Our nutrient targets look different from the free calculators and AI chatbots you have tried. That is intentional. Generic tools use dangerous linear weight multipliers, and AI simply aggregates conflicting internet blogs. Neither approach is clinically safe. Here is the forensic NRC 2006 math proving why our allometric (\(BW^{0.75}\)) engine is accurate, and why internet averages fail:
Before we dive into the deep clinical science below, here is the exact 6-step path your dog's profile takes through our engine the moment you press 'Calculate'. No magic, just sequential data processing.
This is how your 8-point input transforms into a clinically safe meal in less than 2 seconds:
We take your 8-point clinical profile and calculate the Resting Energy Requirement (RER) using Kleiber's Law: \(\text{RER} = 70 \times (\text{BW}_{\text{kg}})^{0.75}\). We then apply the specific breed and activity multipliers to establish the Daily Energy Requirement (DER).
Before generating your daily goalposts, the profile is route through 30+ clinical safeguards. This enforces absolute ceilings, such as capping Vitamin A at 15,000 IU/1000 kcal and applying IRIS Stage 2+ phosphorus restrictions for seniors.
As you build your bowl, the engine doesn't just add up raw weights. Because raw food contains 65–80% water, the engine automatically converts every ingredient to its Dry Matter (DM) basis in real-time, preventing false deficiency flags.
Before we check for gaps, we strip away what your dog cannot absorb. The engine applies NRC Bioavailability Coefficients directly to the ingredient yield (e.g., Raw meat Zinc is ~35% bioavailable). We calculate the Effective Yield so we only count the nutrients that actually enter the bloodstream.
Every absorbed nutrient is cross-referenced against the NRC Recommended Allowances. If a gap exists, the engine consults the 200g Volumetric Ceiling. If fixing the gap with whole foods requires an impractical volume, it automatically routes to a decimal-precise supplement recommendation.
When you log an observation, the engine maps qualitative
severity tags (normal, warning, danger) directly against
the exact bonePct, meatPct, and organPct of that day's
meal plan to isolate clinical triggers without arbitrary scoring.
Precision requires context. We cannot calculate a safe diet based on weight alone. First, we gather your dog's complete 8-point biological profile, then route it into the correct metabolic engine using Kleiber's Law: \(\text{RER} = 70 \times (\text{BW}_{\text{kg}})^{0.75}\).
To follow NRC 2006 metabolic scaling safely, our engine requires your dog's complete 8-point physiological profile before it calculates a single calorie.
A growing Great Dane puppy, an adult Dalmatian, and a senior Labrador with kidney issues require entirely different clinical math. Raw & Well doesn't use a generic template; we route your dog through one of three specialized nutritional pipelines.
Puppies do not grow in neat \"age buckets.\" They follow a continuous metabolic curve. Small errors in calcium or phosphorus during this window lead to irreversible Developmental Orthopedic Disease (DOD).
Raw Multiplier = 3.2 × (e^(-0.87p) - 0.1)
Final Multiplier = Math.max(Raw Multiplier, 1.4) // The Maturity Bridge
Practical Implications: Instead of you guessing your puppy's growth rate, our app mathematically throttles calcium intake exactly when their bones are most vulnerable. The Maturity Bridge ensures they never hit a caloric cliff when transitioning to adulthood, maintaining a safe 1.4x baseline.
A 20kg Bulldog and a 20kg Border Collie burn energy at wildly different rates. Our engine utilizes Kleiber's Law, modified by a proprietary matrix of 191 breed multipliers and genetic guardrails.
RER = 70 × (Body Weight in kg)^0.75
DER = RER × [Activity × Breed × Neuter × BCS × POMC]
Practical Implications: A 5kg Yorkie burns fuel differently than a 5kg Bulldog. We calculate exact calories based on their genetic metabolism, then apply your dog's individual lifestyle modifiers.
As dogs age, they naturally lose muscle mass. Unless they have a confirmed kidney diagnosis, senior dogs actually need MORE high-quality protein to survive. Our engine dynamically separates healthy aging from clinical renal failure.
Target = Base Protein Requirement × 1.3 (Sarcopenia Boost Factor)
Practical Implications: We don't starve your senior dog of protein just because they are old. We actively boost amino acids to prevent muscle wasting (sarcopenia), unless their kidneys specifically require restriction.
Once we know your dog's baseline, the engine applies hard constraints before a single ingredient is suggested. We lock in strict NRC safety ceilings to prevent mineral toxicity and ensure structural health.
We don't just calculate minimums; our engine executes a sequential data-processing pipeline that runs your dog's profile through active clinical checkpoints before you ever see a recipe.
Applies individual energy adjustments across 191 distinct breeds, including a 25% energy reduction for Labradors with confirmed POMC mutations and 20% Taurine scaling for Sighthounds.
Enforces a strict 1,600mg/day absolute Phosphorus ceiling for large breed puppies to prevent Orthopedic Disease. The engine automatically rebalances Calcium based on Phosphorus intake—using a 1.3:1 ratio for Giant breeds.
Hard ceilings enforced to prevent acute toxicity, including strictly mapped Safe Upper Limits for Iodine (2,750mcg/1000kcal) and Vitamin D.
Strict phosphorus (capped at 700mg/1000kcal) and protein restriction protocols activate at IRIS Stage 2+ and scale through Stage 4, tied directly to your dog's confirmed CKD diagnosis.
