If your dog regularly struggles with gas, loose stools, or an upset stomach, the problem may not be just what they eat—but how well they digest it. The best dog foods with digestive enzymes are designed to help break down proteins, fats, and carbohydrates so nutrients can be absorbed more efficiently. For dogs with sensitive digestion, certain dietary needs, or recurring tummy troubles, choosing a food that supports digestive function can make mealtimes easier on their system. However, not every formula that mentions digestive enzymes offers the same nutritional quality, ingredient standards, or overall benefits. Knowing what to look for can help you avoid unnecessary fillers while choosing a complete, balanced diet that supports both digestion and everyday health. In this guide, we’ll break down the best dog foods with digestive enzymes, what makes them different, key ingredients to prioritize, and how to choose the right option for your dog.

Latest Research on Digestive Enzymes in Dog Food

According to the latest research, digestive enzymes may improve the digestibility of certain nutrients in dog food, but results vary depending on the enzyme, diet, and individual dog.

📄 Research Update — Digestive Enzymes

Digestive Enzyme Benefits Are Not Guaranteed in Healthy Dogs

In a controlled study of healthy adult dogs, adding plant- or animal-derived digestive enzyme supplements to a commercial dry diet did not significantly improve energy or macronutrient digestibility. The findings suggest that healthy dogs eating an already digestible, complete diet may not automatically benefit from additional digestive enzymes.[1]

📊 Clinical Focus — Protease Supplementation

Protease May Improve Protein Digestibility in Some Dog Foods

A 2024 crossover study in adult Beagles found that adding a microbial protease to an extruded diet increased apparent digestibility of both dry matter and crude protein compared with the control diet. The enzyme did not significantly change fat or ash digestibility, highlighting that benefits may depend on the specific enzyme and nutrient being targeted.[2]

⚠️ Research Context — Enzyme Blends

Laboratory Research Shows Promise, but In-Vivo Results Still Matter Most

A simulated canine digestion study found that a multi-enzyme blend increased dry matter digestibility, digestible energy, and the release of several nutrients from dry dog food. However, because the experiment was performed in vitro rather than in live dogs, the findings show potential rather than proving that every enzyme-containing food will provide the same digestive benefits in practice.[3]

How Foods with Digestive Enzymes Help Dogs

Digestive enzymes help break food into smaller components the body can process during digestion. Different enzymes target specific nutrients, including proteins, fats, carbohydrates, and certain plant-based ingredients.

Enzyme or Feature How It Helps What It Targets
Protease Helps break large proteins into smaller peptides and amino acids. Meat, fish, eggs, and other protein ingredients.
Lipase Helps split dietary fats into smaller components for absorption. Animal fats, fish oils, and other dietary fats.
Amylase Helps break starch into simpler carbohydrates during digestion. Rice, oats, potatoes, peas, and other starches.
Cellulase Helps break down certain plant cell-wall fibers dogs cannot digest on their own. Vegetables and plant-based ingredients.
Multi-enzyme blends Target several food components at once instead of relying on one enzyme. Mixed diets containing protein, fat, starch, and plant ingredients.
Enzymes added after processing May help preserve enzyme activity that can otherwise be reduced by high-heat processing. Extruded kibble and other heat-processed foods.

Remember to ALWAYS consult with your vet before making any changes that could affect your dog’s health, nutrition, or well-being. If you can’t reach your vet, you can chat live with a registered online veterinary professional via our online vet chat or video chat support (24 hours a day, 7 days a week). Or use Chewy’s online vet services (6 a.m. – midnight ET). Additionally, at-home dog gut health tests can analyze your dog’s microbiome, offering insights into which nutrients their diet should include. Similarly, at-home dog allergy testing kits can identify ingredients that may not be suitable for your dog, enabling you to choose the right diet and care plan to support optimal digestion, nutrition, and health.

What sets it apart from competitors: The Pets Table personalizes daily portions using individual factors such as a dog’s age, weight, and activity level rather than relying solely on generic package feeding amounts. Its Mixed Plan can also divide daily calories between Fresh and Air-Dried meals in a 50/50 split, giving owners two food formats within one coordinated feeding program.

