Our Riverstone Kitchen:
Where Heart + Science comes to life

We are proud control freaks. After years of searching for a facility that could meet our standards, we realized no existing plant ever would. So we created our own.

What is Riverstone?

Riverstone is our own manufacturing facility, built in the farmlands of Maryland specifically to produce Wisdom Air-Dried Food and Jerky to our own exacting standards. From ingredient arrival to finished bag, every batch is a direct expression of what we believe Wisdom should be: exceptional nutrition, crafted with Heart + Science.


*Note: Wisdom Cat Homestyle Paté is made at Naturpak, a specialist co-manufacturing facility. This page covers our Riverstone operation only.

Uncompromising standards

In 2021, Riverstone earned SQF Edition 9 certification for Pet Food Manufacturing, one of the most rigorous food safety standards in the world. Certification matters, but it's the starting point, not the finish line. 

Our food safety program follows the Food Safety Modernization Act and goes further. We've created systems that ensure consistency, traceability, and safety at every step, because you deserve to know exactly what you’re giving to your companion animal. 

How we keep food safe

Separation of raw and finished goods

Specialized water and airflow systems eliminate contamination risk at source

Complete traceability

Every ingredient tracked from arrival through finished product with full lot documentation

Test and hold

No product ships until negative microbial test results are confirmed by third-party labs

Published results

Salmonella testing results for every lot are available on our website

We have always focused on producing high quality and healthy food—now it's validated by SQF certification. Pet parents can be assured their companion animals are getting high quality and healthy food consistently

Gentle process, exceptional nutrition

Most pet food is made with high-heat extrusion: an efficient process that gets food onto shelves quickly but degrades the nutrients, enzymes, and natural flavors that make real food worth eating in the first place.

Wisdom is different. Our proprietary air-drying technique removes moisture slowly at low temperatures, protecting the nutrients, bioavailability, and natural flavor that high-heat processing destroys. The result is food that stays tender and moist, that dogs find genuinely irresistible, and that their digestive systems can actually use.

Why Air-Drying Matters

High Bioavailability

Nutrients stay intact and easier for your animal to absorb

Less Digestive Stress

Gentle processing means easier digestion

Real flavor preserved

Dogs love it because it tastes like real food (because it is!)

Nutrient Integrity

Vitamins, minerals, and Omega-3s retained from farm to bowl

Dr. Bob Goldstein

In our kitchen, we keep a variety of Wisdom flavors on hand for our dog, Jack. Having multiple options maintains his level of interest and prevents boredom. It's one of the happiest times of his day.

— Dr. Bob GoldsteinCo-founder

Every ingredient chosen with purpose.

No fillers. No unnecessary digestive stress. Each ingredient chosen to support gut-first nutrition and contribute to the whole. Together they work like a symphony: distinct components in balance, creating nourishment that's genuinely greater than the sum of its parts.

  • Exceptional Quality Proteins
    Exceptional Quality Proteins

    Including muscle and organs from high-welfare sources, G.A.P.-certified chicken and turkey, free-range grass-fed beef, and MSC-certified wild-caught fish. Chosen for digestibility, nutrient density, and responsible sourcing, not just for the number it puts on a panel.

  • Purposeful Nutrition
    Purposeful Nutrition

    Organic sprouted seeds, functional vegetables, and whole food fiber sources. Every plant ingredient has a job: supporting digestion, providing bioavailable micronutrients, or contributing to the gut health that underpins everything else. Nothing added without a reason.

  • Perfectly Imperfect Produce
    Perfectly Imperfect Produce

    More than 50% of the fruits and vegetables in Wisdom come from produce that's nutritionally identical to grocery-store quality but cosmetically imperfect. Same nutrition, less waste. It's the right thing to do, and it makes for a better ingredient story.

  • Complete & Balanced
    Complete & Balanced

    Every Wisdom recipe is formulated to be nutritionally complete and balanced for dogs and cats. Not a supplement, not a topper. A full diet built on real food, gut-first thinking, and over 45 years of veterinary expertise.

How we treat our people is part of the same conviction.

The care we put into Wisdom extends to how we operate Riverstone, and the people who make it work. A facility that makes food this good requires a team that's genuinely invested. That's not an accident.

Your Questions, Answered

You ask and we answer! FAQs about Wisdom Air-Dried.

Where is Wisdom Dog Food made?

Wisdom is crafted in the USA at Riverstone, our own SQF-certified facility in Maryland. We didn’t partner with a co-packer. We built our own. Riverstone was designed from the ground up to make food differently, under Safe Quality Food (SQF) certification, a globally recognized standard for food safety, quality, and traceability, benchmarked by the Global Food Safety Initiative. This isn’t just a certification. It’s a commitment to accountability at every level. Because we own the facility, we oversee everything: – Ingredient sourcing and verification – Full lot traceability from ingredient to final bag – Rigorous quality and safety testing before any product is released Every batch is made with intention, and nothing leaves Riverstone until it meets our standards. At the center of it all is our gentle air-drying process, a slower, lower-temperature method that helps preserve nutrients, protect protein integrity, and maintain the natural flavor of real food. It’s not built on shortcuts or high-heat processing. We own the process. We stand behind every batch. We can tell you exactly where your dog’s food comes from, and how it was made. That’s Riverstone. That’s Wisdom.

Who formulated Wisdom Dog Food?

