Acute pancreatitis in dogs: when to start feeding
8-year-old Yorkshire Terrier admitted with vomiting and cranial abdominal pain after eating barbecue leftovers. Acute pancreatitis is diagnosed. At 24 hours, on fluids, maropitant and analgesia, he is no longer vomiting and is haemodynamically stable.
How should you approach his feeding?
chevron_right Show answer and explanation
A. Complete fasting until cPLI returns to normal
cPLI may take days or weeks to normalise and does not guide feeding. Prolonged fasting causes intestinal mucosal atrophy, promotes bacterial translocation and delays recovery.
B. Fasting for 3–5 days to rest the pancreas, then his usual diet
"Pancreatic rest" is an outdated concept: there is no evidence that it improves outcome. Moreover, abruptly returning to his usual (possibly fatty) diet is a mistake.
C. Offer small, frequent meals of a low-fat diet now and, if he does not eat enough, place a nasoesophageal tube
Correct. Early enteral nutrition (within the first 24–48 hours, as soon as vomiting is controlled) is well tolerated in canine pancreatitis, preserves the intestinal barrier and shortens recovery. If voluntary intake is insufficient, a tube allows requirements to be met.
D. Total parenteral nutrition from admission so as not to stimulate the pancreas
Parenteral nutrition is reserved for patients that cannot tolerate enteral feeding. It is more expensive, needs a dedicated central line and carries more metabolic and infectious complications.
lightbulb Key takeaway
In canine pancreatitis feed early by the enteral route: start with 25–33% of RER and increase over 2–3 days. Antiemetics and good analgesia are what allow the dog to eat; if he will not eat, place a tube rather than fasting.
