RER vs. MER: How Dog Calories Are Calculated
The daily calorie calculation for dogs uses two key figures:
- **RER (Resting Energy Requirement):** The calories needed for a dog to perform basic life functions (breathing, digestion) while at rest. The primary formula is based on metabolic weight (**70 x Weight_kg^0.75**).
- **MER (Maintenance Energy Requirement):** The **actual daily calorie intake** needed. This is calculated by multiplying the RER by a **Metabolic Factor** which accounts for age, activity, neuter status, and health goals (like weight loss or gain).
