What's inside

The whole ingredient list: Beef Liver.

Most dog treats have ingredient lists that read like a chemistry experiment. Ours has one line.

Beef liver is one of the most nutrient-dense foods a dog can eat: rich in protein, iron, vitamin A, and B vitamins. Before commercial pet food, dogs ate organ meat regularly. We're just bringing that back.

  • Beef liver from Zinniker Farm, Elkhorn, Wisconsin
  • Slowly dehydrated to preserve natural nutrients
  • No fillers, no binders, no preservatives
  • No artificial colors or flavors
The Math Behind the Bag

One pound of raw liver.
One four-ounce bag.

Dehydration removes only water, never nutrients. It takes close to a full pound of fresh, pasture-grazed beef liver to produce each 4 oz bag. You are feeding your dog the nutritional equivalent of nearly a pound of fresh organ meat, in a shelf-stable form.

Where it comes from

Zinniker Family Farm has been doing this since 1943.

The Zinniker family has been practicing Biodynamics, a more comprehensive approach to land stewardship, for over 80 years, long before "regenerative" was a selling point.

Their cattle graze on open pasture year-round. No pesticides. No feedlots. No shortcuts. The liver we use comes directly from their butcher, using the whole animal, the way it was always done.

Chuck Ginsberg

Founder · Elkhorn, Wisconsin

Chuck has been thinking about dog nutrition differently for a long time. It started in 1996 with Elvis, a 220-pound English Mastiff who couldn't eat dry dog food without getting sick. After doing some research, Chuck learned that the dog food was making Elvis sick. A veterinarian Chuck trusted, one who had been practicing since the 1960s, gave him a different answer: switch to real food. Chuck switched Elvis to raw. The problems cleared up within weeks and never came back, ever.

"Before commercial kibble and fast food, dogs ate real food, the leftovers from our plates. That's all we're doing here. Bringing back high-quality food."

That experience sent Chuck looking for health giving food, and eventually to Zinniker Family Farm, one of the oldest continuously operating biodynamic farms in North America. He spent years learning their Biodynamic approach: focus on soil fertility. No pesticides. No chemicals.

"Healthy soil leads to nutritious plants for the cows to graze, which gives us nutrient dense food that supports good health. Clean animals, closed loop, nothing wasted, no shortcuts."

Most people do not eat organ meat which happens to be the most nutritious part of an animal. Chuck saw that as an opportunity and a responsibility.

Natural Dog Health exists because Chuck couldn't find what he was looking for on a store shelf. One ingredient. One farm. Nothing added. So he built it himself, hand-slicing and drying every bag out of his Elkhorn kitchen, the same way he feeds his own dogs. This is what he gives them. Now you can have the same exacting quality for your dog.

FAQ

Common Questions

Why beef liver specifically?
Liver is one of the most nutrient-dense foods a dog can eat, rich in protein, vitamin A, B vitamins, iron, and copper. Before commercial pet food, organ meat was a regular part of a dog's diet. Muscle meat is good. Organ meat is better. We're just bringing back what dogs ate before there was a bag to buy.
What is biodynamic farming, and why does it matter for my dog?
Biodynamic farming is a holistic approach to agriculture developed in the 1920s that treats the farm as a self-sustaining ecosystem. It goes beyond organic: no synthetic pesticides or fertilizers, no GMOs, closed-loop fertility (the farm feeds itself), and farming practices tied to natural rhythms. Zinniker Family Farm has been practicing biodynamics since 1943, long before regenerative agriculture became a marketing term. For your dog, it means the animal that produced this liver lived its entire life on open pasture, eating what cattle are meant to eat. Healthier soil grows healthier grass. Healthier grass raises healthier cattle. Healthier cattle produce cleaner, more nutrient-dense organs. The chain matters.
Why is there only one ingredient?
Because that's all there needs to be. Most commercial treats use liver as a flavoring on top of grain, starch, and binders. We use liver as the entire product. No fillers, no preservatives, no ingredients you'd have to look up.
Is beef liver actually good for my dog?
Beef liver is one of the most nutrient-dense foods a dog can eat. It's naturally high in protein, vitamin A, B12, folate, iron, and copper, nutrients that support energy, coat health, and normal organ function. Dogs ate organ meat regularly before commercial pet food existed. We're not adding anything or making any claims about what it will do for your dog. We're just giving you the cleanest version of something dogs have always eaten.
If it's so nutritious, why is it called a treat?
Honestly, "treat" is just the closest existing category. This is a single whole food, beef liver, dried and bagged. There are no treat ingredients in it. No grain, no starch, no flavoring, no binders. We call it a treat because that's how most people will use it, but what's in the bag is closer to food than anything you'd find in the treat aisle. Feed it accordingly.
How much should I give my dog?
At 1 to 2 treats per day for a small dog, one bag typically lasts one to two weeks. For a large dog at a larger daily amount, plan on replenishing more frequently. Because pieces vary in size by batch, use weight as your guide rather than counting pieces. These are dense, nutrient-rich treats, not small training nibbles.
What does the research say about processed dog food?
A 2026 independent study by the Clean Label Project tested 79 top-selling dog foods and found that dry kibble contains dramatically higher levels of contaminants than fresh or minimally processed alternatives, including up to 21x more lead, 19x more mercury, 10x more cadmium, and 24x more acrylamide, a carcinogen formed during high-heat processing. Fresh and frozen food tested cleanest across every category. We're not kibble, and we're not processed. One ingredient, slow dehydrated, nothing added. You can read the full study at cleanlabelproject.org/dog-food-study.
Can I give these to a puppy or a senior dog?
Yes. The single-ingredient format makes it easy to know exactly what your dog is getting, which is especially useful for dogs with sensitivities or older dogs on restricted diets. As always, consult your vet if your dog has specific health conditions.
How many treats are in a bag, and what does that work out to per day?
Each bag is filled by weight, so the number of pieces varies from batch to batch depending on the thickness and density of individual slices. Beef liver is a whole-muscle organ, and no two pieces are identical. Some batches run leaner and slice thinner; others are denser. That variability is a feature of real, single-ingredient food, not a quality issue. Every bag contains 4oz of beef liver and nothing else.
Is there any risk of vitamin A toxicity from feeding liver?
Liver is nutrient-dense, which is exactly why it's valuable and exactly why it's a treat rather than a meal replacement. Fed as directed, 1 to 6 pieces daily depending on dog size, there is no meaningful risk of vitamin A toxicity. Toxicity from liver requires sustained high-volume feeding over long periods. These treats are designed to supplement a balanced diet, not replace it. If your dog has a specific health condition, ask your vet before adding any new food.
What if my dog doesn't like them?
If your dog tries them and isn't interested, reach out. We'll make it right. Dogs have turned their noses up at stranger things, but liver tends to have the opposite problem.
