Intresting question. Sorry I haven't got an answer for you. Have you tried to contact the NAVHDA. They routinely test their dogs on game tracking. I believe this would be the blood trailing type of tracking, so it might not be too useful to you.

You might also try contacting one of the organization that trains the rescue/search dogs. This, however, could really mess up a hunting dog. The last thing you need to do is follow a birdy dog through the field only to have him take you to some bowhunters tree stand.
