Formula & Theory — Dog Nutrition Calculator
RER = 70 × weight_kg^0.75
factor = stage × activity × neuter × body_condition
MER = RER × factor
amount_g = MER / density_per_100g × 100
amount_cup = MER / density_per_cup| Multiplier | Typical value |
|---|---|
| Puppy small breed | 3.0 |
| Adult neutered | 1.6 |
| Senior | 1.3 |
| Working / sport | × 1.5 |
