How Much to Feed a Soft Coated Wheaten 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 794 - 984 kcal ~221 - 273 g
Intact Adult (Moderate Activity) 1.8× RER 893 - 1107 kcal ~248 - 308 g
Active / Working Dog 2.2× RER 1091 - 1353 kcal ~303 - 376 g
Senior Dog / Reduced Mobility 1.4× RER 694 - 861 kcal ~193 - 239 g
