How Much to Feed a Miniature American Shepherd: WSAVA Caloric Requirements
Energy intake calibration formulated via the WSAVA nutritional equation (Resting Energy Requirement: 70 × [weight in kg]^0.75) multiplied by physiological activity indices. Gram estimates assume standard commercial dry kibble (3,600 kcal/kg).
| Life Stage / Activity Level | MER Multiplier | Daily Energy (kcal) | Estimated Kibble (Grams/Day) |
|---|---|---|---|
| Neutered / Spayed Adult (Maintenance) | 1.6× RER | 586 - 984 kcal | ~163 - 273 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 659 - 1107 kcal | ~183 - 308 g |
| Active / Working Dog | 2.2× RER | 805 - 1353 kcal | ~224 - 376 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 512 - 861 kcal | ~142 - 239 g |
| Weight Management / Obese Prone | 1.1× RER | 403 - 677 kcal | ~112 - 188 g |
| Growing Puppy (4+ Months) | 2× RER | 732 - 1230 kcal | ~203 - 342 g |
