It presents problem-solving information, and the basic science underpinning it. This edition recognizes recent scientific advances, particularly in communication, perception and cognition, and in clinical behaviour. The author gives full consideration to the effects of domestication on each species and the book is organised by common types of behaviour for each animal throughout its lifecycle, including the physiological basis and development for different types of behaviour. Problem situations and abnormal behaviour for each animal species are also covered, together with recommended treatments.
