What is Wild Earth?

Wild Earth aims to make dog food better using plant-based formulas.

The company was founded by a group of dog owners disappointed in the modern dog food industry. They found the dog food industry had an unhealthy dependency on meat, and this dependency was leading to harmful ingredients, bad practices, and bad health.

To help, Wild Earth decided to make a new, better type of dog food using plant-based ingredients. The company developed dog food made from high-quality, cruelty-free ingredients using sustainable sources that are better for the planet.

Today, you can buy three types of dog products from Wild Earth, including dog food (like the popular Performance Formula and Maintenance Formula), dog supplements (for joints, energy, digestion, and more), and dog treats (available in multiple natural flavors).

What Makes Wild Earth Unique?

You have plenty of options for dog food. Why pick Wild Earth? What makes Wild Earth unique compared to other companies?

Some of the benefits and unique features of Wild Earth include:

Plant-Based Ingredients: Most traditional dog foods use meat and other animal-based ingredients for nutrition. Wild Earth takes a different approach, using exclusively plant-based ingredients to deliver similar nutritional value. Instead of animal fats, for example, Wild Earth uses healthy fats from flaxseed and sunflower oil to give your dog the omega-3 and omega-6 fatty acids it needs.

Made by Veterinarians & Animal Food Scientists: The Wild Earth team consists of veterinarians and animal food scientists, giving the dog food company additional certified legitimacy over other companies available online today.

Potential Health Benefits for Dogs: According to the official Wild Earth website, many dog owners have reported significant benefits after switching to Wild Earth. Wild Earth’s reported benefits include more energy, fewer allergies, a shinier coat, better digestion, a healthier weight, and more.

Happiness Guarantee: Wild Earth offers a “Happiness Guarantee” refund policy. If you or your dog are unhappy with Wild Earth within 30 days of receiving your order, then you can request a refund.

Cruelty-Free Ingredients: Wild Earth exclusively uses cruelty-free ingredients in its supplements.

Vet-Developed for Better Health: Wild Earth’s dog foods and treats were developed by vets and animal food scientists to improve your pet’s health.

Sustainable Practices: Wild Earth emphasizes sustainable practices for better pets and a healthier planet. The company uses sustainable ingredients in its dog foods and treats.

Clean Plant Protein: Wild Earth uses dried yeast as its “plant-based protein powerhouse,” according to the official website. That dried yeast provides the amino acids your dog needs to thrive and build strong muscles without animal-derived ingredients. In comparison, many dog foods contain cheap, animal-based sources of protein.

Plant-Based, Fiber-Rich Complex Carbs: Wild Earth dog foods and treats are made from complex carbs – like sweet potatoes. These complex carbs can provide healthy energy while being high in fiber. Your dog needs fiber to promote healthy digestion and regular bowel movements.

Healthy Plant-Based Fats: Instead of using animal fats in its dog foods and treats, Wild Earth uses a variety of plant-based fats, including flaxseed oil and sunflower oil. Your dog can get the omega-3 and omega-6 fatty acids it needs for optimal skin and coat health – all without relying on cheap and unhealthy animal fats.

Subscribe to Save 30%: You can subscribe to one or more Wild Earth products to receive regular shipments, then save 30% off your purchase. Instead of spending $99 on a large bag of Performance Formula dog food from Wild Earth, you can spend just $69.

Dried Yeast for High-Quality Protein: The backbone of many Wild Earth foods and treats is dried yeast, which contains 49% protein by weight. In comparison, beef contains just 24% protein. Dried yeast is also very sustainable, and you can grow yeast in just three days with fewer resources required. Dried yeast is an ideal source of protein because it contains all ten essential amino acids your dog needs while also being rich in beta-glucans, B vitamins, and other nutrients for digestive health.

Avoid Allergies & Contaminants in Meat: Many traditional dog foods use animal meat for protein. Although high-quality animal meat dog foods are available, many dog foods contain cheap meats associated with allergens and toxic contamination. Wild Earth takes a different approach.

86% of Customers Report a Noticeable Improvement in Dogs After Switching to Wild Earth: According to the official Wild Earth website, 86% of the company’s customers have reported health improvements after switching to Wild Earth, including relief from allergies, greater energy, shinier coats, and more.

Featured on Shark Tank: Wild Earth founder Ryan Bethencourt appeared on Shark Tank in episode 1013. Ryan was seeking a $550,000 investment for 5% equity, and he left the show with a $550,000 investment for 10% equity from Mark Cuban – despite the fact his company had no sales to justify its $11 million valuation at the time it appeared.

