Fearful or reactive dogs are defined as dogs who have a greater than usual reaction to stimuli. Their behavior is often labeled as aggressive (even when they are not) and may include lunging, barking, growling, and pulling on the leash-often toward the "SCARY" object. You'll get a glimpse into the real lives of reactive dogs that Ali has worked with in her classes-their growth, successes, and failures. It serves as a guide both for trainers who wish to run classes for their clients with reactive dogs and for owners of reactive dogs who must formulate a training plan of their own.
