How Much to Feed a Chesapeake Bay Retriever: 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 | 1250 - 1656 kcal | ~347 - 460 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 1406 - 1863 kcal | ~391 - 518 g |
| Active / Working Dog | 2.2× RER | 1718 - 2277 kcal | ~477 - 633 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 1093 - 1449 kcal | ~304 - 403 g |
| Weight Management / Obese Prone | 1.1× RER | 859 - 1139 kcal | ~239 - 316 g |
| Growing Puppy (4+ Months) | 2× RER | 1562 - 2070 kcal | ~434 - 575 g |
