Worked Example
Complete Example Calculation
A 15 kg adult dog with moderate activity:
15 kg × 70 calories/kg × 1.3 (moderate) × 1.0 (adult) = 1,365 daily calories
Nutrient requirements:
- Protein needed: 15 kg × 2.5 g/kg = 37.5 g/day
- Fat needed: 15 kg × 1.4 g/kg = 21 g/day
- Current protein intake (250g food × 25%): 62.5 g/day → 167% of requirement
