What professionals are saying about Aggression in Dogs
Brenda Aloff is a pioneer in our field. Clicker trainers have proven that "it can be done" with competition obedience, agility, flyball, service dogs, indeed in all fields of what might be called "performance training." But Brenda takes our technology into a field long considered the ultimate bastion of the force trainer: rehabilitating and training the "aggressive" dog. Brenda shows clearly, most importantly through her detailed case histories, that one can address the issues posed by these dogs in a constructive, effective way without losing oneself in the murk of "dominance" theory and all of the mythology that surrounds it. This book is a worthwhile and necessary addition to any serious trainer's library.
Morgan Spector, author of Clicker Training for Obedience.

There are standards in the world...Campbell's on soup, Bud on beer and now, Aloff on aggression. Almost every dog training book I've ever read has provided me with some gem, or at least some tidbit, I can use. This book, however, is the mother lode. If you need to understand aggression, Aggression in Dogs is the book for you!
Missy Parker, RVN, President, National Association of Dog Obedience Instructors

This book is a "must have" for all trainers, kennel personnel, veterinarians and support staff. Not just for aggressive animals, Aggression in Dogs is an excellent reference tool for anyone interested in understanding canine behavior and the prevention of aggression. The protocols are field-proven effective.
