We can use dogs to track fallen deer. Although I get the feeling there would be a number of people who would freak out about it. As far as I know we can't use dogs to hunt big game unless it's for Mountain Lion. I met a game warden that brings his dog (a lab) with him when he hunts deer, but not to track.
I didn't realize schitzhund was into the giving points for style. That's a bummer. I really prefer how well a dog performs rather than how good it looks doing it.
