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 guideline for proper feeding to maintain optimal body condition.

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 adjustments for different activity levels.

3. Importance of MER Calculation

Details: Accurate MER estimation is crucial for maintaining healthy weight, preventing obesity or undernutrition, and ensuring proper energy for activity levels.

4. Using the Calculator

Tips: Enter dog's weight in kilograms and select the appropriate activity level. For puppies, pregnant/lactating dogs, or dogs needing weight changes, consult a veterinarian for adjusted calculations.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a good estimate for healthy adult dogs. Individual needs may vary by ±20% based on metabolism, environment, and other factors.

Q2: What are typical activity factors?
A: Sedentary (1.2), Normal (1.4), Active (1.6), Very Active (1.8), Working/Performance (2.0).

Q3: How often should I recalculate?
A: Recalculate whenever your dog's weight changes by 10% or more, or if their activity level significantly changes.

Q4: Does this work for all dog breeds?
A: The equation works for most breeds, but giant breeds may need slightly fewer calories and some small breeds may need more per kg.

Q5: Should I feed exactly the MER amount?
A: MER is a starting point. Adjust based on your dog's body condition score and weight trends.
