My dog was diagnosed with pancreatitis. He had fluids, antibiotics, anti nausea pills & pain pills (which he refused) along with a low fat prescription diet. His meds are done now- finished about 2 days ago. He is no longer vomiting & is eating & drinking great- but still seems to be in a bit of pain from Time to time (he doesn’t always rush to see me like usual) Is this normal? What should I be watching for?
