''101 Dog Tricks'' is the largest trick book on the market and the only book with a full-colour photo of every trick presented, and colour photos of each step in the process. This is not a study guide or a training philosophy book; the step-by-step approach, tips, trouble-shooting boxes and difficulty ratings allow readers to start trick training in five minutes. Some training books require special tools (such as clicker training) or an understanding of dog psychology, but ''101 Dog Tricks'' simply spells out the actions to take. Trick training is a must for all dog owners who consider their dogs part of the family. A dog that learns tricks is better trained and better behaved overall because basic commands are understood and the human/pet communication is in place.
