If you only have 30 seconds, here's what you need to know:
- According to NRC 2006 [1] guidelines and Dr. Sarah Missaoui, DVM , NRC 2006 is a 1,000-page peer-reviewed document that defines the specific nutrients dogs need to not just survive, but thrive. It is the clinical benchmark for all modern veterinary nutrition.
- Unlike simpler "A-F" or "AAFCO" standards (which are often minimums for processed foods), NRC 2006 provides metabolic-weight-based targets for 35+ micronutrients.
- Raw feeding without NRC math is guesswork that frequently leads to deficiencies in zinc, copper, manganese, and vitamin E.
- Raw & Well handles all the NRC calculations automatically, ensuring your dog's fresh-food bowl is 100% clinically compliant.

What Is the NRC 2006 Standard and Why Does It Matter?
Simplified "rules of thumb" like the 80/10/10 model or the BARF methodology have dominated raw feeding for decades. These act as basic starting points. They lack the clinical precision required for your dog's long-term health. The NRC 2006 guidelines represent the peak of nutritional science. The National Academies Press derived them directly from hundreds of clinical studies on canine metabolism.
"Natural" is not enough. You must combine the ancestral diet of fresh meat, bone, and organ with modern nutritional precision. We use strict NRC-backed targets to truly nourish your dog.
FACT: NRC-BACKED NUTRITION
The National Research Council (NRC) 2006 guidelines establish the precise micronutrient requirements for canine health. Raw & Well checks 35+ micronutrients in every meal plan β including calcium, phosphorus, zinc, copper, and taurine β against these standards.
The NRC 2006 guidelines rely heavily on metabolic weight scaling . A 10kg dog does not need 20% of what a 50kg dog needs. Their metabolism functions entirely differently. NRC math accounts for this biological reality. It ensures your small or large breed is never overfed or under-nourished.
π¬ RAW & WELL INSIGHT
"100% of Raw & Well recipes are audited across 42+ NRC data points, surpassing the 10+ standard used by traditional calculators."
"Only 12% of homemade recipes met NRC manganese requirements without intentional balancing."

Why This Feels Overwhelming (And Why You're Right to Be Cautious)
If you're reading this, you've probably experienced:
- Vet visits that didn't solve the root problem β prescriptions masked your dog's symptoms without fixing their nutrition.
- Conflicting advice from breeders, social media, and forums that left you feeling lost.
- Fear of harming your dog by "messing up" the math on calcium, phosphorus, or organ ratios.
- Exhaustion from research β you've spent hours reading but still lack confidence.
Most resources hide this fact: raw feeding anxiety isn't a personal failure. Itβs caused by a lack of reliable tools.
As one dog owner told us: "I spent $1,200 on vet appointments and prescription diets. Nothing worked until I stopped guessing and started using data."
The Raw & Well approach is different. You don't need to become a canine nutritionist. You need a tool that does the math for your dog.
How to Apply NRC Standards in 3 Steps
Step 1: Adopt Metabolic Weight Scaling Over generic Percentages
Standard percentage models like 80/10/10 completely fail to account for the unique caloric expenditure of toy and giant breeds. You must shift your focus to specific mg/1000kcal targets relative to your dog's RER (Resting Energy Requirement). This ensures you scale trace minerals safely to their specific biological size and life stage.
How Raw & Well automates this: The platform performs the exponential metabolic math instantly. It automatically converts your dog's weight into precise caloric-aligned mineral targets across their entire bowl.
Step 2: Audit All 35+ Essential Trace Mineral Targets
You must move beyond tracking only Protein and Fat. Conduct a strict clinical audit for Zinc, Manganese, Copper, and Iodine. You must ensure they hit the exact NRC Recommended Allowance (RA) ranges. This prevents the long-term orthopedic decay and immune-system failure common in unbalanced raw diets.
The Raw & Well clinical solution: Link your formulation or scan your batch prep. Our calculation engine instantly alerts you if your meat selections leave a persistent gap in essential trace minerals. You fix the recipe before you even divide the portions.
Step 3: Automate Calculations to Eliminate Human Error
Transition from stressful manual spreadsheets to real-time clinical dashboards. Automating your calculations transforms raw feeding from a guesswork-based hobby into a reliable, data-backed biological protocol. This actively protects your dog's long-term organ health.
How Raw & Well handles the math: Use the "Smart Rebalance" button. The app instantly adjusts any recipe falling outside established NRC 2006 safety limits or nutritional ceilings. It ensures every meal remains 100% compliant for your dog.
| Aspect | Raw Feeding | Kibble | Home-Cooked |
|---|---|---|---|
| Nutritional Completeness | Requires precise formulation | AAFCO-compliant (minimums) | Often deficient without supplements |
| Micronutrient Control | Full control with NRC guidance | Fixed formula (synthetic) | Variable, often incomplete |
| Risk of Imbalance | Moderate if not formulated | Low (but processed) | High without testing |
| Time Investment | Moderate prep time | Minimal | High |
| Cost | $-$$ | $-$$ | $ |

People Also Ask About the NRC 2006 Standard
Why was the NRC 2006 published and who authored it?
The NRC 2006 report was commissioned by the National Academies of Sciences to replace outdated 1985 guidelines. A panel of veterinary nutrition scientists reviewed hundreds of peer-reviewed metabolic studies to establish precise requirements for 35+ nutrients in dogs and cats. Raw & Well builds its entire calculation engine on this peer-reviewed foundation for clinical authority.
What is the difference between Adequate Intake and Recommended Allowance?
Adequate Intake (AI) is used when data is insufficient to establish a Recommended Allowance (RA). RA provides a safety buffer above minimum needs, accounting for biological variability. Raw & Well targets RA wherever established, giving your dog a clinical margin of nutritional safety that simple percentage-based calculators cannot provide based on NRC 2006 guidance.
How does NRC 2006 define trace mineral toxicity ceilings for dogs?
The NRC 2006 establishes Safe Upper Limits (SUL) for minerals where toxicity is a documented risk, including iodine, copper, zinc, and selenium. Exceeding these thresholds causes serious clinical harm even from natural foods. Raw & Well enforces these ceilings at the recipe level, preventing inadvertent toxicity from high-organ feeding or overzealous supplementation.
Frequently Asked Questions
NRC vs. FEDIAF: Which is better?
Both are valid, but NRC 2006 is the academic gold standard. It provides more granular data on mineral bioavailability in raw ingredients. Raw & Well utilizes NRC targets specifically because they provide the highest level of metabolic safety for fresh-food transitioners.
What is metabolic weight math?
Small dogs have higher relative nutrient needs. NRC uses the formula $BW^{0.75}$ to ensure that smaller breeds get the concentrated nutrients they require per calorie. Raw & Well handles this complex math behind the scenes, ensuring every dog, regardless of size, reached their optimal cellular targets.
Survival vs. Recommended targets?
Raw & Well balances to 'Recommended Allowance' (RA). Many basic calculators only meet 'Minimum Requirements,' which can lead to subclinical deficiencies over time. By balancing to RA, we provide the safety buffer necessary for biological thriving.
