The 80/10/10 Raw Diet: A Complete Guide (And Why It Fails NRC 2006)

Why the ratio still leaves you uncertain

You can follow 80/10/10 and still end up guessing. The ratio does not answer one question: does this recipe cover micronutrients for this dog at this energy intake.

NRC 2006 frames nutrient adequacy as a concentration problem because dogs tend to eat to satisfy energy needs. A ratio can look clean and still miss zinc, manganese, or long-chain omega-3s if you do not track them.

Dr. Missaoui’s clinic rule: use 80/10/10 as a shopping framework, then review nutrients per 1,000 kcal ME.

What Is the 80/10/10 Rule and Why Does It Matter?

The 80/10/10 rule is a common prey-model convention: 80% muscle meat, 10% bone, and 10% secreting organ. It helps you shop and portion food. It does not tell you whether zinc, manganese, vitamin E, or omega-3 intake matches NRC guidance for your dog’s life stage.

• 80% Muscle Meat: Muscle meat supplies most protein and fat. It contributes amino acids and some B vitamins, but it does not guarantee micronutrient adequacy on its own.
• 10% Edible Bone: Bone is a calcium and phosphorus source. The actual mineral intake depends on the cut (neck vs wing vs carcass) and the amount of bone in that cut. Use tracking to confirm your calcium:phosphorus balance.
• 10% Secretory Organ: Organs concentrate certain vitamins and minerals. Liver is a major vitamin A source. Different organs contribute different nutrients, and “10% organ” does not automatically match NRC guidance.

What the ratio controls vs what you still have to verify

• Micronutrients: 80/10/10 doesn’t set targets; NRC often expresses them per energy intake, so you audit per 1,000 kcal ME.
• Minerals: “10% bone” does not guarantee a calcium plan because bone-in cuts vary widely.
• Trace minerals: zinc and manganese are common “silent gaps” when a dog eats a narrow ingredient rotation.
• Omega‑3s: EPA+DHA aren’t specified by the ratio; you only know what you’re feeding if you measure or calculate.

NRC 2006 is a reference frame. It gives you nutrient targets in consistent units, often per energy intake. The prey-model ratio assumes rotation covers everything; in practice, many dogs eat a narrow set of proteins and organs, and gaps can hide in plain sight if you never audit per 1,000 kcal ME.

What 80/10/10 Gets Right (and Wrong)

The Benefit: You get a strong macronutrient balance of protein and fat. The rule offers a clear starting point when moving your dog away from kibble.

The Flaw: Most ratio diets ignore mineral interactions. As one example, high calcium intake can reduce zinc absorption in some contexts, which is one reason nutrient totals matter. They also treat all 'organs' as interchangeable, even though liver and kidney contribute different nutrient profiles.

How to use 80/10/10 without pretending it’s a complete standard

Use it for structure. It’s a shopping and portioning framework: muscle meat, edible bone, secreting organ.

Then audit what the ratio can’t see. Zinc, manganese, vitamin E, and EPA+DHA don’t get “set” by percentages.

Correct one gap at a time. If you prefer food-first corrections, pick them based on the measured gap (not on tradition).

Use stool as feedback, not as a diagnosis. Chalky/white stool often means too much bone; persistent changes deserve a broader look.

Common questions (kept short)

Does the 80/10/10 diet work for small dogs?

It can, but the margin for error is smaller. Small dogs can eat fewer grams of food per day, so micronutrient coverage per 1,000 kcal matters. Treat 80/10/10 as a starting framework, then verify trace minerals and fatty acids against NRC 2006 guidance.

Can I feed 80/10/10 to a growing puppy?

Be careful. Puppies use different NRC tables than adult maintenance, and mineral targets are sensitive during growth. If you feed raw to a puppy, use an NRC-based formulation and get veterinary guidance.

Why is 80/10/10 missing Vitamin E?

Because the rule is a ratio, not a vitamin target list. Vitamin E needs depend on diet composition, especially fat and PUFA load. If you are not calculating micronutrients per 1,000 kcal ME, it is hard to confirm vitamin E coverage from muscle meat and bone alone.
