Trust is a sine qua non, and obedience is the foundation of every training; both go hand in hand, and both are inseparable. Blind and servile obedience is not rooted in trust, but in fear,and only rebels when out of reach of the whip. Such service we do not demand from our dogs, but an obedience which is joyful and always willing, founded on love for the master, and as such. . . founded on the satisfaction of a natural craving, which therefore must be consolidated by wise training from earliest puppyhood. With a young dog who is obedient in this sense — who waits upon the eyes and the mouth of his master, who comes joyfully when called, even from his feeding dish or his companions at play,
because he knows he will be rewarded for his obedience by a kind word and by an affectionate pat, by a special tidbit, or as the highest reward, by a sharing in the activity of his master — with such a dog every thing is possible later on, for joy in the work is combined with its accomplishment. This, as the outpouring of the power accumulated in the dog, is the result of sound nerves and a serviceable body build; and here again, it is a matter of breeding and training,
both directed to a special purpose with a definite goal in view.
(The German Shepherd Dog in Word & Picture, Max v. Stephanitz)

This quote by v. Stephanitz summarizes my philosophy of training. working, and living with my German Shepherds. This page has links to some photographs ofmy dogs working in schutzhund. I find that working my dogs in schutzhund gives me greater insight into their character, spirit, and mind, and deepens my enjoyment of their company. Plus, we love it! : )
