The busy small animal practitioner is likely to see a dog or cat with GI signs most days and this resource should give them greater insight into the conditions they are treating. This manual is divided into four main sections: 

• Diagnostic procedures and techniques: this section covers clinical pathology, imaging and biopsy
• Diagnostic approaches to problems: the chapters in this section provide a practical, diagnostic approach to problems affecting the GI tract, pancreas and liver
• Patient management: this section looks at the treatments available for GI, pancreatic and liver disease.
• Diseases of specific systems/organs: the chapters in this final section cover specific conditions of organs of the GI tract, including pathophysiology, clinical signs, diagnosis, treatment and prognosis.
