I have always field dressed my deer and pronghorn at the site they went down. In the woods where I hunt deer, we have coyotes, foxes and mountain lions. I take the heart and liver out of each animal but leave the rest. On the ranch where we hunt deer and pronghorn, the rancher likes us to leave the gut piles so the coyotes and bobcats and eagles, hawks,ravens and vultures can eat them and not bother his livestock. He also likes the predators around to hunt the prairie dogs that live on his property.
