Handbook of Applied Dog Behaviour and Training, Volume two: Etiology and Assessment of Behaviour Problems is the definitive reference for dog trainers, behaviourists, breeders and veterinarians. Coupled with Volume one, this text provides theoretical and practical framework for understanding the development and treatment of dog behaviour problems. Topics covered include Fear, anxiety and phobias, Separation-related problems, Hyperactivity, and Dominance, territorial, and fear-related aggression. The focus is to present and evaluate the relevant applied and scientific literature, and to highlight what remains to be learned, while the author introduces alternative ways for analysing and understanding the etiology of dog behaviour problems.
