How Much to Feed a Lhasa Apso: 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 | 398 - 541 kcal | ~111 - 150 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 448 - 608 kcal | ~124 - 169 g |
| Active / Working Dog | 2.2× RER | 548 - 744 kcal | ~152 - 207 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 349 - 473 kcal | ~97 - 131 g |
| Weight Management / Obese Prone | 1.1× RER | 274 - 372 kcal | ~76 - 103 g |
| Growing Puppy (4+ Months) | 2× RER | 498 - 676 kcal | ~138 - 188 g |
What Size Crate for a Lhasa Apso? APDT Housing Standards
Based on the APDT ergonomic standard (canine height + 2 to 4 inches, full spine length without ducking), an adult Lhasa Apso 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.
