I bought this after reading all the rave reviews from other readers. Yes, it has a lot of sensible advice, BUT I found the so-called "positive" methods were deeply rooted in yank and shove methods that have now been superceded by better training approaches. The acknowledged debt to Barbara Woodhouse rang some warning bells for me - the descriptions and photos of lead corrections, and the use of "training collars" rang even more. I started out training dogs in this way many years ago - then I discovered clicker training and positive reinforcement, and find them easier, quicker and happier ways to a well behaved companion. I find the books of Jean Donaldson, Ian Dunbar and Karen Pryor more informative, more sympathetic, and more useful than this.
