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 feeding healthy adult dogs to maintain their current weight.

2. How Does the Calculator Work?

The calculator uses the MER equation:

Where:

• \( weight_{kg} \) — Dog's weight in kilograms
• \( activity\_factor \) — Multiplier based on activity level (1.2-2.0)

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

3. Importance of MER Calculation

Details: Accurate MER estimation is crucial for maintaining healthy weight, preventing obesity or malnutrition, and ensuring proper nutrition for dogs.

4. Using the Calculator

Tips: Enter dog's weight in kilograms and select appropriate activity level. All values must be valid (weight > 0).

5. Frequently Asked Questions (FAQ)

Q1: How do I convert my dog's weight from pounds to kilograms?
A: Divide pounds by 2.205 to get kilograms (e.g., 20 lbs ÷ 2.205 = 9.07 kg).

Q2: What activity factor should I choose?
A: Sedentary (1.2) for mostly indoor dogs, Normal (1.4) for typical pets, Active (1.6) for regular exercise, Very Active (1.8) for athletic dogs, Working (2.0) for service or herding dogs.

Q3: Does this apply to puppies or pregnant dogs?
A: No, growing puppies and pregnant/lactating females have different energy requirements.

Q4: 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.

Q5: Should I adjust for my dog's body condition?
A: Yes, overweight dogs may need 10-20% fewer calories, while underweight dogs may need 10-20% more.
