The training of Dasko purely positively was inspired by Sheila Booth’s book Purely Positive Training (Podium Publication, Ridgefield, CT, 2000). She strongly makes the point that when “the dog gets punished for not obeying”, he not only gets confused and becomes resistant, but more importantly “the dog perceives the trainer as an unfair pack leader.... Trust breaks down....He becomes inhibited and stressed.... He can’t think or react because he is too worried about being wrong.”

As she points out, “there are no wrong dogs. If the dog does not do something right, then in some way we have failed to teach it properly. We assume the responsibility.” We should not punish the dog for our failure.
