Pancreatitis in Pets: Signs, Treatment and Prevention

Pancreatitis is a painful condition that can affect both dogs and cats. It occurs when the pancreas becomes inflamed, potentially causing significant discomfort and making your pet feel very unwell. While some cases are mild, others can be severe and require hospitalisation.

Recognising the signs early and seeking veterinary care can make an important difference to your pet’s recovery.

What is pancreatitis?

The pancreas is a small organ located near the stomach and small intestine. It plays two important roles in the body: producing digestive enzymes that help break down food and producing hormones, including insulin, which regulates blood sugar levels.

Pancreatitis occurs when the pancreas becomes inflamed. Digestive enzymes that would normally become active in the intestine can activate prematurely, damaging pancreatic tissue and surrounding structures.

The condition can develop suddenly, known as acute pancreatitis, or persist over time as chronic pancreatitis. Some pets may experience repeated episodes, while others develop a single, severe bout of illness.

What causes pancreatitis in pets?

In many cases, the exact cause of pancreatitis is unknown. However, several factors may increase the risk, including:

• Fatty foods: In dogs, eating rich, fatty foods or table scraps can trigger an episode. Leftover roast meats, fatty trimmings and food scraps may be particularly problematic for susceptible pets.

• Dietary indiscretion: Eating rubbish, spoiled food or unfamiliar foods may contribute to digestive upset and, in some cases, pancreatitis.

• Underlying health conditions: Certain metabolic disorders and other illnesses may increase the risk.

• Medications and other factors: Some medications or exposures may be associated with pancreatitis, although this varies and a direct cause is not always established.

• Individual susceptibility: Some pets may be more prone to developing the condition due to their genetics, age or overall health.

Cats can also develop pancreatitis, but their cases are often less clearly linked to dietary fat. The cause may remain unknown, and other illnesses can occur alongside the condition.

Signs of pancreatitis to watch for

The symptoms of pancreatitis can vary considerably. Some pets develop obvious signs of illness, while others show only subtle changes in behaviour or appetite.

Common signs in dogs

Watch for:

• Vomiting or repeated retching

• Loss of appetite

• Abdominal pain or discomfort

• A hunched posture or reluctance to move

• Lethargy or unusual tiredness

• Diarrhoea

• Dehydration

• Fever in some cases

Some dogs may adopt a characteristic posture with their front legs stretched forward and their hindquarters raised, sometimes called the “prayer position”. This can indicate abdominal pain, although it is not specific to pancreatitis.

Signs in cats

Cats can be particularly difficult to assess because their symptoms may be subtle. Signs can include:

• Reduced appetite or refusing food

• Lethargy and hiding more than usual

• Vomiting, although this is less common than in dogs

• Weight loss

• Dehydration

• Abdominal discomfort

• Changes in normal behaviour

If your cat stops eating or seems unusually quiet, do not assume they are simply being fussy. Cats can become seriously unwell when they go without adequate food, so prompt veterinary advice is important.

When should you seek veterinary care?

Contact our vets promptly if your pet develops vomiting, abdominal pain, reduced appetite or unusual lethargy. Seek urgent veterinary attention if your pet has repeated vomiting, severe pain, marked weakness, collapse or cannot keep water down.

Pancreatitis can resemble other illnesses, so it is important not to rely on symptoms alone.

How is pancreatitis diagnosed?

There is no single sign that confirms pancreatitis. Our vets will assess your pet's symptoms, medical history and physical examination findings before recommending appropriate tests.

Depending on the situation, investigations may include:

• Blood tests: These can help assess hydration, inflammation, organ function and other possible causes of illness.

• Pancreatic-specific blood tests: Specialised tests can help identify inflammation of the pancreas in dogs and cats.

• Ultrasound: Abdominal imaging may reveal changes around the pancreas and help identify other conditions.

• Additional investigations: Further tests may be recommended to assess complications or rule out other causes of vomiting and abdominal pain.

A diagnosis is usually made by combining the clinical findings with test results. Not every pet will require every test.

How is pancreatitis treated?

