"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 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 in love for the master,
and such, (as we have already seen) founded on the satisfaction of a natural craving, which
therefore must be consolidated by a wise training from earliest puppyhood. with a young
dog who is obedient in this sense, who waits upon the eyes and mouth of his master, who
comes joyfully when called, even from his feeding dish, or from 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 tit-bit, or, as the highest reward, by sharing in the activity of
his master: with such a dog every thing is possible later on. for joy in 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 training both directed to a special purpose with a definite goal in view".
