The Grains: Why Barley Comes First
Why does this dog food start with barley and brown rice?
Barley and brown rice provide carbohydrates and fiber that support everyday energy needs and normal digestion. Both are whole grains, and neither is wheat or corn.
These grains can suit healthy adult dogs with typical activity levels. Individual dogs may tolerate ingredients differently, so monitor your dog's response when introducing a new food.
What are ancient grains in dog food?
Ancient grains are grains with long histories of cultivation. This recipe includes grain sorghum and millet, which contribute carbohydrates, fiber, and some protein.
Both grains are naturally gluten-free, but the term ancient grains doesn't automatically make a food more nutritious or suitable for every dog.
Is this dog food grain-free?
No. Maintenance Formula Classic Roast is grain-inclusive and contains no peas, lentils, or chickpeas.
The FDA has investigated reports of canine dilated cardiomyopathy (DCM), a heart condition, involving certain diets, many of which contained substantial amounts of legumes or potatoes. However, the evidence has not established a conclusive cause-and-effect relationship.
Dogs with existing heart conditions or breed-related risk factors should discuss appropriate dietary choices with their veterinarian.
The Protein: Dried Yeast and Potato
Is 23% protein enough for an adult dog?
For many healthy adult dogs, 23% minimum crude protein can be suitable as part of a complete and balanced diet. Individual needs depend on activity, body condition, and health.
Classic Roast guarantees at least 1.5% lysine and 0.4% methionine. More active dogs may need a different nutritional profile, so ask your veterinarian whether a higher-protein recipe, such as Wild Earth's Performance Formula, is appropriate.
What is dried yeast doing fourth on the list?
Dried yeast contributes plant-based protein, amino acids, B vitamins, and savory flavor. Alongside potato protein and other ingredients, it helps supply the amino acids dogs need for everyday body maintenance.
Turmeric and Black Pepper

Is turmeric good for dogs?
Turmeric adds an interesting nutritional element to Classic Roast. It contains curcumin, a plant compound researchers have explored for its potential role in supporting a healthy inflammatory response. In a small study involving dogs with osteoarthritis, dietary curcumin was associated with changes in genes linked to inflammation, highlighting its potential as a complementary area of research for canine joint health. Explore the research on curcumin and inflammatory response in dogs.
Why is black pepper extract in dog food?
Black pepper extract contains piperine, a compound studied for its potential to increase curcumin absorption. Curcumin is poorly absorbed on its own, which is why researchers have investigated this combination.
Black pepper extract is a supporting ingredient in the recipe, not a standalone supplement dose. Its inclusion doesn't make the kibble spicy or establish a therapeutic effect.
Should I add extra turmeric at home?
Don't add turmeric supplements without consulting your veterinarian. Concentrated supplements can cause digestive upset or interact with medications, and their suitability depends on your dog's individual needs.
The Fats: Flaxseed and Plant Oils
Flaxseed supplies alpha-linolenic acid (ALA), an omega-3 fatty acid. Canola, safflower, and sunflower oils contribute dietary fats, including omega-6 fatty acids.
Classic Roast guarantees at least 1.4% omega-6 and 0.7% omega-3 fatty acids. These fats contribute to normal skin and coat function as part of a balanced diet.
Classic Roast doesn't list added DHA. Performance Formula guarantees at least 0.05% DHA for owners looking for a recipe with this omega-3 fatty acid.
Heart Support: Taurine and L-Carnitine
Taurine supports normal heart muscle function, while L-carnitine helps transport fatty acids for energy production.
Classic Roast guarantees at least 0.1% taurine and 75 mg/kg of L-carnitine. Their inclusion doesn't mean the food prevents or treats heart disease. Dogs with cardiac conditions need individualized veterinary guidance.
Vitamins, Minerals, and Preservatives
Classic Roast includes minerals in sulfate and proteinate forms, selenium yeast, and vitamins A, D2, E, and B vitamins.
Mixed tocopherols and rosemary extract help preserve the formula. Vitamin D2 is part of the recipe's vitamin profile.
Both Maintenance Formula flavors are formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for adult maintenance.
Is the Maintenance Formula Hypoallergenic?
The Maintenance Formula is made without several common canine food allergens, including beef, chicken, dairy, eggs, wheat, soy, lamb, pork, rabbit, and fish. It also contains no corn or animal by-products.
However, hypoallergenic doesn't mean every dog will tolerate the food. Dogs can react to different ingredients, including those in plant-based recipes.
If you suspect a food allergy, consult your veterinarian about an elimination diet to help identify the trigger.
Classic Roast or Golden Rotisserie?

Both Maintenance Formula flavors have the same guaranteed analysis and are formulated to meet AAFCO nutritional standards for adult maintenance. Their stated calorie contents per cup differ slightly.
Classic Roast provides 250 calories per cup, while Golden Rotisserie provides 245 calories per cup. Both provide 3,325 kcal/kg.
Check the current packaging for flavor-specific ingredient information when choosing between the two.
Who Is Maintenance Formula Dog Food Best For?
Maintenance Formula is designed for adult dogs that need complete and balanced everyday nutrition. Its plant-based formulation may also suit owners looking to avoid common ingredients such as beef, chicken, or dairy.
At 250 calories per cup, Classic Roast may fit a calorie-controlled feeding plan, but portion size and total daily calorie intake still matter. This recipe is intended for adult maintenance, not puppy growth.
When changing foods, transition gradually over seven to ten days and monitor your dog's appetite, stool, and overall response.
Final Takeaway
Wild Earth Maintenance Formula Classic Roast combines whole grains, plant-based proteins, plant oils, vitamins, and minerals for everyday adult nutrition.
And what about the black pepper? Its extract contains piperine, which researchers have studied for its role in curcumin absorption. It's a supporting ingredient, not a promise of a therapeutic effect.
Explore Wild Earth Maintenance Formula to review the ingredients and nutritional information for your adult dog's everyday diet.
Frequently Asked Questions

It can take several weeks for symptoms to improve after removing the offending ingredient. Veterinary elimination diets often last eight weeks or longer, depending on the case. Follow your veterinarian's instructions throughout the trial.
Is turmeric safe for dogs?
Turmeric in formulated dog food differs from a concentrated supplement. Ask your veterinarian before adding turmeric or curcumin products, particularly if your dog takes medication or has an existing health condition.

The best choice depends on whether the skin problem comes from food, environmental allergens, parasites, or another cause. A veterinarian can help identify the cause and determine whether a dietary trial is appropriate.
