In severe cases, the swelling is so bad that it can block the flow of bile from the liver and gallbaldder and cause
even more serious trouble. Some dogs can
overindulge for years and suddenly develop pancreatitis. Symptoms of pancreatitis are vomiting, inability to keep down water, lack of appetite, lethargy and fever as the condition worsens.
Treatment is mainly inpatient supportive care. The dog must have complete digestive rest which means nothing - not even water - by mouth.
