|---|---|---|---|
| Neutered / Spayed Adult (Maintenance) | 1.6× RER | 891 - 1334 kcal | ~248 - 371 g |
| Intact Adult (Moderate Activity) | 1.8× RER | 1003 - 1501 kcal | ~279 - 417 g |
| Active / Working Dog | 2.2× RER | 1225 - 1835 kcal | ~340 - 510 g |
| Senior Dog / Reduced Mobility | 1.4× RER | 780 - 1168 kcal | ~217 - 324 g |
| Weight Management / Obese Prone | 1.1× RER | 613 - 917 kcal | ~170 - 255 g |
