Formula Used in This Calculator
This tool uses a standard veterinary nutrition formula known as Resting Energy Requirement (RER).
1. Resting Energy Requirement (RER)
RER=30W+70
Where:
- W = Dog weight in pounds
- RER = calories needed at rest
2. Daily Energy Requirement (DER)
DER=RER×Activity Factor
Where activity factor depends on lifestyle:
- Low activity = 1.2
- Normal activity = 1.5
- High activity = 1.8
3. Food Calculation Formula
Cups per day=Calories per cupDER
4. Weekly Food Requirement
Weekly cups=Cups per day×7
Example Calculation
Let’s understand with a real example:
- Dog Weight = 50 lbs
- Activity Level = Normal (1.5)
- Calories per cup = 400 kcal
Step 1: Calculate RER
RER = (30 × 50) + 70
RER = 1570 kcal
Step 2: Calculate DER
DER = 1570 × 1.5
DER = 2355 kcal/day
Step 3: Calculate Food Cups
Cups per day = 2355 ÷ 400
Cups per day ≈ 5.89 cups
Step 4: Weekly Food
Weekly food = 5.89 × 7
Weekly food ≈ 41.23 cups
