The Shepherd or Police Dog 
hold the prisoner. The finding of lost and injured 
persons is worked out in the same manner in that 
the dog is urged to “Speak” at a recumbent figure 
at the end of his trail. 
Persistance and patience must be the foundation 
of all successful training, the initiative of the trainer 
in noting the manner in which the individual dog 
takes up his work and using it to an advantage, goes 
a long way toward achieving results. The greatest 
care must be taken in preventing any deviation from 
the systematic course that has been adopted, and 
there must also be none in the use of the commands, 
for the change of a word would mean immediate 
confusion to the pupil. For those that would care 
to carry out the work of training as it is done by 
the German professional trainers we recommend the 
works of Von Stephanitz, Robert Gersbach, and 
Von Crevtz, in which the description of the train¬ 
ing is carried out in the systematic and intricate 
detail that is used by the German professionals.
