Low fat is the cornerstone — dietary fat is the main stimulant of pancreatic enzyme secretion, so reducing it lets the inflamed pancreas rest. The general target is under ~10% fat on a dry-matter basis (5–8% for severe or recurrent cases), paired with moderate, digestible protein. Pancreatitis ranges from mild to life-threatening, so an acute attack is a vet emergency.

Classic signs are vomiting, loss of appetite, abdominal pain (a dog may take a 'praying' position with front end down, rear up), lethargy, diarrhea, and sometimes fever. It's often triggered by a fatty meal or treat. If you see repeated vomiting plus pain and your dog won't eat, get to a vet promptly.
The old advice to fast for days is now outdated. Current evidence favors EARLY feeding — appropriate low-fat nutrition sooner is well tolerated and linked to fewer complications than prolonged fasting. But this is a hospital-level decision during an acute attack: don't force-feed a vomiting dog at home, get veterinary care where controlled early feeding is managed with anti-nausea meds and fluids.
Prevention is mostly about fat and weight. Keep your dog lean, avoid fatty table scraps and rich treats entirely (no bacon grease or greasy leftovers), and make diet changes gradual. Be extra vigilant around holidays and the grill. Higher-risk breeds (like Miniature Schnauzers) or dogs with a prior episode should hold a consistently low-fat diet.
Educational only — not veterinary advice. Always work with your vet, especially if your dog is on medication.
