Exocrine Pancreatic Insufficiency in Dogs

Ashley Bates

When we bring our pups home for the first time, it’s hard to imagine all of the things that could potentially go wrong. As an owner, you want your dog to be fit, healthy, and issue-free. But sometimes, your dog might start to display symptoms that make you uneasy.

If your dog has experienced pancreatic problems in the past, you might want to learn about exocrine pancreatic insufficiency. It may be time to make an appointment so your vet can examine your best buddy if they have a few existing symptoms.


What Is the Function of the Pancreas?

The pancreas is a V-shaped organ that sits near the stomach and small intestine. The pancreas makes juices filled with enzymes that serve different aspects of digestion.

It has two main functions called endocrine and exocrine. Endocrine functions release hormones into the bloodstream. The exocrine function produces enzymes to break down proteins, fats, and carbohydrates for digestion.

If something happens to decrease the exocrine function of the pancreas, it can cause a whirlwind of symptoms for your pooch.

What Is Exocrine Pancreatic Insufficiency in Dogs?

Exocrine pancreatic insufficiency, or EPI, in dogs happens when the body cannot produce the enzymes necessary to break down fats, proteins, or carbs they consume. Because of decreased function, it leads to symptomatic problems like steatorrhea—which is fat in the stool.

If your dog has EPI, their body cannot retain valuable nutrients from their daily diet. It can lead to malabsorption, deficiencies, and weight loss.

What Causes Exocrine Pancreatic Insufficiency in Dogs?

Exocrine pancreatic insufficiency can be something your dog is born with, otherwise called a congenital condition. It can also develop later as a genetic condition in the bloodline. But any dog can get EPI if they get an infection or have an injury to their pancreas—like chronic pancreatitis.

EPI generally affects dogs that are middle-aged and older but is not breed-specific.


What Are the Symptoms of Exocrine Pancreatic Insufficiency?

You might not notice any alarming symptoms of EPI until it is pretty advanced. Early detection is critical for proper treatment—so the earlier you pick up on cues, the better.

The noticeable symptoms of EPI include:
  • Pale, greasy, or fatty stools
  • Increase in waste
  • Polyphagia
  • Weight loss
  • Increased appetite
  • Possible vomiting

Only your vet can determine if your dog has EPI, but it’s time to get them in for evaluation if they display any of these symptoms.

How Is Exocrine Pancreatic Insufficiency Diagnosed?

Your vet will perform blood or fecal tests to determine if EPI is present in the body. If the results show positive results, they will evaluate a further plan of care.

How is Exocrine Pancreatic Insufficiency Treated?

It will involve dietary changes and enzyme replacements to aid your dog’s digestive process to treat EPI. Many vets recommend a diet that has incredibly digestible nutrients and very little fat. Usually, dogs require some enzyme replacement to amp up their digestive functionality.

Depending on the root cause of EPI, your dog might also require an antibiotic. This condition shouldn’t decrease the lifespan or restrict the habits of your pooch. Don’t make any treatment decisions or dietary changes without the guidance of your vet.

Can You Prevent Exocrine Pancreatic Insufficiency?

Since symptoms of this condition don’t appear until the disease is well underway, it’s impossible to prevent EPI. However, you can manage the symptoms with proper medical advice from a licensed veterinarian.

Is Exocrine Pancreatic Insufficiency Curable?

EPI is curable in some circumstances, but it depends on the underlying issue. If it develops due to a medical ailment called chronic pancreatitis, it will usually resolve itself as the condition is treated and the pancreas regains functionality.

But sometimes, this condition develops because of a genetic malfunction—in which case, it isn’t curable—only manageable by diet and supplementary changes.

Tips to Help Your Dog Through Endocrine Pancreatic Insufficiency

Even though you can’t reverse EPI, you can still help your pup along the way. It might take behavioral or habitual adjustments, but it’s worth the change.

Avoid feeding human food or table scraps

Your dog won’t need anything in its system that is hard to digest. Avoid anything outside of their strict diet, no matter how much those pleading eyes beg otherwise.

Feed your dog on a strict schedule

Your vet will recommend the amount and frequency when it comes to mealtime. Portions and recipes will vary depending on the condition your dog is in.

Keep up with supplements at all times

Many dogs will require digestive supplements to regulate and improve digestion. Since their pancreas has an issue breaking down the starches and fats, supplements will smooth the process.

Take your dog for regularly scheduled checkups

Because of EPI, your dog might have more frequent vet visits. It’s important to keep up with all scheduled dates to ensure your dog is on par and healthy.


Final Thoughts

If you suspect that your dog might have EPI, it’s best to get them to the vet for further evaluation. If your pet had a recent diagnosis and you’re trying to educate yourself, remember that dietary changes are the most important adjustments you can make for your pooch.

Working alongside your veterinarian will help you make good decisions in treatment. Dogs with EPI can still live normal lives as long as you address the issue proactively.
