My dog has pancreatitis. Are flare-ups normal on a low-fat diet?

Updated On September 23rd, 2025

Pet's info: Dog | Pomeranian | Male | unneutered | 4 years old | 18 lbs

Archie suffers from chronic pancreatis. He's on a low fat diet now and he's a lot better. However, he sometimes has an off day, maybe once a month, where he gets diarrhoea and has a vomit or two. Of course on these days he doesn't eat and drinks minimal. Is this just a part of having chronic pancreatis? Sometimes it might just flare up, even if he hasn't eaten anything that he shouldn't have? If he does eat something he shouldn't, how long will it be till it affects him? Could it be a week or so

Good job on keeping Archie on a low fat diet. That is the best option for long-term management of his pancreatitis. It is definitely possible that he is having flare ups causing the intermittent vomiting and diarrhea. I would have him evaluated by his veterinarian to ensure there isn't another cause though. Some of these dogs can have alterations in their cobalamin and folate levels. Correcting this can alleviate some of their clinical signs. Other animals will need an abdominal ultrasound to ensure the rest of their belly is normal. As far as your other question, the dog will usually flare up within about 24-48hrs of eating a higher fat meal. Good luck with Archie!
