Pancreatitis in dogs
Inflammation of the pancreas, often triggered by a fatty meal, causing vomiting and severe abdominal pain.

AI-generated illustrative health cover; it does not depict a specific patient or diagnosis.

Signs to watch for
- Repeated vomiting
- Abdominal pain — hunched back or 'praying' posture
- Loss of appetite
- Diarrhoea
- Lethargy
- Fever
Causes and risk factors
Often follows fatty food or scavenging; obesity, some medications and hormonal disease raise risk. Many cases have no clear trigger.
How veterinarians diagnose it
Examination, blood tests including a pancreas-specific lipase test, and abdominal ultrasound.
Treatment and management
Supportive hospital care: fluids, pain relief, anti-sickness medication and early careful feeding of a low-fat diet.
Prevention
Avoid fatty table scraps, keep dogs lean and secure bins. Dogs with past episodes often stay on a low-fat diet.
Outlook
Mild cases recover well; severe cases can be life-threatening and some dogs have recurrent episodes.

Pancreatitis: feeding decisions that matter
| Situation | Next step |
|---|---|
| Vomiting, hunched posture or belly pain | See a vet promptly; do not offer rich food or human painkillers. |
| Discharge after an episode | Feed the prescribed low-fat diet in small, frequent meals. |
| Treats and extras | Choose lean options within the daily ration; ask the vet first. |
| Prevention at home | No fatty scraps; secure bins; keep the dog lean. |
| Signs return after recovery | Phone the clinic the same day; repeats are common in prone dogs. |
Repeated vomiting with belly pain is not a home-care case. Human painkillers can poison dogs.
Severe tummy pain after rich food is a vet visit, not a wait-and-see
Pancreatitis is inflammation of the pancreas, and in dogs it often follows a fatty meal, scavenging or rich table scraps, though many cases have no clear trigger. Signs range from repeated vomiting, a hunched or praying posture and obvious belly pain to lethargy and refusing food. Mild-looking signs can still mask a serious episode, so a dog that vomits more than once, seems painful or goes off food should be examined rather than watched at home for days.
There is no safe home remedy. Do not offer rich food to tempt a nauseated dog, and do not give human painkillers, which are dangerous to dogs. At the clinic, examination and tests assess severity and rule out other causes; treatment centres on fluids, pain relief, anti-nausea medication and careful reintroduction of food. Honest cost and intensity conversations with the team help you choose realistic care.
Recovery and prevention are mostly about the bowl
After an episode, most dogs go home on a low-fat diet with small, frequent meals, and many need that feeding approach permanently. Follow the discharge instructions on what and how much to feed, and introduce any diet change gradually over days. Keep treats lean and count them within the daily ration; ask the vet which treats are acceptable rather than guessing.
The reliable prevention is unglamorous: no fatty scraps, secure bins and counters against scavenging, and keeping the dog at a healthy weight. Warn visitors and children that feeding the dog is off-limits. Some dogs, including certain terriers, are prone to repeat episodes, so ask your vet whether your dog's breed, age or history changes the plan. A single further bout of vomiting or pain after recovery deserves a phone call, not a wait.
Other conditions and medicines to mention
Tell the veterinarian about any diabetes, hormonal disease, recent medicines or scavenging episodes, because these can influence risk and management. Dogs with previous pancreatitis may need a review before major diet changes, new treats or holiday boarding. Give carers written feeding rules.

Preparing for a pancreatitis in dogs consultation
- Record when these signs began and how they changed: Repeated vomiting; Abdominal pain — hunched back or 'praying' posture; Loss of appetite. Record appetite, water intake, toileting and any medicines or supplements.
- The listed urgency is urgent; worsening breathing, collapse, seizures or severe pain can make any situation an emergency. Ask the clinic rather than relying only on this category.
- Ask what else could explain the signs, which tests would change the plan and how discomfort will be managed. Symptoms alone cannot confirm this condition.
- Before going home, agree what to monitor, when to recheck and which signs mean calling sooner. Follow the individual treatment plan; do not copy another pet's prescription.
