How Much to Feed a Irish Wolfhound: 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 | 2030 - 2245 kcal | ~564 - 624 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 2284 - 2525 kcal | ~634 - 701 g |
| Active / Working Dog | 2.2× RER | 2792 - 3087 kcal | ~776 - 858 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 1777 - 1964 kcal | ~494 - 546 g |
| Weight Management / Obese Prone | 1.1× RER | 1396 - 1543 kcal | ~388 - 429 g |
| Growing Puppy (4+ Months) | 2× RER | 2538 - 2806 kcal | ~705 - 779 g |
