The pancreas produces digestive enzymes and releases them into the small intestine. In pancreatitis, those enzymes activate too early — inside the pancreas itself — and the organ begins to digest its own tissue.
It is painful, it can be severe, and it is one of the more common reasons dogs are admitted after Christmas, barbecues and holidays.
What triggers it
A high-fat meal is the classic trigger. Roast fat, bacon, sausages, butter, cheese, chip fat, a stolen barbecue plate, a raided bin.
Other associations:
- Obesity, which raises baseline risk
- Certain medications, including some steroids and anti-seizure drugs
- Endocrine disease — diabetes, Cushing’s, hypothyroidism
- High blood triglycerides, notably in Miniature Schnauzers, who are strongly predisposed
- Abdominal trauma or surgery
- Breed — Miniature Schnauzers, Yorkshire Terriers, Cocker Spaniels and some terriers appear over-represented
- Idiopathic — in many cases no trigger is ever identified
The signs
Classic presentation:
- Repeated vomiting
- Abdominal pain. The giveaway posture is the “praying position” — front end down, back end up — which is a dog trying to relieve abdominal pressure
- Lethargy and reluctance to move
- Loss of appetite
- Diarrhoea, sometimes
- Fever
- Dehydration
Severe cases progress to collapse, shock, systemic inflammation, clotting abnormalities and organ failure. Mortality in severe acute pancreatitis is significant.
Chronic pancreatitis is subtler — intermittent vomiting, occasional inappetence, mild recurring discomfort — and is frequently missed for months.
This is a same-day veterinary visit. Repeated vomiting with abdominal pain always is.
Diagnosis
There is no single perfect test, and diagnosis combines several things:
- Clinical signs and examination
- Specific canine pancreatic lipase (cPL) blood testing, which is the most useful single test
- General bloodwork to assess organ function, electrolytes and inflammation
- Abdominal ultrasound, which can show pancreatic changes and rule out other causes of the same signs — a foreign body, for instance
Ultrasound matters, because obstruction produces a very similar picture and needs entirely different treatment.
Treatment
Supportive, and it works well in most cases.
- Intravenous fluids, which is the mainstay
- Pain relief. Pancreatitis is genuinely very painful, and good analgesia is central rather than optional
- Anti-nausea medication
- Early feeding. The old approach of prolonged fasting has been abandoned — current evidence favours feeding a low-fat diet early, sometimes via a feeding tube, because the gut does better when it is used
- Antibiotics only where there is evidence of infection
- Treating the underlying cause, if identified
Most mild cases recover in a few days. Severe cases need intensive care.
Long-term feeding
This is where owners have real influence, and it matters because dogs who have had pancreatitis once are prone to recurrence.

A low-fat diet, permanently, for most dogs. Your vet will specify a target — often under about 10 percent fat on a dry matter basis, sometimes lower. Veterinary gastrointestinal low-fat diets exist for exactly this.
Absolutely no fatty extras. This is the rule the whole household must understand:
- No table scraps, ever
- No roast fat, bacon, sausage, cheese, butter or cream
- No pig’s ears, bully sticks or fatty chews
- No peanut butter, which is very high in fat
- No leftovers “just this once”
Read the fat content of every treat. Many commercial treats are surprisingly fatty. Safer options: pieces of the dog’s own low-fat food, plain cooked chicken breast with all skin and fat removed, green beans, carrot.
Secure the bins and the worktops. The single most common cause of recurrence is a successful raid.

Useful here for a different reason than usual: a low-fat diet often means a larger volume of food, and slowing the meal down makes it more satisfying without adding anything to it.
Keep them lean. Obesity raises risk independently.
Small, frequent meals rather than one or two large ones.
Review medications with your vet, since a few are associated with pancreatitis.
Christmas, barbecues and holidays
A disproportionate number of cases arrive in the days after a celebration. The specific culprits:
- Turkey skin and roast fat
- Sausages and pigs in blankets
- Cheese boards
- Barbecue trimmings and dropped burgers
- Bin raids after a party
- Well-meaning guests feeding scraps
Tell your guests. One sentence — “please don’t feed the dog anything, he’s had pancreatitis” — prevents the most likely version of the problem.
Miniature Schnauzers specifically
Worth a separate note. The breed is predisposed to hypertriglyceridaemia — persistently high blood fats — which is itself a risk factor for pancreatitis.
If you have a Schnauzer, ask your vet about checking triglyceride levels, particularly after a fasted sample. A low-fat diet from the start is a reasonable precaution in this breed even without a history of an episode.
Prognosis
Most dogs with a single mild episode recover fully and, with sensible feeding, never have another.
Dogs with recurrent or chronic pancreatitis can develop diabetes or exocrine pancreatic insufficiency as the organ is progressively damaged, which is the argument for taking the dietary management seriously rather than relaxing it once they seem well.
