I suggest if you are interested in the real deal Sch and not the backyard half reared I would call a few clubs in your area and set up a meet with them. I agree with the aboved mention...doing this yourself will set your dog up to fail..
It is very dangerous to try and do sleeve work with your dog if you do not know what your doing. Not knowing what your doing you can push a dog into defense drive and get yourself bit or make a wrong association and make your dog aggressive. Schutzhund is not all about bite work, it is about Obedience and tracking as well. Without a proper trainer you are asking for trouble and I suggest you start training with a club or trainer.
