Formula & Mathematical Methodology

Standard Mathematical Formula
Daily Raw Food = Ideal Body Weight × 2.0% to 3.0% | Ratio: 80% Muscle Meat, 10% Raw Bone, 5% Liver, 5% Secreting Organ

Formula Variables Defined

BWDog Target Weight(lbs or kg)

Healthy adult canine body mass

RateFeeding Percentage(% of BW)

Standard maintenance is 2.0% to 3.0% of adult body weight

Step-by-Step Calculation Example

Example: 50 lb Dog on 2.5% BARF Maintenance Diet

A 50 lb adult dog eating a standard 80/10/10 raw diet.

  1. Total daily food = 50 lbs × 0.025 = 1.25 lbs (20 oz)
  2. Muscle Meat (80%) = 16 oz (454 g)
  3. Raw Edible Bone (10%) = 2 oz (57 g)
  4. Liver (5%) = 1 oz (28 g)
  5. Other Secreting Organ (5%) = 1 oz (28 g)
Final Output: 1.25 lbs/day (20 oz / 567 g daily)

Key Assumptions

  • Raw bones must always be raw and never cooked to prevent splintering.

Biological Limitations

  • Raw diets require strict hygiene and consultation with a board-certified veterinary nutritionist to prevent nutritional deficiencies.
