Watching your German Shepherd struggle with loose stools, weight loss, and poor coat condition despite a hearty appetite is heartbreaking. When your dog has Exocrine Pancreatic Insufficiency (EPI), every meal becomes a careful calculation because their body simply cannot break down and absorb nutrients the way it should. The right diet changes everything, and I have spent months digging through nutritional research and real owner stories to find what truly works for this challenging condition.
I’m Mo Mahin — the founder and writer behind Furric. I analyze veterinary nutritional guidelines and evaluate real owner feedback from hundreds of EPI support groups to identify diets that support digestive health in breeds predisposed to pancreatic conditions.

How To Choose The Best Dog Food For EPI German Shepherd
Feeding a German Shepherd with EPI is not like feeding a healthy dog. Their pancreas produces little to no digestive enzymes, which means food must be highly digestible, low in fiber, and carefully balanced in fat and protein. Here are the three most important factors to evaluate before making a purchase.
Digestibility and Fiber Content
Dogs with EPI cannot handle high-fiber diets because fiber interferes with enzyme activity and slows nutrient absorption. Look for foods with moderate to low crude fiber — ideally under 4 percent. Ingredients like pumpkin, beet pulp, and chicory root offer gentle prebiotic support without overwhelming the digestive tract. Avoid foods loaded with peas, lentils, and legume concentrates, as these are harder for an EPI dog to break down.
Fat and Protein Balance
EPI dogs need moderate fat levels — not too high, not too low. Fat is a dense energy source that helps with weight gain, but too much can trigger diarrhea if enzyme coverage is incomplete. Aim for 12 to 18 percent fat on a dry matter basis. Protein should come from high-quality, easily digestible sources such as chicken, lamb, salmon, or beef. Novel proteins can also help if your dog develops food sensitivities alongside EPI.
Ingredient Quality and Additives
Avoid artificial preservatives, colors, and flavors. EPI dogs already have compromised digestion, so every ingredient needs to pull its weight. Look for added probiotics, prebiotics, omega-3 fatty acids, and medium-chain triglycerides (MCTs) which provide quick energy without requiring pancreatic enzymes for absorption. Also confirm the food is formulated to meet AAFCO standards for all life stages so you know the nutrient profile is complete.

In-Depth Reviews
1. Hill’s Prescription Diet Gastrointestinal Biome
Hill’s Prescription Diet Gastrointestinal Biome is the food that EPI owners in support groups mention over and over again. It is specifically formulated to support digestive health using ActivBiome+ ingredient technology, which rapidly activates beneficial gut bacteria and supports a healthy GI microbiome balance. The chicken and vegetable stew format is palatable even for picky dogs, and the wet texture makes it easier to mix with pancreatic enzymes.
What sets this formula apart is the precise balance of soluble and insoluble fibers that promote regular bowel movements without overloading the digestive tract. It also contains high levels of omega-3 fatty acids (DHA and EPA) to support skin and coat health, which is often compromised in EPI dogs. One longtime owner shared that after struggling with loose stools for years, this was the first food that gave their dog consistently solid poop. Another noted that their 16-year-old dog no longer needed anal gland expression after switching. A Shihtzu owner reported that their picky eater finally cleaned her bowl and stopped having gut flare-ups.
For a German Shepherd with EPI, this is the closest thing to a guaranteed win. It requires a veterinary prescription, but the clinical results speak for themselves. If you want the most research-backed, GI-specific option on the market, start here.
Why we love it
- Clinically proven ActivBiome+ technology supports gut health
- Optimal fiber balance promotes firm, regular stools
- High omega-3 fatty acids improve skin and coat condition
- Wet food format mixes easily with enzyme supplements
Good to know
- Requires veterinary prescription
- Higher daily cost compared to standard kibble
- Limited flavor options available
2. Wysong Epigen 90 Starch Free Formula
Wysong Epigen 90 is unlike any other kibble on the market because it is completely starch-free. That is a huge deal for EPI dogs, because starch requires pancreatic amylase to break down, and EPI dogs simply do not produce enough of that enzyme. This formula gets as close as possible to what a canine’s ancestral diet looks like, with unprecedented meat content including organic sources.
The recipe is packed with probiotics, prebiotics, enzymes, phytonutrients, and natural-form antioxidants — everything a compromised digestive system needs to function better. It also delivers rich omega-3 fatty acids and essential fatty acids for coat and joint support. Because the kibble is very nutrient dense, the feeding guidelines recommend introducing it slowly and using smaller portions than typical foods. Many owners use it as a protein booster or meal supplement alongside a base diet.
If your German Shepherd has severe EPI and struggles to digest standard kibble, this starch-free approach can be a genuine breakthrough. It is manufactured by Wysong in their own facility under strict quality control protocols. This is a premium tool in the EPI management toolbox, not a casual food switch.
Why we love it
- Completely starch-free, ideal for pancreatic insufficiency
- Extremely high meat content with organic sources
- Rich in probiotics, prebiotics, and digestive enzymes
- Nutrient dense so dogs eat less volume
Good to know
- Must be introduced very slowly to avoid GI upset
- Higher price point than standard kibble
- Not a complete standalone diet for all dogs
3. ZIWI Peak Steam & Dried Beef with Pumpkin
ZIWI Peak uses a unique Steam & Dried process that locks in the nutritional benefits of fresh raw ingredients while providing the shelf stability of dry food. This is a single-protein formula featuring grass-fed beef from New Zealand, raised without artificial hormones under strict welfare standards. For EPI dogs that may also have food sensitivities, a single-protein limited-ingredient diet can make a world of difference.
The addition of pumpkin, beets, carrots, and chicory root provides natural prebiotic fiber that supports digestive health without being harsh on the gut. The recipe is grain-free, low carb, and high in animal protein, which aligns well with what EPI dogs need for steady energy and weight maintenance. The soft but crunchy texture is approachable for dogs with dental sensitivities or those who struggle with hard kibble. It can be served as a complete meal or used as a topper to boost nutrition.
For EPI German Shepherd owners who want the cleanest ingredient panel possible and are willing to invest in premium sourcing, ZIWI is an outstanding choice. The ethical sourcing and careful processing give you confidence that every bite supports your dog’s recovery.

