1. What is the MER Equation?

The MER (Maintenance Energy Requirement) equation estimates the daily caloric needs for adult dogs at maintenance energy level. It provides a baseline for determining appropriate food portions.

2. How Does the Calculator Work?

The calculator uses the MER equation:

Where:

• \( MER \) — Maintenance Energy Requirement (kcal/day)
• \( W \) — Body weight in kilograms (kg)

Explanation: The equation accounts for the non-linear relationship between body weight and metabolic rate, with smaller animals requiring more calories per unit of body weight.

3. Importance of MER Calculation

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

4. Using the Calculator

Tips: Enter the dog's weight in kilograms. The value must be valid (weight > 0). For pounds, convert to kg first (1 lb = 0.453592 kg).

5. Frequently Asked Questions (FAQ)

Q1: Is this equation suitable for all dogs?
A: This is a general guideline for healthy adult dogs. Puppies, pregnant/lactating females, working dogs, or dogs with health conditions may need adjustments.

Q2: How does activity level affect MER?
A: Active dogs may need 1.2-1.8×MER, while sedentary dogs may need 0.8×MER. Adjust based on individual needs and body condition.

Q3: What if my dog is overweight?
A: For weight loss, feed 80% of MER for ideal weight. Consult your veterinarian for a proper weight loss plan.

Q4: Are there breed-specific variations?
A: Some breeds may have slightly different metabolic rates, but this equation provides a good starting point for most breeds.

Q5: How often should I recalculate MER?
A: Recalculate whenever your dog's weight changes significantly (more than 10% of body weight).
