Exocrine pancreatic insufficiency (EPI) is a disease that severely impacts the pancreas’ ability to produce digestive enzymes. EPI can be a problematic condition for your canine to deal with, and it can be difficult for you as the dog owner to help them through it. Along with replacing digestive enzymes and vitamin B12 injections, a special diet can improve your dog’s digestion. Firmer stools and more nutrients absorbed into your dog’s system are the goal.
The ideal diet is calorie-dense, digestible, and low in fiber. More calories mean less volume needs to go through your dog’s digestive tract, which improves digestion. The ideal dietary fat content is a matter of some debate and depends on the individual dog. You should ask a vet their opinion but it may take some trial and error to find what works for your dog.
But which option should you choose? This article aims to present several reviews to help you make a well-informed decision about which dog food will best suit your German Shepherd. So, let’s take a look!
Disclaimer: The foods reviewed here were chosen because they have certain characteristics that might help with some of the causes or consequences of this medical condition. However, they are not a medical treatment or a substitute for medical treatment. Keep in mind that each medical case is different and what works for some pets may not work for others. A veterinarian is the right person to advise you on the best diet for your pet’s individual case.

Buyer’s Guide: How to Pick the Best Dog Foods for EPI German Shepherds
After reading the reviews, picking an option for your dog may still feel overwhelming. So, where do you start?
What Should a Dog With EPI Eat?
As with most pet recommendations, the best thing you can do is speak to a vet. They will have personalized insight into your dog’s particular needs and will be best able to help you form a dietary plan for your pup.
However, some general guidelines may help you decide what you can and cannot feed your German Shepherd.
Highly digestible food is generally a huge help for dogs, and anything that is low in fiber can prove useful, too. The maximum fiber content is around 5%, but less can be better. Fiber interferes with fat digestion. However, not all fiber is created equal. Crude fiber is listed on the feed analysis but doesn’t tell you if the diet is soluble or insoluble, with soluble fibers being preferred.
The ideal fat content will vary from dog to dog. Is your German Shepherd overweight and prone to pancreatitis? They may be suited to a low-fat diet. Are they skinny and in need of weight gain? Then a moderate amount of fat is better.
Pick a diet suited for your dog’s age. If they have any other health problems or food intolerances, you might find a suitable diet to cater to them. Of course, every dog is different. That is why it is important to speak with a vet to learn how to best provide for your pet.
If you need to speak with a vet but can't get to one, head over to PangoVet. It's an online service where you can talk to a vet online and get the personalized advice you need for your pet — all at an affordable price!
Does My Dog Need Enzyme Supplements?
Yes. Digestive enzymes are necessary for your dog’s feeding routine since the body isn’t producing enough enzymes on its own. The supplements must be added to each meal. They are available in tablets and powders, but the powders are known to be the most effective.
Take a look at this enzyme product to see if it’s suitable for your canine.
How to Feed My Dog Enzyme Supplements
Pay attention to the instructions on the bottle and the instructions offered by your vet. Beyond that, it is helpful to mix the powder into the meal as much as possible. This is important since your dog may shy away from eating what they believe is a strange powder, or their mouth could be irritated by the supplement if it is too concentrated in one spot.
Over time, as the symptoms begin to lessen, it is advised that you gradually decrease the number of supplements you are mixing into each meal. Although your dog will not be able to go entirely off the enzymes, the idea is to wean your dog down to a smaller portion.
