How Much to Feed a Boston Terrier: 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 | 398 - 693 kcal | ~111 - 193 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 448 - 779 kcal | ~124 - 216 g |
| Active / Working Dog | 2.2× RER | 548 - 953 kcal | ~152 - 265 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 349 - 606 kcal | ~97 - 168 g |
| Weight Management / Obese Prone | 1.1× RER | 274 - 476 kcal | ~76 - 132 g |
| Growing Puppy (4+ Months) | 2× RER | 498 - 866 kcal | ~138 - 241 g |
