and cool down the carcass for more elaborate butchering at home? Are you going to also cook the critter in the field? Is it important to you to learn from a small animal the techniques for fully butchering larger animals?

Let your purpose inform your techniques.
