The accurate diagnosis and effective long term therapy or control of alimentary disease in the dog and cat are difficult goals to achieve, due to a lack of comprehensive information on the specific conditions affecting the alimentary tract together with a lack of suitably practical methods of investigation. The book presents, in a practical way, the information which clinicians, faced with the daily business of investigating such problems, will need. The authors allow the reader to approach a problem from a number of angles, arriving at diagnosis after considering the history of a complaint and a full physical examination, and the possible paths of further examination. Wherever possible, clinical features are correlated with biopsy, clinicopathological findings, and also with autopsy where this is relevant.
