Research led by Dr Watson has demonstrated that chronic pancreatitis (CP) is more common and clinically significant in dogs than veterinary surgeons previously recognised, with strong breed predispositions. Prior to this work, the veterinary profession believed that dogs had a single attack of acute pancreatitis which did not result in the development of exocrine pancreatic insufficiency (EPI) and/or endocrine insufficiency (diabetes mellitus (DM)). The work by Watson has shown the importance of chronic disease and has altered the long term treatment of affected dogs across the profession. It has also prompted companies in the UK, Europe and the USA to increase their focus on low-fat dietary management, pancreatic enzyme supplementation and analgesia improving the quality of life of affected dogs.
