How to Use the Raw Diet Calculator for Dogs (BARF & PMR Models)

  1. Select raw diet model: BARF (70-10-10-10) or PMR (80-10-10).
  2. Enter dog target weight and daily feeding percentage (typically 2% to 3% of body weight for adult dogs).
  3. View total daily raw food weight and exact gram breakdowns for Muscle Meat, Raw Bone, Liver, and Other Organs.

Clinical Methodology & Formula Breakdown

Calculates total raw daily weight (Body Weight * Feeding Percentage) and distributes into standard model macronutrient components.

Clinical Veterinary Formula
BARF: 70% Muscle Meat, 10% Raw Edible Bone, 5% Liver, 5% Secreting Organ, 10% Vegetables/Seeds. PMR: 80% Muscle Meat, 10% Raw Edible Bone, 5% Liver, 5% Secreting Organ.

Worked Clinical Example

Scenario
A 20 kg (44 lb) adult dog fed a BARF diet at 2.5% daily weight ratio.
Mathematical Calculation
Total Daily Raw = 20 kg * 0.025 = 0.50 kg (500g). BARF breakdown: Muscle Meat (350g), Bone (50g), Liver (25g), Organ (25g), Veggies (50g).
Veterinary Interpretation
Feed 500 grams total per day split into two 250g meals.

Frequently Asked Questions

What feeding percentage should I use for my raw-fed dog?

Inactive/Senior: 2.0% of target weight. Normal Adult: 2.5%. Active/Working: 3.0% - 4.0%. Puppies: 5.0% - 10.0% of current weight.

What qualifies as a raw edible bone?

Soft non-weight-bearing bones that can be completely crushed, such as chicken necks, wings, duck necks, and turkey necks. Never feed cooked bones!

Why is liver calculated separately from other organs?

Liver is extremely dense in Vitamin A. Overfeeding liver can lead to Vitamin A toxicity, so it is strictly capped at 5% of total diet.

What are secreting organs in raw feeding?

Organs that secrete a substance, such as kidney, spleen, pancreas, thymus, and brain. Gizzards and heart count as muscle meat, not secreting organ.

Should I consult a veterinary nutritionist before going 100% raw?

Yes! Unbalanced home-prepared raw diets can easily result in calcium-to-phosphorus imbalances and severe nutrient deficiencies.
