"The saying has become a trite one, that the training of dogs is not science, but an art allowing for all possibilities and probabilities. I am going on the record with the statement that it is neither. It is an accomplishment that can be learned by anyone who loves dogs. Provided they have a general knowledge of the technique, possesses a level head, a well balanced mind and an even temper."
- A.F. Hochwalt, The Working Dog and His Education, 1925
