Today's dog trainer can trace the roots of modern training to Training Dogs by Colonel Konrad Most. Written in Germany in 1910, Training Dogs influenced how both dogs and trainers were taught in Europe and the United States for the next 50 years! It contains valuable and historically significant information, a true classic. 21st century trainers and behaviorists will find it amazing to realize that early in the 20th century Konrad Most was using and applying behavioral training principles with dogs long before B.F. Skinner! Most also created systematic and scientific methods to teach trainers how to train dogs with his "e; Theory of Training."e; While Most's methods may be viewed as harsh by modern dog trainers, the theory behind it was revolutionary for it's time and it is still applied today.
