How Much to Feed a Yorkshire 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 | 267 - 267 kcal | ~74 - 74 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 301 - 301 kcal | ~84 - 84 g |
| Active / Working Dog | 2.2× RER | 367 - 367 kcal | ~102 - 102 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 234 - 234 kcal | ~65 - 65 g |
| Weight Management / Obese Prone | 1.1× RER | 184 - 184 kcal | ~51 - 51 g |
| Growing Puppy (4+ Months) | 2× RER | 334 - 334 kcal | ~93 - 93 g |
