Vets start with Resting Energy Requirement (RER): RER = 70 × (body weight in kg)0.75. Then multiply by a factor for life stage and activity to get daily calories.
| Situation | Multiply RER by |
|---|---|
| Weight loss | 1.0× |
| Senior / low activity | 1.4× |
| Neutered adult | 1.6× |
| Intact / active adult | 1.8–2.0× |
| Puppy (4–12 mo) | 2.0× |
| Puppy (under 4 mo) | 3.0× |
Skip the arithmetic — our Dog Planner does it and converts to cups per day.
“2 cups a day” means nothing without the food's energy density. Divide daily calories by the kcal-per-cup on your bag.
Feel your dog's ribs — you should feel them under a thin layer, like the back of your hand. Can't feel ribs? Trim ~10%. Too visible? Add ~10%. Recheck every two weeks.
