Pancreatitis — inflammation of the pancreas — is a common and potentially serious condition in dogs. It ranges from mild acute episodes to severe necrotising disease and can become chronic with recurrent flares. Effective management requires prompt recognition, appropriate treatment, and long-term dietary control.
Causes and Risk Factors
The aetiology is often multifactorial. Dietary indiscretion — consuming high-fat foods or garbage — is a classic trigger. Obesity, hyperlipidaemia, certain drugs (e.g., potassium bromide, azathioprine, some antibiotics), endocrine diseases (hypothyroidism, hypercalcaemia), and breed predisposition (Miniature Schnauzers, Yorkshire Terriers, Cocker Spaniels) all increase risk. Trauma, ischaemia, or obstruction of the pancreatic duct are less common triggers.
Clinical Signs
Acute pancreatitis presents with vomiting, abdominal pain (the "prayer position"), inappetence, lethargy, and diarrhoea. Severe cases may show dehydration, shock, fever, and jaundice. Chronic pancreatitis may present subtly with intermittent GI signs, weight loss, and reduced appetite.
Diagnosis
Serum canine pancreatic lipase immunoreactivity (cPLI) — specifically the Spec cPL test — is the most sensitive and specific blood marker. Ultrasound reveals pancreatic enlargement, hypoechogenicity, and peripancreatic fat saponification in moderate to severe cases. Abdominal radiographs may show loss of detail in the cranial abdomen.
Treatment
- Fluid therapy: IV crystalloids for dehydration and electrolyte correction
- Anti-emetics: maropitant or ondansetron to control vomiting
- Analgesia: buprenorphine or methadone — pain management is critical for welfare
- Early enteral nutrition: small frequent meals or nasogastric tube feeding in severe cases
- Antibiotics only if bacterial infection is suspected
Long-Term Dietary Management
Dogs with recurrent pancreatitis benefit from a strict low-fat diet long-term (<10% fat on dry matter basis). Prescription gastrointestinal diets or home-cooked low-fat recipes (e.g., boiled chicken and rice) are used. All table scraps and high-fat treats must be eliminated. Weight management is essential in obese dogs.
Welfare Impact
Pancreatitis causes significant pain and nausea, profoundly affecting quality of life during episodes. Chronic disease requires lifelong dietary restriction that may reduce food enjoyment. Good welfare management emphasises effective analgesia, monitoring for complications (diabetes mellitus, exocrine pancreatic insufficiency), and client education to prevent recurrence.
