1. What is the Maintenance Energy Requirement (MER)?

The Maintenance Energy Requirement (MER) estimates the daily calorie needs for dogs to maintain their current weight. It accounts for the dog's weight and activity level to determine appropriate caloric intake.

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 different activity factors for different lifestyles.

3. Importance of MER Calculation

Details: Accurate MER estimation is crucial for maintaining healthy weight, preventing obesity, and ensuring proper nutrition for dogs of all life stages.

4. Using the Calculator

Tips: Enter dog's weight in kilograms and select appropriate activity level. All values must be valid (weight > 0).

Activity Factors:

• 1.2 - Inactive/Obese prone
• 1.4 - Neutered adult (typical pet dog)
• 1.6 - Intact adult
• 1.8 - Active working dog
• 2.0 - Highly active/Working dog
• 3.0 - Growth (puppy)

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a good estimate for most dogs, but individual needs may vary by ±20% due to metabolism, environment, and health status.

Q2: Should I feed exactly the MER amount?
A: MER is a starting point. Adjust based on your dog's body condition score and weight changes.

Q3: What if my dog is overweight?
A: For weight loss, feed 80% of MER for target weight, not current weight. Consult your vet for a weight loss plan.

Q4: How often should I recalculate MER?
A: Recalculate whenever your dog's weight changes significantly or their activity level changes.

Q5: Does this work for all dog breeds?
A: The equation works for most breeds, but giant breeds may need slightly less and toy breeds slightly more per kg.