Wisdom is formulated by Dr. Bob Goldstein, a holistic veterinarian with more than 45 years of experience and deep expertise in canine and feline nutrition. He co-founded Earth Animal in 1979 with his wife, Susan, guided by a belief that still defines everything we do: Heart + Science. Every recipe is crafted under their direct oversight, from ingredient selection to production in our own Riverstone Kitchen in Maryland, where our gentle air-drying process protects nutrients, supports digestibility, and preserves the integrity of real food. This isn’t outsourced. It’s not built on shortcuts or high-heat processing. We own our standards. We control our process. We do it differently, on purpose. Because how you make it matters just as much as what you make. Learn more about Dr. Bob and Susan’s story.

Is Wisdom good for dogs with sensitive stomachs?

It’s built with them in mind. At Earth Animal, we believe health starts in the gut. When digestion is supported, everything else begins to fall into place. That philosophy, led by Dr. Bob Goldstein, is at the core of every Wisdom recipe. Why many sensitive dogs do well on Wisdom: Gentle by design Air-drying uses low temperatures, avoiding the harsh, repeated heat of extrusion, helping preserve nutrients and making the food easier on the digestive system. Real food. Nothing to decode. We use whole, recognizable ingredients. No artificial additives. No fillers. No vague or “mystery” inputs that can trigger unnecessary stress on the gut. Keep it simple when it matters Our Chicken and Turkey recipes are single-protein options, ideal for dogs who do better with fewer variables. Leave out what doesn’t belong No corn. No wheat. No soy. No artificial preservatives. Just clean, purposeful nutrition. What many pet parents notice:

  • Firmer, more consistent stools
  • Less gas and digestive upset
  • Steadier energy
  • A healthier skin and coat

Not overnight. But often within a few weeks, because the body is finally working with the food, not against it. A thoughtful approach Every dog is different. If your dog has known sensitivities or digestive challenges, take it slow, 10–14 days or longer, and consult your veterinarian when needed.

Where are the ingredients in Wisdom sourced?

Every ingredient in Wisdom is carefully sourced from trusted suppliers who meet our strict standards for food safety, animal welfare, and sustainability.

Our proteins are thoughtfully sourced:

  • Chicken & Turkey: GAP-rated, antibiotic-free from high-welfare farms
  • Venison, Beef, Bison: Grass-fed and pasture-raised
  • Fish (Sardines, Catfish): Wild-caught and sustainably sourced
  • Quail, Duck, Goose: Sustainably sourced and cage-free

Why do the Wisdom pieces look different from batch to batch?

Because Wisdom is made from real food. And real food doesn’t come off an assembly line looking identical every time. That kind of perfect uniformity usually comes from heavy processing, artificial colors, fillers, or manufacturing designed to make food look the same, rather than be the same in quality. That’s not how we make Wisdom. Wisdom is crafted from real muscle meat, nutrient-rich organs, and whole ingredients, then gently air-dried in our own kitchen. So yes, natural variation can happen. And in our view, that’s not a flaw. It’s part of the integrity of real food. What you may notice: Color may vary. Different proteins, organs, fruits, vegetables, and grains all carry their own natural pigments. Seasonal and agricultural variation can also subtly influence appearance. We don’t use artificial colors to force sameness from batch to batch. Size and shape may vary. Wisdom is air-dried, not extruded into perfectly uniform pellets. That means pieces may differ slightly in size, edge, or shape. Real ingredients and a gentler process create a more natural result. Texture may vary slightly. Because moisture levels in whole ingredients can vary naturally, one batch may feel a bit firmer or softer than another. That’s normal in a minimally processed food made from real ingredients. What never changes: Our standards. Every batch is still made to the same nutritional targets and the same uncompromising sourcing and manufacturing expectations. That means every bag still delivers:

  • The same high-quality ingredient standards
  • The same thoughtful sourcing
  • The same complete and balanced nutrition to meet AAFCO standards
  • The same careful production at Riverstone, our own SQF-certified facility in Maryland

In other words: The look may shift a little. The quality does not. In fact, a little variation is often one of the clearest signs that what you’re holding is real food—made with real ingredients, not engineered to look fake-perfect.

Why does Wisdom cost more than regular kibble?

Because it’s not made like kibble. And it’s not made with the same ingredients. Real food. No shortcuts. Wisdom starts with high-quality muscle meat, nutrient-rich organs, and whole foods, never the fillers, meals, or by-products used to bulk up conventional kibble. Our process is the difference. Most kibble is made with high heat and pressure. Wisdom is gently air-dried, preserving nutrients, protecting protein integrity, and honoring the food itself. It takes longer. It costs more. It’s worth it. More nutrition in every bite. Wisdom is naturally nutrient-dense, so you feed less. Smaller portions. More nourishment. A bag goes further than you’d expect. We don’t outsource our standards. Every batch is made in our own kitchen, Riverstone, so we control quality from start to finish. No compromises. No corners cut. Sourcing you can stand behind. Humanely raised, responsibly sourced proteins, GAP-rated poultry, grass-fed meats, and wild-caught fish. Ingredients raised with care simply cost more. And they should. Look beyond the bag. When you calculate cost per serving, not cost per pound, Wisdom is far more comparable to premium foods than it first appears. And for many dogs, the difference shows, in digestion, vitality, and overall health. Because how it’s made matters. And what goes in matters even more.
