Thomas Riepe speaks candidly about the overwhelming jungle of training methods and equipment related to dogs. He asks probing questions and refuses to be placated by flimsy arguments that define a painful tug on the leash as an impulse or outdated training methods based on pain and pressure as decades of experience. He does not hesitate to name those who promote a non-violent approach to training that is certainly not perceived as such by the dog, and he examines how these different approaches have developed. Additionally, he includes well-known colleagues such as Clarissa v. Reinhardt, Maria Hense, Christina Sondermann, Ute Blaschke-Berthold, Sabine Neumann, Jörg Tschentscher, Steffi Kohl, and Martina Albert, who also express differing opinions on various topics.