Treatment depends on the severity of the condition, your pet's symptoms and whether complications are present. There is no single medication that cures every case of pancreatitis. The aim is to support the body while the inflammation settles and to manage pain, nausea and other problems.

Treatment may include:

1. Fluid therapy

Pets with pancreatitis may become dehydrated through vomiting, reduced drinking and fluid losses. Fluids given under the skin or intravenously can help correct dehydration and maintain circulation, depending on the severity of the illness.

2. Pain relief

Pancreatitis can be painful, even when your pet does not show obvious signs of discomfort. Appropriate veterinary pain relief is an important part of treatment.

3. Medication for nausea and vomiting

Anti-nausea medication can help control vomiting and improve your pet's comfort. Our vets may also recommend other medications depending on the individual case.

4. Nutritional support

Maintaining nutrition is an important part of recovery. Once vomiting and nausea are controlled, early feeding is generally preferred over prolonged fasting. Our vets may recommend small, frequent meals or a specific diet that is easy to digest.

Dogs with pancreatitis are often prescribed a low-fat diet, particularly if dietary fat is considered a contributing factor. Cats may need a different nutritional approach, as restricting fat is not routinely recommended for every cat with pancreatitis.

If a pet will not eat enough independently, additional nutritional support may be needed.

5. Hospitalisation and monitoring

Severe cases may require hospital care for intravenous fluids, pain relief, nutritional support and close monitoring. Complications can include significant dehydration, systemic inflammation and problems affecting other organs.

Antibiotics are not routinely required for uncomplicated pancreatitis. They may be used if there is evidence of a bacterial infection or another specific indication.

Recovery time varies. Some pets improve within a few days, while others need longer treatment and ongoing dietary management.

Can pancreatitis be prevented?

Unfortunately, pancreatitis cannot always be prevented, particularly when the underlying cause is unknown. However, there are practical steps you can take to reduce some risk factors.

Avoid fatty table scraps

One of the most useful precautions for dogs is to avoid feeding fatty leftovers, meat trimmings, greasy foods and rich treats. Even if your dog has tolerated these foods in the past, they may still cause problems.

Choose an appropriate diet

Feed a complete and balanced diet suited to your pet's species, age and health needs. If your pet has previously experienced pancreatitis, ask our vets whether a prescription or specially formulated diet is appropriate.

Keep rubbish and food scraps secure

Prevent pets from accessing rubbish bins, compost, discarded food and unattended meals. Be particularly careful around barbecues and family gatherings, when tempting scraps may be within easy reach.

Maintain a healthy weight

Keeping your pet at a healthy weight supports their overall health and helps reduce the risk of several other conditions. Our vets can advise on an appropriate feeding plan and exercise routine.

Manage underlying health conditions

Follow our vets’ advice for managing any existing medical conditions and discuss any concerns about medications. Never stop prescribed medication without veterinary guidance.

Act early if symptoms develop

Prompt veterinary assessment can help identify pancreatitis and other serious illnesses before complications become more severe.

What if my pet has had pancreatitis before?

Some pets recover completely after one episode, while others may experience recurrent or chronic inflammation. Our vets may recommend ongoing dietary adjustments, regular monitoring and a plan for recognising early warning signs.

If your pet has a history of pancreatitis, avoid experimenting with rich foods or treats without checking whether they are suitable. It is also worth discussing what to do if vomiting, reduced appetite or lethargy returns.

For cats, maintaining adequate food intake is especially important. If your cat has a history of pancreatitis and begins eating less, seek veterinary advice rather than waiting for other symptoms to appear.

The bottom line

Pancreatitis can be a serious and painful condition, but prompt veterinary care and appropriate supportive treatment can help many pets recover.

Avoiding fatty table scraps, providing a suitable diet and watching for changes in appetite or behaviour are sensible steps towards protecting your pet's health.

If you are concerned that your dog or cat may have pancreatitis, contact our veterinary team for advice. We can assess your pet, investigate the cause of their symptoms and recommend the most appropriate treatment and ongoing care.
