This Book is very helpfull and informative to people completely new to clicker training. With my ever failing voice i simply cannot repeat the same command with the same tone or pitch, thus i was incapable to come through to my dog, i was not credible. Clicker training with the help of this book made training fun again! This book among others also was quite encuraging! To me at least.I must agree though with a fellow reviewer below that one thing that is missing is a show training chapter. I would also say that further reading of related books would perhaps expand my skill, but just as a tryout or for begginers this books is fine!