Other Dog Foods With Digestive Enzymes

  • Best Dog Food for Picky Eaters With Digestive Enzymes: ZIWI Peak Air-Dried Dog Food earns this spot because its meat-rich, air-dried texture and aroma are especially appealing when a dog routinely loses interest in ordinary kibble. Its core air-dried recipes contain up to 96% meat, organs, seafood, and bone, while many also incorporate cold-washed green tripe, which ZIWI specifically identifies as highly palatable and supportive of digestion and sensitive stomachs. Gentle Z-TWINTECH air-drying circulates warm air rather than using conventional kibble extrusion, helping protect the nutritional characteristics of its raw ingredients. Green tripe also provides naturally occurring digestive components and probiotics, while the concentrated animal ingredients deliver plenty of aroma and flavor without relying on artificial palatants. That combination of palatability, nutrient density, and digestive-friendly ingredients makes ZIWI especially useful when getting a selective dog interested in mealtime is the first challenge.
  • Best Budget Dog Food With Digestive Enzymes: Sojos Complete Freeze Dried Raw Adult Dry Dog Food is a practical value pick because its lightweight dry concentrate expands substantially once water is added—a 7-pound package can make up to 40 pounds of prepared food. The recipes combine gently freeze-dried raw meat with air-dried fruits and vegetables, keeping preparation simple while avoiding the need to store large quantities of frozen raw food. Sojos specifically instructs soaking the food for about 15 minutes to rehydrate it and “activate” its nutrients and enzymes before serving. Ingredients such as pumpkin, papaya, vegetables, seeds, and animal proteins create a varied whole-food nutritional profile, while the Complete recipes are formulated for adult maintenance. Its concentrated format, long shelf life, and substantial prepared yield are what make it a sensible budget-oriented route into enzyme-containing raw-style feeding.
  • Best Dog Food With Digestive Enzymes and Probiotics: Nextrition Cold-Pressed Food for Dogs stands out for taking a broader microbiome approach instead of relying on probiotics alone. Every recipe combines chicory-root prebiotics, five live probiotic strains, yeast-derived postbiotics, and natural fiber from pumpkin and sweet potato, giving beneficial gut microbes both direct cultures and fermentable nutritional support. Its lower-temperature cold-pressing process is designed to preserve naturally occurring enzymes and live cultures that can be damaged during conventional high-heat extrusion. Each recipe also starts with real meat and avoids corn, wheat, soy, artificial colors, flavors, and preservatives. Because it brings enzymes, prebiotics, probiotics, postbiotics, and whole-food fiber together in one complete all-life-stages diet, Nextrition is the most targeted choice here for dogs whose feeding plan prioritizes comprehensive digestive and microbiome support.

How to Transition Your Dog to a New Diet with Digestive Enzymes

Switching gradually gives your dog’s digestive system time to adjust and helps reduce the chance of stomach upset. The schedule below offers a simple 7–10 day transition, but sensitive dogs may need a slower change.

Transition Stage Old Food New Food What to Do
Days 1–2 75% 25% Mix thoroughly and keep portions consistent.
Days 3–4 50% 50% Continue if digestion remains comfortable.
Days 5–6 25% 75% Increase the new food gradually.
Day 7+ 0% 100% Feed the new diet as the regular meal.
Sensitive Dogs Reduce more slowly Increase more slowly Extend the transition to 10–14 days if needed.

Monitoring Your Dog’s Progress on a New Diet with Digestive Enzymes

After the transition, watch how your dog responds over the next few weeks. Pay attention to appetite, stool quality, vomiting, energy level, and whether any digestive symptoms become less frequent, stay the same, or worsen.

Also track body weight and overall condition, especially if your dog previously had poor digestion or difficulty maintaining weight. Contact your veterinarian if vomiting or diarrhea persists, appetite drops, weight changes unexpectedly, or symptoms become more severe.

Dogs with ongoing gastrointestinal disease, pancreatic conditions, or other medical concerns should have diet changes and progress monitored with veterinary guidance.

Frequently Asked Questions

Digestive enzymes may help when diarrhea is related to poor digestion, but they are not a general treatment for diarrhea because infections, parasites, food intolerances, and gastrointestinal diseases can cause similar symptoms. Persistent or worsening diarrhea should be evaluated by a veterinarian.

It may help some dogs if poorly digested food contributes to excess fermentation and gas. However, frequent or severe gas can also result from diet intolerance, rapid eating, or gastrointestinal disease, so enzymes are not always the solution.

Digestive-enzyme foods are not intended to treat recurrent vomiting. Occasional mild stomach upset may improve after an appropriate dietary change, but repeated vomiting warrants veterinary evaluation to identify the underlying cause.

They can be useful for some older dogs with specific digestive disorders, but age alone does not mean a dog needs extra enzymes. Senior dogs should primarily receive a nutritionally complete diet suited to their health, body condition, and individual digestive needs.

Digestive enzymes such as protease, lipase, and amylase help break down protein, fat, and carbohydrates. Probiotics are beneficial microorganisms intended to support the intestinal microbial community, so the two serve different digestive functions and may appear together in some foods.

A complete and balanced dog food containing added digestive enzymes can generally be fed as the dog’s regular diet when it is appropriate for their life stage and health needs. This is different from concentrated enzyme supplements, which may require veterinary guidance depending on why they are being used.

The Bottom Line

Choosing the best dog foods with digestive enzymes starts with finding a nutritionally complete diet that suits your dog’s age, health, and digestive needs. Enzymes such as protease, lipase, and amylase help break down different components of food, although their benefits can vary among dogs and formulas. Research suggests certain enzyme additions may improve the digestion of specific nutrients, but healthy dogs do not always gain measurable benefits from supplementation. The overall quality, digestibility, and nutritional balance of the food remain just as important as the presence of added enzymes. Transitioning gradually and monitoring stool quality, appetite, energy, and weight can help you determine how well a new food agrees with your dog. Ultimately, the right formula should provide balanced daily nutrition while supporting comfortable, consistent digestion.
