How Much to Feed a Scottish 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 | 541 - 629 kcal | ~150 - 175 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 608 - 707 kcal | ~169 - 196 g |
| Active / Working Dog | 2.2× RER | 744 - 865 kcal | ~207 - 240 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 473 - 550 kcal | ~131 - 153 g |
| Weight Management / Obese Prone | 1.1× RER | 372 - 432 kcal | ~103 - 120 g |
| Growing Puppy (4+ Months) | 2× RER | 676 - 786 kcal | ~188 - 218 g |
