How Much to Feed a Cairn 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 | 424 - 448 kcal | ~118 - 124 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 477 - 504 kcal | ~133 - 140 g |
| Active / Working Dog | 2.2× RER | 583 - 616 kcal | ~162 - 171 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 371 - 392 kcal | ~103 - 109 g |
| Weight Management / Obese Prone | 1.1× RER | 292 - 308 kcal | ~81 - 86 g |
| Growing Puppy (4+ Months) | 2× RER | 530 - 560 kcal | ~147 - 156 g |