Zero-Estimation Policy: If an ingredient lacks verified data for an essential nutrient, the engine flags a CRITICAL DEFICIENCY. We never guess. Additionally, your dog's profile is locked to your secure UID. The moment you log out, our \"Ghost Data\" system wipes the temporary memory of your dog's specific nutrient needs. No digital footprints.
As you build your bowl, the engine never compares wet weights to NRC standards. Because raw food contains 65–80% water, doing so produces systematic false deficiency flags. Every ingredient is converted to its Dry Matter (DM) basis in real-time before any nutrient check runs.
DM Nutrient (mg) = Raw Nutrient (mg/100g) × [100 / (100 − Moisture%)] × Ingredient Weight (g) / 100
Practical Implications: Raw chicken breast at 74% moisture has only 26g of actual dry matter per 100g fed. If the engine compared the wet-weight zinc content directly to the NRC daily target, it would flag a zinc deficiency on almost every meal—even when the dog is meeting requirements. The DM conversion eliminates this class of false alarm entirely.
Dry Matter weight is what's in the food. Bioavailability is what your dog can actually use. The engine applies NRC Bioavailability Coefficients to calculate the Effective Yield—the fraction of each nutrient that actually enters the bloodstream.
Zinc (Raw Meat)
~35% Bioavailability CoefficientCalcium (Bone)
~65% Bioavailability CoefficientIron (Muscle Meat)
~25% Bioavailability CoefficientManganese (Plant Sources)
~12% Bioavailability Coefficient
Effective Yield (mg) = DM Nutrient (mg) × NRC Bioavailability Coefficient
Practical Implications: A bowl containing 15mg of zinc on a dry-matter basis only delivers ~5.25mg of absorbable zinc (at 35% bioavailability). We check that 5.25mg—not the 15mg label value—against the NRC Recommended Allowance. This is the difference between a clinical calculator and a food log.
Every absorbed nutrient is cross-referenced against the NRC Recommended Allowances. When a gap exists, the engine follows a Food-First, Supplement-Supported decision matrix that closes deficiencies without overloading the bowl or the dog's caloric budget.
Our \"Food-First, Supplement-Supported\" algorithm follows a 3-step decision matrix to ensure safety without overstuffing the bowl.
Our engine has hard-coded physical limits. If fixing a Zinc gap requires an \"impractical\" amount of food that would cause digestive distress, the engine automatically triggers a supplement recommendation instead.
If a dog is already at their daily calorie limit, adding more food to fix a gap causes weight gain. The engine \"anchors\" the calories and uses a zero-calorie supplement bridge to protect the dog's Body Condition Score.
Whole foods vary. Supplements allow the engine to fill a precise 14.5mg gap with surgical accuracy, hitting the NRC Recommended Allowance exactly without the \"scoop and hope\" guesswork.
From complex math to daily peace of mind.
Don't wait for symptoms of deficiency to show up. As you build a recipe, our real-time Deficiency Meter audits your ingredients against NRC requirements. Instantly see if you're missing Zinc, Copper, or Manganese, and get one-click whole-food booster suggestions.
Transitioning from kibble can feel overwhelming. Our planner translates your dog's optimal math into a practical, weekly shopping list. You'll know exactly how many grams of meat, bone, and organ to prep—right down to the decimal.
When you log an observation, the engine maps qualitative severity tags directly against that calendar day's exact macronutrient ratios to isolate clinical triggers—without arbitrary scoring. Built for the kibble-to-raw transition and long-term gut stability monitoring.
Built to manage the 'Kibble-to-Raw' transition for beginners and long-term stability for pros, this matrix eliminates trial-and-error feeding.
| Severity Tag | Observation | Engine Action |
|---|---|---|
normal |
Ideal / Firm stool, stable energy | Day marked stable. Macro ratios logged as baseline. |
info |
Minor softness, mild itching | Flag recorded. Overlay checks for elevated organPct that day. |
warning |
Unformed stool, repeated itching | Correlation check: bonePct, meatPct, new protein
introduced. |
danger |
Liquid / diarrhea, lethargy | Traceable trigger identified against that day's organPct and ingredient
list. |
There is no arbitrary numeric score. The engine uses a forensic date-based overlay
instead. Each symptom log is matched to that calendar day's exact macronutrient breakdown — the
bonePct, meatPct, and organPct from your meal plan. If a
danger flag for liquid stool coincides with a high-organ day or the introduction of a
new protein, the engine surfaces a traceable trigger, not a guess.
You provide the observations; the app provides the clinical map.
Our calculations have been reviewed by board-certified veterinary nutritionists and validated against laboratory analysis of 47 complete diets.

Yes. Every calculation in this engine is derived directly from the National Research Council's Nutrient Requirements of Dogs and Cats (2006). We use Recommended Allowances (RA) as the default floor and Safe Upper Limits (SUL) as absolute ceilings.
Most calculators use linear scaling (weight × multiplier). We use metabolic scaling (\(kg^{0.75}\)) based on Kleiber's Law, which reflects how energy actually works in living organisms. Small dogs need more per kg; large dogs need less.
This tool is designed to complement veterinary care, not replace it. We encourage you to share our calculations with your vet. Many vets appreciate having precise nutritional data to work with. Our engine is built for collaboration, not conflict.
