Most high-protein dog foods start with meat. Wild Earth Performance Formula starts with dried yeast. That might sound unusual, but dogs need specific nutrients, not a particular protein source.

This plant-based recipe provides 28% minimum crude protein and 346 kcal per cup. It combines dried yeast, potato protein, grains, plant oils, marine microalgae, and essential nutrients in a formula designed for adult maintenance.

Here's a closer look at the ingredients, what they contribute, and which dogs may be suited to this recipe.

What Is in Wild Earth Performance Formula Dog Food?

Wild Earth Performance Formula ingredient list with notes on dried yeast, grains, potato protein, microalgae and taurine

The Performance Formula gets protein from dried yeast and potato protein, carbohydrates and fiber from grains and sweet potato, and fats from plant oils, flaxseed, and marine microalgae. Added vitamins, minerals, and functional ingredients help complete the recipe.

Ingredients appear in descending order by weight, so the first few ingredients offer a useful starting point when evaluating a dog food.

Role Ingredients What they do
Protein Dried yeast, potato protein Supply amino acids for muscle maintenance and repair
Energy and fiber Barley, oats, grain sorghum, millet, sweet potato Provide carbohydrates, fiber, and additional protein
Fats and omegas Canola oil, flaxseed, sunflower oil, safflower oil, marine microalgae Supply energy and essential fatty acids, including DHA
Heart and muscle Taurine, L-carnitine Support normal physiological functions
Gut support Inulin from chicory root, fructooligosaccharide (FOS) Provide prebiotic fibers
Fruit and vegetables Blueberries, cranberries, pumpkin, spinach Contribute plant compounds
Vitamins, minerals, and preservatives Proteinate minerals, vitamins, mixed tocopherols, rosemary extract Help meet nutritional needs and protect fats from oxidation

The Protein: Why Yeast Comes First

What Is Dried Yeast in Dog Food?

Dried yeast is inactive yeast that has been grown and dried. It won't ferment or make dough rise. It provides protein and can contribute B vitamins and savory flavor.

Where Does the Rest of the Protein Come From?

Potato protein is concentrated protein extracted from potatoes. Barley, oats, grain sorghum, and millet also contribute protein, helping the recipe reach its guaranteed minimum of 28% crude protein.

How Does a Plant-Based Recipe Cover Amino Acids?

Dogs need essential amino acids, regardless of whether they come from animal or plant ingredients. Performance Formula guarantees at least 1.9% lysine and 0.5% methionine. Combining different protein sources helps provide a broader amino acid profile.

The Carbs: Grains for Everyday Energy

Why Barley, Oats, Sorghum, and Millet?

These grains provide carbohydrates for energy, along with fiber and additional protein. Oats and barley also contain beta-glucans, a type of soluble fiber.

For dogs that run, hike, train, or stay active throughout the day, carbohydrates contribute to the energy they need for movement.

Is Performance Formula Grain-Free?

No. Performance Formula is grain-inclusive and legume-free, with no peas, lentils, or chickpeas.

The FDA has investigated reports of canine dilated cardiomyopathy (DCM), a disease affecting the heart muscle, in dogs eating certain diets. Some reported diets contained substantial amounts of legumes or potatoes. The FDA describes the potential association between diet and DCM as complex and has not established a definitive cause.

Read the FDA's investigation update and the Veterinary Information Network's report on diet-related heart problems.

Taurine and L-carnitine are included in this recipe, but their presence does not establish that a diet prevents DCM. If your dog has a heart condition or belongs to a breed predisposed to heart disease, ask your veterinarian about appropriate dietary choices.

The Fats: Where the Omega-3s Come From

What Do Flaxseed and Plant Oils Add?

Flaxseed provides alpha-linolenic acid (ALA), an omega-3 fatty acid. Canola, sunflower, and safflower oils contribute fatty acids, including omega-6s, that help support normal skin and coat function.

The formula guarantees at least 1.7% omega-6 and 0.8% omega-3 fatty acids. Mixed tocopherols help preserve the oils.

How Does a Plant-Based Dog Food Get DHA Without Fish?

Marine microalgae supplies DHA directly, without fish ingredients. Dogs have a limited ability to convert ALA into DHA, so a direct dietary source can help supply this omega-3 fatty acid.

Performance Formula guarantees at least 0.05% DHA, which plays a role in normal brain and eye function.

The Heart and Muscle Add-Ins

Why Is Taurine Added to Dog Food?

Taurine supports normal heart function and other physiological processes. Although most dogs can produce taurine themselves, dietary formulation and individual needs still matter. Performance Formula guarantees at least 0.1% taurine.

What Does L-Carnitine Do for Active Dogs?

