How Much to Feed a Biewer 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 | 174 - 294 kcal | ~48 - 82 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 196 - 331 kcal | ~54 - 92 g |
| Active / Working Dog | 2.2× RER | 240 - 405 kcal | ~67 - 113 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 153 - 258 kcal | ~43 - 72 g |
| Weight Management / Obese Prone | 1.1× RER | 120 - 202 kcal | ~33 - 56 g |
| Growing Puppy (4+ Months) | 2× RER | 218 - 368 kcal | ~61 - 102 g |
