Building on the success of the first edition, the Editors have brought together a host of international experts on behavioural medicine of dogs and cats. The following considerations are discussed for a range of behavioural presentations: evaluation of the patient; evaluation of client attitudes, beliefs and behaviour; risk evaluation; behavioural biology; acute management protocols; long-term treatment strategies; prognosis; follow-up; and preventive measures. History-taking forms, questionnaires and a collection of client handouts are included so that the veterinary surgeon has the tools to hand to carry out the recommended actions.
