Pancreatitis

The pancreas has two functions: producing digestive enzymes released into the small intestine, and producing hormones including insulin. In pancreatitis, digestive enzymes activate inside the pancreas rather than in the gut, causing self-digestion and inflammation. Acute pancreatitis can range from mild to life-threatening. Chronic or recurrent pancreatitis causes ongoing inflammation that damages pancreatic tissue over time.

The most commonly identified trigger in dogs is a high-fat meal - raiding the bin, a particularly fatty table scrap, or a sudden diet change. Other triggers include certain medications, trauma, and metabolic conditions. In many cases, no specific trigger is identified.

What to monitor

During an acute episode, monitor:

• Vomiting - frequency, character, whether it contains food or bile
• Abdominal pain - hunched posture, reluctance to be touched on the abdomen, prayer position (front legs down, back end up)
• Appetite - when it left, any return
• Demeanour - alert or lethargic
• Temperature if you can take it - fever (above 39.5°C) suggests significant inflammation

For dogs with recurrent or chronic pancreatitis, track between episodes:

• Diet - exactly what was fed, including treats
• Weight - pancreatitis can cause weight loss over time
• Stool consistency - diarrhoea and pale, greasy stools (steatorrhoea) suggest pancreatic insufficiency developing
• Energy level and general condition

Diet management

Low-fat diet is the cornerstone of pancreatitis prevention. This means:

• No fatty meat trimmings, pork, lamb fat, or skin
• No table scraps or food that isn't specifically low-fat
• No rawhide chews or high-fat dental treats
• A commercially formulated low-fat dog food (look for fat content below 10% dry matter)

Be consistent. Even a single high-fat meal can trigger an episode in a dog with a history of pancreatitis. Note every deviation from the diet plan in your log - if an episode follows within 24–72 hours, the link becomes clear.

Managing treats and medications

Many common medications have been associated with pancreatitis in dogs, including certain antibiotics and immunosuppressants. Always inform your vet about your dog's history of pancreatitis when any new medication is prescribed.

For training treats, choose low-fat options. Account for their fat contribution in the overall daily dietary fat budget. Some dogs with recurrent pancreatitis do better with vegetable-based treats.

Monitoring for complications

Dogs who have had significant or repeated pancreatitis may develop:

• Exocrine pancreatic insufficiency (EPI): The pancreas fails to produce sufficient digestive enzymes. Signs include dramatic weight loss, voracious appetite, and pale, large, greasy stools. Treatable with enzyme supplementation.
• Diabetes mellitus: The insulin-producing cells may be damaged. Watch for increased thirst, urination, and weight loss.

Log any of these signs and discuss with your vet if they appear.

When to contact your vet

Go to the emergency vet immediately if:

• Your dog is vomiting repeatedly and cannot keep water down
• Severe abdominal pain (hunched, crying, unable to settle)
• Severe lethargy or collapse
• Signs of dehydration (dry, tacky gums; skin tent persists)

Contact your vet the same day if:

• Vomiting and lethargy have been present for more than 12 hours
• Your dog has had pancreatitis before and signs are returning

Schedule a routine appointment for:

• Diet review for a dog with recurrent pancreatitis
• Monitoring bloodwork (lipase levels) for dogs with chronic pancreatitis
• Any concern about developing EPI or diabetes

Frequently Asked Questions

How is pancreatitis diagnosed? Diagnosis typically involves blood tests (elevated pancreatic lipase, raised white cell count) and often abdominal ultrasound. Mild cases may be treated presumptively based on history and examination without extensive testing.

Can pancreatitis be cured? Acute pancreatitis usually resolves with supportive treatment. Some dogs fully recover and have no further episodes. Others develop recurrent or chronic pancreatitis - this is managed rather than cured through long-term dietary management and monitoring.

My dog had pancreatitis once - should they be on a low-fat diet forever? For dogs who have had a single mild episode with an identifiable trigger (a one-off fatty meal), a return to a balanced standard diet may be appropriate. For dogs with recurrent episodes or severe pancreatitis, a long-term low-fat diet is generally recommended. Discuss with your vet based on the severity and frequency of episodes.

Is pancreatitis painful? Yes. Abdominal pain in acute pancreatitis can be significant. Appropriate pain management is part of treatment. If your dog is showing signs of pain (reluctance to move, hunched posture, vocalisation when touched near the abdomen), ensure your vet is aware and pain relief is included in the management plan.

What can I feed my dog with pancreatitis when they're recovering? After vomiting stops and the dog shows interest in food, reintroduce food gradually with small amounts of a bland, very low-fat diet - plain boiled chicken breast and white rice, or a prescribed recovery diet. Increase quantity over several days if well-tolerated before returning to the regular low-fat food.
