I have a Drahthaar and have been through the VGP with him and did the blood track. A lot of the German dogs are not specialists but versatile dogs. The German's don't believe in feeding a dog to point then another to track game and another to retrieve, they breed all into one. They believe in recovery of wounded game to the extent, if your dog cant find it you go to town and get a better one that can.
The Germans have a couple of methods to track deer. One is on lead, the other is totrebeiser "dead game guide" , this is using the brindsel and the dog leads you back to the dead deer. The other is totrebeller, "dead game bayer" The dog find the deer on its own and sits on top and barks until the handler comes to him. This maybe for hours that he barks. From what I have been told Southern Germany uses this method more because of the deep forests and mountains. The handler may listen to where the dog is and drive around the mountain to get at the location more easily. As I said this may take some time. I have heard that these dogs did not catch on real well in the states because they are really noisy even when not hunting. Nobody likes a neighbor with a noisy dog.
During the Utility test the dogs track, if I remeber correctly, a 600 meter track using 8 oz. of blood that must have aged a minimum of 6 hours. Another test would include the same but aged 20 hours and another aged 40 hours.
I have used my DD to track a couple of deer worked very well. Tracked on for over 1/2 mile and produced the deer still alive and the last time I saw him, doing very well. I think it was a muscle shot to the ham.
