I learned the basics of clicker in this book. it is a magical accessory that allowed my dog to learn a lot of little tricks. I associated with other books (sit, down, to move & play with his dog). it only took me a few days to get results. I sometimes waits several months before returning to my dog with this book to teach him new tricks. I had read online that the clicker was working well and I confirm, it actually works! ;-) I do not regret my purchase, and do not hesitate to advise about me
