How Much to Feed a English Cocker Spaniel: 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 | 712 - 872 kcal | ~198 - 242 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 801 - 981 kcal | ~223 - 273 g |
| Active / Working Dog | 2.2× RER | 979 - 1199 kcal | ~272 - 333 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 623 - 763 kcal | ~173 - 212 g |
| Weight Management / Obese Prone | 1.1× RER | 490 - 600 kcal | ~136 - 167 g |
| Growing Puppy (4+ Months) | 2× RER | 890 - 1090 kcal | ~247 - 303 g |