L-carnitine helps transport fatty acids into mitochondria, where cells can use them for energy. Heart and skeletal muscles rely on this process. The formula guarantees at least 75 mg/kg of L-carnitine.

The Gut Support: Inulin and FOS

Four bowls showing how to switch dog food over 7 to 10 days: 25%, 50%, 75%, then 100% new food

Inulin from chicory root and FOS are prebiotic fibers that help feed beneficial gut bacteria. Some dogs experience temporary digestive changes when switching foods.

Introduce the new food gradually over 7 to 10 days, following the product's transition guidance. Increase the proportion of new food from 25% to 50%, then 75%, and finally 100%. Contact your veterinarian if digestive symptoms persist or become severe.

The Fruit and Vegetables: Small Amounts, Honestly

Blueberries, cranberries, pumpkin, and spinach appear toward the end of the ingredient list, so they contribute relatively small amounts by weight. They're additional plant ingredients, not the recipe's primary sources of protein or calories. Most of the formula's nutrition comes from its main ingredients and added nutrients.

Vitamins, Minerals, and Preservatives

What Are Proteinate Minerals in Dog Food?

Proteinate minerals are minerals bound to amino acids or related organic compounds. Their absorption varies by mineral and formulation. Performance Formula guarantees at least 150 mg/kg of zinc, which supports normal physiological functions, including skin health.

Why Vitamin D2 Instead of D3?

Vitamin D2 is a non-animal-derived form of vitamin D. Vitamin D helps regulate calcium and phosphorus balance and supports normal bone health.

How Is the Food Preserved?

Mixed tocopherols and rosemary extract help protect fats from oxidation. The recipe does not list artificial preservatives, colors, or flavors.

Which Ingredients Does Performance Formula Leave Out?

Performance Formula contains no beef, dairy, chicken, wheat, lamb, pork, egg, soy, rabbit, or fish. It also contains no corn, legumes, or animal by-products.

However, dogs can react to many ingredients, including grains and yeast. If you suspect a food allergy, consult your veterinarian before changing diets or starting an elimination trial.

Who Is Performance Formula Dog Food Best For?

Performance Formula has 28% minimum protein and 346 kcal per cup, made for active adult dogs, not puppies

Performance Formula is designed for adult dogs, including working and sporting dogs, whose activity levels and calorie needs suit this recipe. It may also suit lean adult dogs that struggle to maintain weight.

The formula is intended for adult maintenance, not puppies. Less-active dogs or dogs that need fewer calories may be better suited to Wild Earth's Maintenance Formula Classic Roast, which provides 250 kcal per cup.

Older dogs losing muscle need an individualized assessment. Ask your veterinarian whether a higher-protein or higher-calorie diet is appropriate, particularly if an underlying health condition is involved.

Final Takeaway

Dried yeast, potato protein, and grains form the protein foundation of Performance Formula. Plant oils and flaxseed contribute essential fatty acids, while marine microalgae supplies DHA. Taurine and L-carnitine round out the recipe.

The right food depends on your dog's age, activity level, health, and nutritional needs. Review the ingredient list and guaranteed analysis, and consult your veterinarian if your dog has specific dietary concerns.

Frequently Asked Questions

Is Vegan Dog Food Good for Dogs?

A properly formulated, nutritionally complete vegan diet can meet an adult dog's nutritional needs. Suitability depends on the recipe, its nutrient balance, and the individual dog's health.

Is Plant-Based Dog Food Better Than Meat-Based?

Neither is automatically better. Nutritional adequacy, digestibility, and your dog's individual needs matter more than protein source alone.

Is Plant-Based Dog Food Nutritionally Complete?

It can be. Choose a food formulated to meet recognized nutritional standards for your dog's life stage and consult your veterinarian about individual requirements.

Is High-Protein Dog Food Good for Active Dogs?

Adequate protein supports muscle maintenance and repair. Active dogs also need sufficient calories, fat, and other essential nutrients, so protein percentage alone doesn't determine whether a food is suitable.

Does Vegan Food Help Dog Skin Allergies?

A plant-based food that excludes a dog's specific trigger may help manage a diagnosed food allergy. Vegan food does not automatically prevent or treat allergies. Veterinary guidance is important.

What Is in Wild Earth Dog Food?

The Performance Formula contains dried yeast, potato protein, grains, plant oils, flaxseed, marine microalgae, vitamins, minerals, and other functional ingredients.

Is Wild Earth Dog Food Safe?

Performance Formula is formulated for adult maintenance. Whether it's appropriate for an individual dog depends on the dog's health and nutritional needs. Consult your veterinarian before changing diets, especially if your dog has a medical condition.