Superfoods, Plants, & Herbs for Immune Support: Many Wild Earth foods and treats contain superfoods, plant extracts, and herbs to promote overall health. For example, the Wild Earth Performance Formula contains spinach, blueberries, and other fruits and vegetables. Other products are rich with antioxidants to promote coat and fur health, a healthy immune system, and other benefits.

Wild Earth Products

Wild Earth Products

Wild Earth separates its products into three categories, including:

We’ll break down each category and the products within that category below.


Wild Earth is America’s most popular plant-based dog food. The company makes dog food from superfoods and plant-based ingredients to support your dog’s overall health. You can choose from two formulas, including the Performance Formula or Maintenance Formula.

Performance Formula

Wild Earth’s Performance Formula dog food is available in a single flavor: veggie chick’n kabob. The dog food contains clean, vegan ingredients designed to provide balanced nutrition – including the vitamins, minerals, and omega-3 and omega-6 fatty acids your dog needs.

Key Performance Formula dog food ingredients include muscle-supporting protein, prebiotic fiber for digestion, and healthy fats. Wild Earth developed the formula based on AAFCO standards, adding more protein and supplemental nutrients and enhancing flavor.

The Performance Formula features 28% protein by weight and is formulated for all adult dogs across all breeds. It’s ideal for dogs with active to very active lifestyles.

Price: $39 (small 4lb bag) to $99 (large 18lb bag)

Maintenance Formula

Available in two flavors (Classic Roast or Golden Rotisserie), Wild Earth’s Maintenance Formula features clean ingredients and a science-backed blend of ancient grains and healthy fiber to support your dog’s overall health. It’s a vegan dog food designed to give your dog everything it needs: delicious kibble.

Each serving of the Wild Earth Maintenance Formula contains a minimum of 23% crude protein and 9% crude fat, along with a maximum of 5% crude fiber and 10% moisture. The dog food also contains lysine, methionine, calcium, phosphorus, sodium, omega-3, and omega-6 fatty acids to support your dog’s overall health.

The Wild Earth Maintenance Formula is formulated for all adult dogs of all breeds, although it’s ideal for dogs with less active to active lifestyles.

The most significant ingredients in the Wild Earth Maintenance Formula include barley, brown rice, grain sorghum, dried yeast, potato protein, millet, canola oil, and sweet potato.

Price: $69 (small 12.5lb bag) to $125 (large 28lb bag)


Wild Earth offers a lineup of daily health supplements for dogs, including skin and coat supplements, hip and joint supplements, immunity and digestion supplements, and more. Instead of giving your dog multiple supplements daily, you can give your dog a single supplement for each health concern.

Available Wild Earth dog supplements include:

Skin & Coat Dog Supplements

Wild Earth’s Skin & Coat supplements are available for small dogs (under 25 lbs), medium dogs (25 to 75 lbs), and large dogs (over 75 lbs). They come in a single flavor: peanut butter.

Each supplement contains a blend of plant-powered ingredients to make your dog’s coat softer and their skin healthier from the inside. You can give your dog a combination of omega fatty acids and oils linked to skin and coat health. Some of the ingredients soothe sensitive skin, while others soften skin and smooth fur.

Active ingredients in Wild Earth’s Skin & Coat supplement include algae (DHAgold) for omega-3 and omega-6 fatty acids, evening primrose oil, vitamin E, vitamin C, astaxanthin, and zinc. Wild Earth has mixed these active ingredients with flaxseed, natural flavors (oregano, flaxseed, and plums), palm fruit oil, pea fiber, and peanut butter to make a delicious treat any dog will love.

Price: $30

Hip & Joint Dog Supplements

Wild Earth’s Hip & Joint dog supplements feature a blend of plant-based ingredients to support your dog’s mobility and help relieve joint pain. Many of the ingredients are natural anti-inflammatories rich with antioxidants linked to joint pain relief. The supplement also contains omega fatty acids.

Wild Earth’s Hip & Joint supplements contain glucosamine, organic turmeric, algae (DHAgold), curcuminoid extract, and hyaluronic acid. Many of these are the same ingredients in human joint pain relief supplements.

Wild Earth’s Hip & Joint supplement aims to help your dog run and play all day. Wild Earth uses natural flavors like oregano, flaxseed, plum, and peanut butter to make it a tasty treat for your dog.

Price: $30

Immunity & Digestion Dog Supplements

Wild Earth’s Immunity & Digestion supplement uses a blend of organic mushrooms, digestive enzymes, and probiotics to support your dog’s immune system and digestion.

Like humans, dogs have a significant portion of their immune system in their gut. You could support your dog’s immunity by supporting gut health and digestion.