4. Open Farm Ancient Grains Salmon Recipe
Open Farm’s Ancient Grains recipe with wild-caught salmon is a strong contender for EPI dogs that tolerate grains well. The formula uses oats and quinoa as gentle carbohydrate sources that provide steady energy without spiking blood sugar or irritating the digestive tract. The salmon is wild-caught and traceable to its geographic origin, which matters when you are feeding a dog with a compromised system.
This recipe is specifically recommended for sensitive stomachs and avoids peas, potatoes, and legumes — ingredients that can be problematic for EPI dogs. It delivers 90 percent animal protein mixed with non-GMO fruits, vegetables, and superfoods like pumpkin and coconut oil. The fiber profile is moderate and comes from whole food sources rather than concentrated fiber isolates. Every ingredient is third-party certified and can be traced through their website.
For the EPI German Shepherd owner who wants transparency and whole-food ingredients without a prescription diet, Open Farm delivers. The ancient grains provide digestible carbohydrates that work well with enzyme therapy, and the omega-rich salmon supports coat health during recovery.

5. ORIJEN Amazing Grains Original Recipe
ORIJEN Amazing Grains brings the brand’s signature high-protein philosophy into a grain-inclusive format that works better for EPI dogs than their grain-free line. The formula contains 90 percent animal ingredients including poultry and organs, following ORIJEN’s WholePrey approach to deliver the most nutrient-rich parts of the prey. The first five ingredients are fresh or raw poultry and fish, providing a strong foundation of bioavailable protein.
The grains included are sourced from non-GMO crops and provide moderate fiber that supports stool quality without overwhelming enzyme activity. Freeze-dried coating on the kibble adds a burst of raw flavor that encourages picky eaters to clean their bowl. The recipe supports three key health areas: digestive health, immune support, and healthy skin and coat. It is formulated for all life stages except growth of large-size puppies over 70 pounds.
For EPI German Shepherds that need high-quality protein to rebuild muscle mass and condition, ORIJEN delivers in a big way. The grain inclusion makes it more digestible for EPI dogs compared to ultra-high-protein grain-free options, and the nutrient density means your dog gets more from each serving.

6. Farmina N&D Pumpkin Grain-Free Lamb & Blueberry
Farmina’s Natural & Delicious line with pumpkin and blueberry offers a grain-free alternative that still prioritizes digestive comfort. The lamb protein is a novel option for German Shepherds that may have developed sensitivities to chicken or beef after months of dietary trial and error. Pumpkin is the star ingredient here, providing gentle soluble fiber that helps firm up loose stools without causing constipation.
The formula uses Farmina’s vacuum coating system that preserves the longevity of vitamins and nutrients, ensuring your dog gets the full benefit of every antioxidant and omega fatty acid in the bag. It is formulated for adult dogs of medium breeds, but the nutrient profile works well for large-breed EPI dogs when fed according to weight guidelines. The absence of added sugar and the inclusion of blueberries as a natural antioxidant source add extra immune support.
If your EPI German Shepherd needs a grain-free diet due to grain sensitivities, this pumpkin-infused recipe from Farmina is a thoughtful choice. The lamb and blueberry combination is gentle on the stomach while still delivering complete and balanced nutrition.

7. Eagle Pack Natural Dry Large Breed Dog Food
Eagle Pack Natural Dry Large Breed formula is the most budget-conscious option on this list, but that does not mean it cuts corners where it counts. This recipe is made by the same company that produces Wellness, a highly respected premium brand, and the ingredient list reflects that shared quality. It features optimal protein, fat, and carbohydrate levels specifically balanced for large breed dogs, which aligns well with the German Shepherd’s build.
The formula includes glucosamine for joint support, omega fatty acids for skin and coat health, and antioxidants for immune function. It contains no corn, wheat, meat by-products, artificial colors, flavors, or preservatives. The kibble size is larger, which encourages chewing and slower eating — a bonus for deep-chested breeds prone to bloat. One Greyhound owner reported that both their dogs adapted well and maintained healthy stools after switching to Eagle Pack.
For EPI German Shepherd owners working within a tighter budget, Eagle Pack offers reliable large-breed nutrition without the prescription price tag. It is not as specialized as the top picks, but it provides a clean, balanced foundation that can work well alongside enzyme therapy.
Why we love it
- Large breed specific nutrient balance
- Glucosamine for joint health in big dogs
- No corn, wheat, or artificial additives
- Manufactured by same company as Wellness
Good to know
- Not specifically formulated for EPI or GI issues

- Some dogs find the kibble too large
Safety & Care Tips
Proper Feeding Schedule
Feed your EPI German Shepherd three to four smaller meals per day rather than one or two large portions. Smaller meals are easier for the compromised pancreas to handle and improve the effectiveness of enzyme replacement therapy. Allow your dog to eat without rushing, and avoid strenuous exercise for at least one hour after meals to reduce the risk of bloating and digestive upset.
Enzyme Supplementation Integration
Always mix pancreatic enzymes with the food and let it sit for 15 to 20 minutes before serving. This pre-incubation step allows the enzymes to begin breaking down the food before it even enters your dog’s stomach. Never sprinkle enzymes directly on top of dry kibble without moisture, and avoid cooking or microwaving enzymes as heat destroys their activity. Monitor stool quality daily and adjust enzyme dosage in consultation with your veterinarian.
