1. What is the MER Equation?

The Maintenance Energy Requirement (MER) equation estimates the daily calorie needs for dogs based on their weight and activity level. It provides a baseline for determining appropriate food portions and nutritional requirements.

2. How Does the Calculator Work?

The calculator uses the MER equation:

Where:

• \( weight_{kg} \) — Dog's weight in kilograms
• \( factor \) — Activity level multiplier (1.0-3.0)

Explanation: The equation accounts for the non-linear relationship between body weight and metabolic rate, with different factors for different activity levels and life stages.

3. Importance of Calorie Calculation

Details: Accurate calorie estimation is crucial for maintaining optimal weight, preventing obesity or malnutrition, and supporting specific life stages or activity levels.

4. Using the Calculator

Tips: Enter the dog's weight in kilograms and select the appropriate activity factor. For puppies, use age-appropriate factors. Adjust as needed based on individual metabolism and body condition.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a good estimate but individual needs may vary by ±20% due to metabolism, environment, and health status.

Q2: What if my dog is overweight?
A: For weight loss, feed 80% of MER for ideal weight. Consult your vet for a personalized plan.

Q3: How often should I recalculate?
A: Recalculate after any significant weight change, life stage transition, or activity level change.

Q4: What about pregnant/lactating dogs?
A: These have special requirements - consult your veterinarian for appropriate nutrition.

Q5: Can I use this for cats?
A: No, cats have different metabolic calculations. Use a feline-specific calculator.
