1. What is the MER Equation?

The Maintenance Energy Requirement (MER) equation estimates the daily caloric needs for dogs based on their weight and activity level. It provides a guideline for appropriate feeding amounts to maintain healthy body 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 adjustments for different activity levels.

3. Importance of MER Calculation

Details: Accurate MER estimation is crucial for maintaining optimal body condition, preventing obesity or underweight conditions, and ensuring proper nutrition.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are typical activity factors?
A: Sedentary (1.2), Normal (1.4), Active (1.6), Very Active (1.8), Athletic (2.0). Adjust based on your dog's lifestyle.

Q2: 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.

Q3: Should I use this for puppies?
A: Puppies have higher energy needs. Use specific puppy formulas or consult your vet.

Q4: What if my dog is overweight?
A: For weight loss, feed 80% of MER for current weight, then adjust to MER for target weight once achieved.

Q5: How often should I recalculate?
A: Recalculate whenever your dog's weight changes by 10% or activity level changes significantly.
