How Much to Feed a Shetland Sheepdog: 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 | 472 - 693 kcal | ~131 - 193 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 531 - 779 kcal | ~148 - 216 g |
| Active / Working Dog | 2.2× RER | 649 - 953 kcal | ~180 - 265 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 413 - 606 kcal | ~115 - 168 g |
| Weight Management / Obese Prone | 1.1× RER | 325 - 476 kcal | ~90 - 132 g |
| Growing Puppy (4+ Months) | 2× RER | 590 - 866 kcal | ~164 - 241 g |
What Size Crate for a Shetland Sheepdog? APDT Housing Standards
Based on the APDT ergonomic standard (canine height + 2 to 4 inches, full spine length without ducking), an adult Shetland Sheepdog typically requires a 30-inch enclosure (30"L × 19"W × 21"H). For puppies, choose this adult crate size equipped with an interior divider panel to avoid housebreaking accidents.
