Very easy & and the instructions were clear to understand. Maril clearly showed us how Linus could respond positively if we followed this training. It was amazing & encouraging to see. We went from a dog of chaos to a puppy who was under control in 2 hours. We know we will get results without treats, threats and zap collars! I am a child counselor. I like to know the "why" behind the behavior - this method explains the why and how to correct the mis-behavior in a way the adult is respected and in control. For dogs, I didn't know how to do this until Maril explained it. It is a humane method everyone can use and it works!!
