Calculation
RER = 70 × (30)^0.75 = 70 × 16.68 = 1,168 kcal
DER = 1,168 × 1.4 (moderate activity) × 1.0 (adult) = 1,635 kcal/day
Daily food needed: ~410g (if food has 400 kcal/100g)
Feeding Guidelines
Puppies
3-4 meals per day
High growth energy needs
Adults
2 meals per day
Maintenance nutrition
Seniors
2-3 smaller meals
Easier digestion

- •Supports immune system function
- •Promotes healthy skin and coat
- •Prevents obesity-related health issues
Formula Explanation
RER = 70 × (weight in kg)^0.75
DER = RER × Activity × Age × Special
- Activity Factor: Low: 1.2x, Moderate: 1.4x, High: 1.6-1.8x
- Age Factor: Puppy: 2.0x, Adult: 1.0x, Senior: 0.9x
- Special Conditions: Pregnancy: 1.25x, Nursing: 2.0x
