We don't worry about it and we are offlead in the woods a good bit. Usually I am the one that comes back bleeding, not the dog. I just give a good go over when we get home looking for cuts and for the rare one wash and treat accordingly.
They do make hunting vests with belly protection for hunting dogs.
I do have some clotting powder in my first aid kit but have never had to use it. My biggest fear is a coyote trap.
