Help For Your Fearful Dog: A Step-By Step Guide to Helping Your Dog Conquer His Fear by Nicole Wilde. If you want an easy-to-read primer on dealing with fearful behavior, then read Patricia McConnell's The Cautious Canine. If you want something much more in-depth with virtually step-by-step procedures on how to help your dog work through his or her fears, then read Nicole Wilde's book. Most people will not want this amount of detail, but for those who do, it is the best resource I have found. However, if your dog has anything more than a very mild fear, I do recommend that you seek professional guidance as well. Fearful behaviors can be tricky to deal with, and having an experienced person helping you is essential.
