I don't do strict Schutzhund, nose in each footprint style tracking with him. We do area search type of situations- have a decoy agitate him and run into the woods, and a few minutes later send Gunnar in to find him. We do lots of hide and seek stuff at home. He can find a twig (I'm not kidding) that I hide in the yard. He'll need to follow my track and then locate the twig and bring it back to me.
Tracking isn't that hard, it's just something you need to do every day. You can look up how to get started and follow those guidelines. There are a lot of ways to do it. Some people start with a "stomp box" where you tramp down a small area of grass and put bait in there, and the dog will sniff nice and deep to find the bait. Then you can gradually start taking steps, using bait in each step to get the dog to follow. Eventually you work down to not using bait in each step, and finally, no bait at all, with some kind of reward at the end of the track- food, ball, tug, etc. This is how it was shown to me by a guy who did Schutzhund. Other people may have other ways of teaching it. My K9 cop friends don't care at all about tracking each foot step, only that they get the bad guy, so air scenting, crisscrossing the field, all of that is fine as long as the result is good.
