1. What is MER for Dogs?

The Maintenance Energy Requirement (MER) is the daily caloric intake needed to maintain a dog's 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
• \( factor \) — Activity and life stage multiplier

Explanation: The equation accounts for the non-linear relationship between body weight and energy requirements, with different factors for different life stages and activity levels.

3. Importance of MER Calculation

Details: Accurate MER estimation is crucial for maintaining optimal weight, preventing obesity, and ensuring proper nutrition for dogs at different life stages.

4. Using the Calculator

Tips: Enter the dog's weight in kilograms and select the appropriate activity/life stage factor. Weight must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why use weight^0.75 instead of just weight?
A: Metabolic rate scales with body surface area, which is proportional to weight^0.75, not directly with weight.

Q2: What if my dog is overweight?
A: Use the weight loss factor (1.6) and calculate based on ideal weight, not current weight.

Q3: How accurate is this calculation?
A: It provides a good estimate but individual variations exist. Monitor your dog's weight and adjust as needed.

Q4: What about very active working dogs?
A: Highly active dogs may need 2-5 times the MER depending on activity level and environment.

Q5: Can I use this for puppies?
A: Yes, select the appropriate puppy factor (3.0 for 0-4 months, 2.0 for 4-12 months).
