Pancreatitis in Dogs: Signs, Treatment, and Prevention

What causes it

In most dogs, vets cannot find one clear cause. Several things have been linked to a higher risk.

• Eating fatty food, such as table scraps, roast skin, fat trimmings or greasy leftovers
• Getting into the trash
• Being overweight
• High levels of fat in the blood
• Hormone diseases, such as Cushing's disease, an underactive thyroid or diabetes
• Some medicines
• Severe injury, or surgery and anesthesia
• Certain infections, including babesiosis and leishmaniasis

Some breeds are affected more often. Miniature Schnauzers are affected far more than other breeds, and a genetic link is suspected. Yorkshire Terriers, Cocker Spaniels, Dachshunds, Poodles and sled dogs also appear more often. Any dog can develop pancreatitis, though.

A single large, fatty meal can be enough to set off an attack. Vets tend to see more cases around holidays and family celebrations, when leftovers are easy to reach and guests share food from the table.

Pancreatitis is not contagious. A dog with pancreatitis cannot pass it to other dogs, cats or people. If two dogs in the same home fall ill at the same time, the cause may be something they both ate or another illness they share. Both dogs should see the vet.

Signs to watch for

Signs depend on how severe the attack is. Mild cases can be vague, and some dogs show almost nothing. Common signs include the following.

• Vomiting, often more than once
• Loss of appetite
• Belly pain, so your dog may flinch when touched or resist being picked up
• A hunched back, or the "prayer position," with the front legs and chest down on the floor and the rear end up
• Diarrhea
• Tiredness and weakness
• Dehydration
• Fever

The prayer position can look like a play bow. A dog in pain tends to hold it for longer and seems uncomfortable. Many dogs take this position to ease pain in the belly.

Belly pain is easy to miss. Vets assume that a dog with pancreatitis is in pain, even when the pain is hard to see.

When it is an emergency

It is best to call your vet the same day if your dog vomits more than once, refuses food, or seems painful or unusually tired. Emergency care is recommended right away if your dog keeps vomiting, cannot keep water down, collapses, has pale gums or seems very weak.

Severe pancreatitis can cause shock and failure of other organs, and it can be fatal. Prompt treatment gives a dog a better chance. Vomiting and belly pain also have many other causes, including a swallowed object that blocks the gut, so a vet check matters.

Tell the vet if your dog may have eaten something fatty or raided the trash, even if it happened a day or two earlier. It also helps to bring the names of any medicines your dog takes.

How vets diagnose it

There is no single simple test. The vet puts together your dog's history, a physical exam and the results of several tests.

Routine blood tests show dehydration, signs of inflammation and how other organs such as the liver and kidneys are coping. A specific blood test measures pancreatic lipase, an enzyme made by the pancreas that rises in the blood when the organ is inflamed. It is the most specific blood test for pancreatitis. Many clinics can run a quick version on site and send a more detailed version to a lab.

An ultrasound scan of the belly can show an inflamed pancreas and fluid around it. It can also miss some cases, especially long-lasting ones. X-rays help rule out other problems, such as a swallowed object. In a few dogs, a small tissue sample is needed to be sure.

How it is treated

Treatment supports the body while the inflammation settles. The plan depends on how sick the dog is.

Dogs with a mild attack can often be treated as outpatients. They go home with medicine from the vet for nausea and pain, and small meals of a low-fat, easily digestible food. Dogs with a severe attack usually need to stay in hospital, often for several days. There they receive fluids into a vein to correct dehydration, medicine to control vomiting, and pain relief. Very sick dogs may need a feeding tube or more intensive care.

Advice on feeding has changed. Vets used to keep dogs with pancreatitis off food for several days. Current guidance favors starting food early, once vomiting is under control, and early feeding is now seen as part of recovery. Food is usually held back only while vomiting cannot be controlled. Your vet will tell you when to start and what to feed.

Antibiotics are not given routinely, because pancreatitis is usually not caused by bacteria. Your vet will decide whether your dog needs them.

Most dogs with a mild attack recover well. The outlook after a severe attack is less certain and depends on how the body responds to treatment.

Recovery and long-term care

Some dogs have a single episode. Others have repeat attacks, which vets call chronic or recurring pancreatitis. Repeated inflammation can scar the pancreas over time.

Two long-term problems can follow. One is diabetes, when the pancreas no longer makes enough insulin. Signs include drinking and urinating more and losing weight. The other is exocrine pancreatic insufficiency, when the pancreas no longer makes enough digestive enzymes. Signs include weight loss despite a good appetite and large, pale, greasy stools. Tell your vet if you notice any of these.

After an attack, many vets recommend a low-fat diet and low-fat treats over the long term. This is especially common for dogs that have had more than one episode or belong to a high-risk breed. Ask your vet which food suits your dog.

How to lower the risk

Pancreatitis cannot always be prevented, since many cases have no clear cause. A few simple habits lower the risk.

Keep fatty human food away from your dog, including roast skin, fat trimmings, sausages, bacon, butter and gravy. A trash can with a secure lid helps. During holidays and parties, ask guests not to feed your dog, and clear plates and leftovers quickly.

A healthy weight also helps. Choose low-fat treats, and feed measured meals instead of snacks from the table. If your dog belongs to a high-risk breed or has had pancreatitis before, ask your vet about a low-fat food and regular checkups.

Rescued and newly adopted dogs

The first weeks in a new home bring many changes, and new families often want to spoil a dog with treats. Rich food from the table is one of the easiest risks to avoid. Ask what your dog was eating before adoption, and switch to any new food slowly over several days.

At Paw Squadron, the first stops after every rescue are the vet and a bath. Each animal gets a checkup, deworming and treatment against fleas and other parasites. Before adoption, every animal also gets vaccinations and a microchip. A health check cannot predict pancreatitis, so the everyday habits above matter in every home.

Most Paw Squadron rescues happen in the Balkans. Babesiosis occurs in many parts of Europe, and leishmaniasis is common around the Mediterranean. Both infections have been linked to pancreatitis in some dogs. Tell your vet where your dog came from, since it helps them choose the right tests.
