I pretty much used Bronko's friends technique. I think it's a good idea to combine the advanced training with force fetch. This way, the dog already knows he must find the game. This would especially be helpful with an older dog, or one that does not already have a strong tracking instinct. After force fetch. I'd not waste much time with drag rags after you see the light bulb "come on". Use freshly killed game. Rabbits, are usually easy to get. When the dog is finding and retrieving the rabbits. Introduce the long leash, and let the dog learn to work with this.

When the dog is following game drags to their end on the long lead. Introduce the blood using the very same situation you used for the game drags. Leaving a deer hide, and some raw hamburger at the end of the blood drags is how we reward the dog.

Like all training with dogs. Do everything in steps. That way, if something goes awry. You just go back to the last step the dog completed, and start again.

One other word of advice. When you start doing tracks for other hunters. Don't let them follow along with you. Make them wait for you to come back and get them.

You mentioned Shutzhund training. it's my understanding that our techinique was taken from their training.
