Clicker training is a method of teaching behavior to dogs using positive reinforcement. The successive approximation of desired behavior is marked with a clicker and rewarded with a treat, a toy, or a pat. Inappropriate behavior is ignored, not punished. In 1985, Karen Pryor published the seminal work on this method, Don't Shoot the Dog (Bantam), and issued a revision in 1999. Both editions are highly theoretical and are aimed at the educated, informed lay reader. Tillman, an ergonomics illustrator as well as a dog trainer and clicker-training instructor, has made Pryor's principles and techniques accessible to the rank amateur. Using easily understandable text and clear, step-by-step drawings, she guides the novice through all the steps necessary to teach dogs almost 100 different behaviors, from basic obedience to housebreaking to tricks. She also applies the principles to the elimination of problem behavior. While Paul Owens's The Dog Whisperer (LJ 10/1/99) covered much the same subject matter, Tillman's book teaches the skills through illustrations. Highly recommended for public libraries.