Active ingredients in Wild Earth’s Immunity & Digestion formula include organic mushrooms (including reishi, cordyceps, chaga, lion’s mane, turkey tail, maitake, shiitake, blazei, agarikon, oyster, and true tinder mushroom extract), fructooligosaccharides (as prebiotic fiber), digestive enzymes (like amylase, protease, lipase, cellulose, papain, bromelain, and hemicellulase), beta-glucans, and probiotics.

Wild Earth has mixed these active ingredients with a similar blend as found in the other two supplements, including oregano flaxseed, plum, and peanut butter flavor, to make it palatable for any dog.

Price: $30

Wild Earth Treats

Wild Earth sells a popular lineup of dog treats in three flavors: peanut butter, strawberry, and beet, and banana and cinnamon. You can reward your pet without guilt, giving them an irresistible treat without harmful additives.

Wild Earth’s treats are vet-developed with clean ingredients and designed to be low in calories. One of the most important unique ingredients in each treat is koji, which comes from fermented soybeans or rice. Wild Earth uses koji to provide dogs with a nutrient-rich blend of plant-based nutrition.

  • Peanut Butter: $30
  • Strawberry & Beet: $30
  • Banana & Cinnamon: $30
  • 3 Flavor Variety Pack: $30

How to Switch to Wild Earth Dog Food

Wild Earth recommends switching your dog to plant-based dog food gradually. Instead of replacing all ordinary dog food with Wild Earth’s Performance Formula or Maintenance Formula at once, you should mix it into your dog’s diet over a one-week transition.

Here’s how Wild Earth recommends making the switch:

  • Days 1 to 2: Mix 25% Wild Earth dog food into 75% of your dog’s old food per meal for a 25/75 split.
  • Days 3 to 4: Mix 50% Wild Earth dog food into 50% of your dog’s old food per meal for a 50/50 split.
  • Days 5 to 6: Mix 75% Wild Earth dog food into 25% of your dog’s old food per meal for a 75/25 split.
  • Days 7+: Complete the transition by filling 100% of your dog’s bowl with Wild Earth dog food.

Scientific Evidence for Wild Earth: Does Vegan Dog Food Good for Dogs?

Wild Earth’s website is filled with stories of dog owners improving their dog’s health and increasing longevity using the company’s plant-powered products. But is there any science supporting these claims? Can you switch to plant-based ingredients to help your dog? We’ll review some of the scientific evidence below.

In a 2023 study performed by the University of Illinois’s Department of Animal Sciences, a team tested two human-grade vegan dog food formulas against a leading chicken-based dog food. They fed the diets to beagles for three weeks, then sampled the dogs’ blood, tested their fecal quality, and checked their gut microbiome. Here’s what they found:

Researchers praised the vegan dog food for containing a nutritionist-formulated mix of whole foods like lentils, chickpeas, sweet potatoes, squash, apples, blueberries, and more.

The vegan and chicken-based dog foods met the standards set by the Association of American Feed Control Officials (AAFCO) for “complete and balanced” dog nutrition.

The vegan dog food was highly digestible while generating stool similar to the chicken-based dog food, suggesting both dog foods helped the dogs stay regular.

Researchers found dogs fed vegan dog food had significantly lower blood triglyceride and cholesterol levels (measures of circulating fats) than those fed chicken-based dog food.

Researchers also analyzed the fecal microbiome and noticed a surprising change in the vegan dog food group. Researchers found dogs in the vegan diet group had lower levels of fecal metabolites phenol and indole, both of which contribute to fecal odor. All dog poop will stink, but dog poop from dogs in the vegan food group smelled significantly less.

Overall, researchers praised vegan dog food for being easy to digest, providing valuable nutrients, and causing positive changes to the gut microbiome, blood cholesterol, and triglyceride levels.

In another recent study, researchers analyzed the effects of vegan and vegetarian diets on a group of cats and dogs. Researchers reviewed 16 trials on pet food and veganism, concluding there were few significant negative side effects of switching to a vegan or vegetarian diet, assuming the pet’s nutritional needs were met.

Eating a vegan diet could help your dog live longer. A 2022 study found 49% of dogs eating conventional meat suffered from health disorders, compared to just 43% of dogs eating raw meat and 36% eating vegan food. Because of these results, researchers concluded that “the healthiest and least hazardous dietary choices for dogs are nutritionally sound vegan diets.”

Overall, we need more research to verify vegan and vegetarian diets are healthy for dogs conclusively. However, early evidence is promising. Assuming you’re meeting your dog’s nutritional needs (as is the case with Wild Earth dog food, which exceeds AAFCO standards), you could help your dog live longer and improve health biomarkers using vegan and vegetarian dog food.
