1. What is Maintenance Energy Requirement (MER)?

The Maintenance Energy Requirement (MER) is the number of calories a dog needs daily to maintain its current weight. It accounts for the dog's metabolic rate and activity level.

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 and life stage

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 the dog's weight in kilograms and select the appropriate activity level. For weight loss, feed 80-90% of MER; for weight gain, feed 110-120% of MER.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my dog's activity level?
A: Sedentary = mostly indoor, little exercise; Active = regular walks/play; Highly Active = daily vigorous exercise; Working = hunting, herding, or sled dogs.

Q2: Should I adjust MER for senior dogs?
A: Yes, senior dogs typically need 10-20% fewer calories than adult dogs of similar size due to decreased activity and metabolism.

Q3: What about puppies?
A: Puppies need 2-3 times MER for adults of expected mature weight. Use specific puppy formulas for accurate calculation.

Q4: How accurate is this calculation?
A: It provides a good starting point but individual needs may vary by ±20% based on metabolism, environment, and health status.

Q5: When should I recalculate MER?
A: Recalculate after significant weight change (≥10%), activity level change, or life stage transition (e.g., neutering).
