Problem behaviours are often the result of how an animal thinks and feels, genetics and environmental influences. Steering away from just description diagnoses and focusing instead on emotional and cognitive causes, this book provides a practical approach to diagnosing, treating, and managing behaviour pathologies in dogs and cats. Beginning by addressing cases in the first opinion practice, this book then considers physical disorders that may lead to or exacerbate abnormal behavior. From there, the focus shifts to mental and emotional health, from an assessment of normal behavior and giving juveniles an optimal start in life, to diagnosing mental and emotional disorders, addressing emotions such as anxiety and frustration, and how to manage these issues - by modifying behavior, managing the animal's environment, training, and, when necessary, the use of medications. The second half of the book then addresses owner concerns, including management problems, aggression, affective disorder, elimination disorder, abnormal and repetitive behaviours and ageing-related problems.With an emphasis on helping first line veterinarians identify common presentations and offer help to owners, this book:- Addresses both normal and abnormal behaviour in cats and dogs from an emotion and cognition perspective;- Provides behaviour modification protocols, and drug doses and indications;- Includes handouts to be used both within the practice and with clients to help the veterinary surgeon manage the case.Written by international experts, the book translates their insights and experience into approaches taken in behavioural medicine. Also including the most up-to-date drugs, it is an important resource for both small animal veterinarians and students of veterinary medicine or animal behaviour.
