Table 3: Energy Requirements (Resting Energy Requirement – RER) for Dogs

Dog Weight (kg)	RER (kcal/day)	Calculation Method
5	197	70 × (5)^0.75
10	394	70 × (10)^0.75
20	787	70 × (20)^0.75
30	1177	70 × (30)^0.75
40	1566	70 × (40)^0.75

Essential Formulas for BARF Diet Calculator for Dogs

1. Resting Energy Requirement (RER)

The RER represents the baseline energy a dog requires at rest to maintain vital functions.

  RER = 70 × (Body Weight in kg)0.75

Body Weight (kg): The dog’s weight in kilograms.
Exponent 0.75: Represents metabolic scaling based on body mass.
70: A constant derived from metabolic studies in mammals.

2. Daily Energy Requirement (DER)

DER adjusts RER based on activity, life stage, and physiological status.

  DER = RER × Activity Factor

Activity Factor: Multiplier based on dog’s lifestyle:

1.2 – 1.4 for neutered adult dogs with low activity
1.5 – 1.8 for active adult dogs
2.0 – 5.0 for working or highly active dogs
3.0 – 8.0 for puppies (growth phase)

3. Total Daily Food Intake (grams)

Calculates the total grams of BARF diet to feed daily based on DER and diet energy density.

  Total Food (g) = (DER in kcal) ÷ (Energy Density of BARF diet in kcal/g)

Energy Density: Average kcal per gram of BARF diet, typically 1.2 – 1.5 kcal/g depending on fat content.

4. Component Weight Calculation

Determines the weight of each BARF diet component based on percentage ratios.

  Component Weight (g) = Total Food (g) × Component Percentage

Component Percentage: Expressed as a decimal (e.g., 0.40 for 40%).

Detailed Real-World Examples of BARF Diet Calculator for Dogs

Example 1: Adult Moderate Activity Dog (25 kg)

Calculate the daily BARF diet for a 25 kg adult dog with moderate activity level.

Step 1: Calculate RER

  RER = 70 × (25)0.75

Calculate 25^0.75:

25^0.75 ≈ 25^(3/4) ≈ 11.18

Therefore:

  RER = 70 × 11.18 = 782.6 kcal/day

Step 2: Apply Activity Factor (Moderate = 1.6)

  DER = 782.6 × 1.6 = 1252.2 kcal/day

Step 3: Calculate total food intake assuming energy density = 1.3 kcal/g

  Total Food = 1252.2 ÷ 1.3 = 963.2 g/day

Step 4: Calculate component weights based on BARF ratios

Component	Percentage	Weight (g)
Raw Meaty Bones (45%)	0.45	963.2 × 0.45 = 433.4 g
Muscle Meat (35%)	0.35	963.2 × 0.35 = 337.1 g
Organ Meat (12%)	0.12	963.2 × 0.12 = 115.6 g
Vegetables & Fruits (8%)	0.08	963.2 × 0.08 = 77.1 g

This breakdown ensures balanced nutrition tailored to the dog’s energy needs and activity level.

Example 2: Puppy Growth Phase (10 kg, High Activity)

Calculate the daily BARF diet for a 10 kg puppy with high activity.

Step 1: Calculate RER

  RER = 70 × (10)0.75

Calculate 10^0.75:

10^0.75 ≈ 5.62

Therefore:

  RER = 70 × 5.62 = 393.4 kcal/day

Step 2: Apply Activity Factor (Puppy growth = 3.0)

  DER = 393.4 × 3.0 = 1180.2 kcal/day

Step 3: Calculate total food intake assuming energy density = 1.4 kcal/g

  Total Food = 1180.2 ÷ 1.4 = 843 g/day

Step 4: Calculate component weights based on BARF ratios

Component	Percentage	Weight (g)
Raw Meaty Bones (40%)	0.40	843 × 0.40 = 337.2 g
Muscle Meat (40%)	0.40	843 × 0.40 = 337.2 g
Organ Meat (15%)	0.15	843 × 0.15 = 126.5 g
Vegetables & Fruits (5%)	0.05	843 × 0.05 = 42.2 g

This feeding plan supports rapid growth and high energy expenditure typical of puppies.

Additional Technical Considerations for BARF Diet Calculations

Energy Density Variability: The kcal/g of BARF diets can vary significantly based on fat content. Fat provides 9 kcal/g, protein and carbohydrates provide 4 kcal/g. Adjust energy density accordingly.
Bone Content: Excessive raw meaty bones can cause constipation or dental issues. Maintain recommended 40-50% range.
Organ Meat Balance: Liver should not exceed 5% of total diet to avoid vitamin A toxicity.
Supplementation: Consider adding omega-3 fatty acids, probiotics, and digestive enzymes to optimize nutrient absorption.
Water Intake: BARF diets have high moisture content, but always ensure fresh water availability.
Adjustments for Special Conditions: Dogs with health issues (renal, hepatic, allergies) require tailored BARF formulations.
