1. What is Maintenance Energy Requirement?

The Maintenance Energy Requirement (MER) is the daily caloric intake needed to maintain a dog's current weight, accounting for their activity level. It's based on the Resting Energy Requirement (RER) multiplied by an activity factor.

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 Caloric Calculation

Details: Proper caloric intake is crucial for maintaining optimal weight, preventing obesity or malnutrition, and supporting overall health and energy levels.

4. Using the Calculator

Tips: Weigh your dog accurately in kilograms. Select the activity level that best matches your dog's daily routine. For weight loss, reduce MER by 10-20%.

5. Frequently Asked Questions (FAQ)

Q1: 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.

Q2: What if my dog needs to gain or lose weight?
A: Adjust calories by 10-20% below MER for weight loss or above MER for weight gain, monitoring progress monthly.

Q3: How do I convert pounds to kilograms?
A: Divide weight in pounds by 2.205 to get kilograms (e.g., 20 lbs ÷ 2.205 = 9.07 kg).

Q4: What activity factor should I use for puppies?
A: Puppies typically need 2-3 times the MER for adults due to growth. Consult your vet for precise puppy nutrition.

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