1. What is Maintenance Energy Requirement (MER)?

The Maintenance Energy Requirement (MER) represents the daily caloric intake needed to maintain a dog's current weight, accounting for their breed's typical activity level. It's a crucial starting point for determining appropriate feeding amounts.

2. How Does the Calculator Work?

The calculator uses the MER equation:

Where:

• \( weight_{kg} \) — Dog's weight in kilograms
• \( breed\_activity\_factor \) — Multiplier based on breed's typical energy needs

Explanation: The equation accounts for the non-linear relationship between body weight and energy requirements, with adjustments for different activity levels typical of various breeds.

3. Importance of Proper Caloric Intake

Details: Accurate MER calculation helps prevent obesity (the most common nutritional disorder in dogs) while ensuring adequate energy for health and activity. About 40-60% of dogs in developed countries are overweight.

4. Using the Calculator

Tips: Weigh your dog accurately (not guessed). Select the activity factor that best matches your dog's breed characteristics and actual activity level. Adjustments may be needed for individual variations.

5. Frequently Asked Questions (FAQ)

Q1: How often should I recalculate my dog's MER?
A: Recalculate after any significant weight change (≥10%), or every 6 months as activity levels may change with age.

Q2: What if my dog is overweight?
A: For weight loss, feed 80% of MER for ideal target weight, not current weight. Consult your vet for a plan.

Q3: Are there exceptions to these calculations?
A: Yes - puppies, pregnant/lactating females, and dogs with certain medical conditions need specialized calculations.

Q4: How accurate are breed activity factors?
A: They're averages. Individual dogs may vary by ±20% based on actual activity and metabolism.

Q5: Should I feed exactly the MER amount?
A: MER is a starting point. Monitor your dog's weight and adjust as needed - every dog's metabolism differs.
