Some places that I've hunted did not allow you to dress game in the field. Most of their reasoning was that it attracted predators. Iffy at best, predators are already there. Others think it scares game away. I have killed evening deer over a mornings gut pile. So that doesn't hold much truth either.
Myself, I never gut deer at all anymore. After skinning it out I get all the meat that I would normally get without skinning. Including the tenderloins and flank meat, the only meat left is ribs which isn't much loss.
