Pancreatitis in Dogs: Causes, Symptoms, and Treatment

Pancreatitis is a condition in which the pancreas becomes inflamed, causing a disruption in its normal functions. The pancreas, located just under the stomach and along the duodenum, plays a crucial role in digestion and insulin regulation. When pancreatitis occurs, the digestive enzymes stored in the pancreas are prematurely activated and start digesting the body’s own tissues, leading to a cascade of complications.

The Normal Pancreas and Its Functions

When we eat food, it goes through a process of digestion. The stomach breaks down the food further with the help of enzymes, and eventually, the small intestine absorbs the nutrients. The pancreas, as a glandular organ, secretes digestive enzymes to aid in the breakdown of nutrients. It also produces insulin and glucagon to regulate the use of these nutrients. However, in pancreatitis, the focus is on the disruption of the pancreas’ ability to produce digestive enzymes.

Causes and Risk Factors

Pancreatitis in dogs can have various causes and risk factors. Some possible causes include:

  • Backwash of duodenal contents into the pancreatic duct
  • Concurrent hormonal imbalances such as diabetes mellitus, hypothyroidism, and hypercalcemia
  • Use of certain drugs like sulfa-containing antibiotics, chemotherapy agents, and organophosphate insecticides
  • Trauma to the pancreas from accidents or surgical manipulation
  • Tumors in the pancreas
  • Consumption of a high-fat meal
  • Obesity, particularly in Miniature Schnauzers

Symptoms and Diagnosis

The symptoms of pancreatitis in dogs may include appetite loss, vomiting, diarrhea, a painful abdomen, fever, or a combination of these. To diagnose pancreatitis, veterinarians may rely on blood tests to measure the levels of amylase and lipase, two pancreatic digestive enzymes. However, these tests are not always reliable and can be affected by other factors. A newer test called the pancreatic lipase immunoreactivity (PLI) test has shown promise in diagnosing pancreatitis more accurately. Imaging techniques like radiographs and ultrasound can also aid in the diagnosis.

Treatment and Management

The treatment of pancreatitis in dogs primarily focuses on aggressive rehydration through intravenous fluids to restore circulation to the pancreas and support the body’s natural healing mechanisms. Hospitalization is often necessary during the initial stages of treatment. Pain and nausea medication are administered to keep the patient comfortable and improve their appetite. Plasma transfusion, though controversial, may be used to replenish blood proteins that have been consumed by digestive enzymes.

Nutritional support is also crucial in the management of pancreatitis. Contrary to previous beliefs, early return to feeding has been found to be beneficial for the gastrointestinal tract’s function. Low-fat diets are essential and should be continued for several weeks before attempting a return to regular dog food. It is important to determine the fat content of pet food accurately by considering the moisture content and calculating the fat content based on dry matter. In case of doubt, alternatives like canned chicken, fat-free cottage cheese, and boiled white rice can be used.


Pancreatitis in dogs can be a painful and life-threatening condition. It is essential to recognize the symptoms and seek prompt veterinary care for an accurate diagnosis and appropriate treatment. With proper management, including hydration, pain control, and a low-fat diet, dogs with pancreatitis have a better chance of recovery.
