A mind to be free from conditionings, must escape from the shame caused by social pressures and beliefs. Only an impudent mind can explore cognitively, can act consciously, can live wisely.
In this sense, animal training tends to create mental chastity, with animals that start to feel shame for their own impudent thoughts.
Other than making animals right and competent, animal training reduces animal impudence and with it reduces the intrinsic motivation, the innate cognitive kit and the quality of life of animality.
Preserving an impudent animal mind, means give access to a higher level of animal quality of life and wellbeing, it means do not feel shame, but be proud to have impudent thoughts.
