Natural Diet Audit
Raw Food (BARF/PMR) Portion Specialist
The 10% organ meat should be 5% liver and 5% other secreting organs (kidney, spleen, etc.). Never feed cooked bones; they splinter and cause internal damage.

✅ What This Calculates + Why It Matters
The Raw Dog Food Calculator is a professional-grade formulation tool designed for owners following the BARF (Biologically Appropriate Raw Food) or PMR (Prey Model Raw) feeding methods. This calculator determines the precise daily food weight a dog requires based on their body mass and life stage, and then breaks that weight down into the scientifically recognized 80/10/10 ratio. This ratio ensures that the dog receives the correct balance of energy-providing muscle meat, mineral-rich edible bone, and nutrient-dense organ meats.
Why is portion precision so critical in raw feeding? Unlike commercial kibble, which is processed to a uniform nutrient profile, raw ingredients are bioavailable and nutrient-dense. Overfeeding raw food can lead to rapid weight gain and obesity, while underfeeding—especially in growing puppies—can cause significant developmental issues. Furthermore, the Calcium-to-Phosphorus ratio, which is managed by the 10% edible bone component, must be accurately calculated to prevent skeletal deformities in large-breed dogs. This tool eliminates the guesswork, providing a safe, repeatable baseline for a balanced diet.
This calculator also accounts for the dramatically different metabolic needs of puppies. A 4-month-old puppy may require 8% or more of its body weight in food to support its rapid growth phase, whereas a senior or inactive dog may stay at a healthy weight on just 2%. By using this tool, you ensure your dog’s bowl is filled with the exact amount of "ancestral nutrition" they need to thrive.
The 80/10/10 Rule
This "Golden Rule" of raw feeding mimics the composition of a whole prey animal: 80% Muscle Meat (for protein and fat), 10% Edible Raw Bone (for calcium), and 10% Organs (5% Liver and 5% other secreting organs like kidney or spleen, acting as a natural multivitamin).
✅ The Formula Explained Simply
The daily portion is calculated as a percentage of the dog's ideal adult body weight (or current weight for growing puppies):
Adult Maintenance: 2.5% of Body Weight
Active/Working: 3% of Body Weight
Puppy (High Growth): 8-10% of Body Weight
Calculation Steps:
- Step 1: Multiply the dog's weight by the chosen feeding percentage to find the Total Daily Weight.
- Step 2: Convert lbs to ounces (16 oz per lb) for more precise kitchen measurement.
- Step 3: Apply the 80/10/10 split to the total ounces to find the target weights for Meat, Bone, and Organs.
✅ 3-5 Real-World Examples
Example 1: The Sedentary Bulldog (50 lbs)
Dog Weight: 50 lbs | Rate: 2% (Inactive).
Total: 1.0 lb (16 oz) per day.
Ratio: 12.8 oz Meat | 1.6 oz Bone | 1.6 oz Organ.
Example 2: The Active Shepherd (75 lbs)
Dog Weight: 75 lbs | Rate: 3% (Active).
Total: 2.25 lbs (36 oz) per day.
Ratio: 28.8 oz Meat | 3.6 oz Bone | 3.6 oz Organ.
Example 3: The Growing Puppy (20 lbs)
Dog Weight: 20 lbs | Rate: 10% (High Growth).
Total: 2.0 lbs (32 oz) per day.
Ratio: 25.6 oz Meat | 3.2 oz Bone | 3.2 oz Organ.
✅ FAQ Section (Google PAA Targeted)
Is it safe to feed my dog raw bones?
Yes, but only if they are raw. Raw edible bones (like chicken necks, wings, or backs) are soft, flexible, and fully digestible. Cooked bones, however, become brittle and splinter, which can cause fatal punctures in the digestive tract. Always monitor your dog while they eat bones.
What is the difference between BARF and PMR?
PMR (Prey Model Raw) focuses strictly on animal-based ingredients (Meat/Bone/Organ). BARF (Biologically Appropriate Raw Food) allows for the inclusion of some vegetables, fruits, and seeds (usually around 10% of the meat portion) to provide additional fiber and antioxidants.
Can I feed a raw diet to a puppy?
Yes, but it must be meticulously balanced. Puppies have a very small margin for error regarding Calcium and Phosphorus. Most experts recommend using a pre-balanced commercial raw "complete" grind for puppies until they reach adulthood to ensure proper skeletal growth.
Why are organ meats so important?
Organ meats are the "multivitamins" of the raw diet. Liver is exceptionally high in Vitamin A and Copper, while other organs like kidney and spleen provide essential B vitamins and minerals that are not found in significant amounts in muscle meat.

✅ AI Raw Specialist Advice
Our AI Raw Specialist provides a "Nutritional Completeness Audit" for every formulation. It emphasizes the "Rule of Three Proteins," explaining that feeding only one type of meat (like chicken) indefinitely will lead to amino acid deficiencies. The AI specifically flags the importance of "Liver Management"—reminding owners that while liver is a superfood, an overdose can lead to Vitamin A toxicity. It also suggests adding a "Functional Fiber" source, like pureed pumpkin, for dogs transitioning to raw to ensure digestive stability during the first 14 days of the new diet.
The BARF Diet Guide
Raw feeding (Biologically Appropriate Raw Food) focuses on providing dogs with a diet similar to what they would eat in the wild.
The 80-10-10 Rule
A balanced raw meal typically consists of 80% muscle meat, 10% edible bone, and 10% organ meats (half of which should be liver).
