|---|---|---|---|
| Neutered / Spayed Adult (Maintenance) | 1.6× RER | 1498 - 1733 kcal | ~416 - 481 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 1685 - 1949 kcal | ~468 - 541 g |
| Active / Working Dog | 2.2× RER | 2059 - 2383 kcal | ~572 - 662 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 1310 - 1516 kcal | ~364 - 421 g |
| Weight Management / Obese Prone | 1.1× RER | 1030 - 1191 kcal | ~286 - 331 g |
| Growing Puppy (4+ Months) | 2× RER | 1872 - 2166 kcal | ~520 - 602 g |
